Beautiful piece. When I make a part and hold it up like you did it is like Christmas morning and you just opened a present. I am a small novelist and do not have a CNC mill. I have a small harbor freight mill and a Grizzly G0602 Lathe but I am going to convert booth of them to CNC. I raced Dirt cars for 33 years but now I am to old to drive so I have a custom racing shock business. When I and every one else needed a part we had to make what we needed. People like you and Fusion 360 are making our country great again. I have been teaching my grandchildren how to use Fusion 360. Take their Idea's, build it in Fusion then 3D Print and when they hold that in their little hands, I see greatness. Thank you John and Fusion 360 for making for a better future!! God Bless.

[@Abom79]

Good job John! You and I are gonna talk about the telescope Gage's when I see you in January 👍🏻

[@328DaveGTS]

he should

[@PhaseConverterampV]

You need some instruction on how to use the telescopic gauges. First , always use two hands, next , pull in and out a few times to make sure plungers are on the max diameter , then rock it while you apply screw torque to lock it. It’s very repeatable If done properly.

[@cooleffenguy]

i work at a shop that has 3 point mics and those things are amazing when it comes to measuring bores. i was never good at measuring those gauges either. nice work!

[@blakelibby2140]

Hey John, please consider doing a video just on tooling! I'm sure there are a LOT of people wanting/trying to get started with milling and have limited knowledge about the tooling involved. Thanks, and keep up the great work! Love your videos!!

[@dunichtich100]

Wenn man keine Reibahle hat ist es schwierig so präszise Löcher zu bohren^^ Respekt dafür 👍

[@nickhankins5088]

Good job! I really like showing how you walk it in.

[@chadkrause6574]

I've commented this a couple times before, but I really like the OSG Ex-Gold and SUS drills. 32IPM through aluminum and high RPMs. No birdsnesting and your haas will love it! We use it on all our parts and it doesn't disappoint!

[@occamssawzall3486]

Chad Krause I don't think the tormach could push a 1/2" SUS. The HAAS yes, the tormach? Think that's well into its stall out zone.

[@chadkrause6574]

Occams Sawzall well yea but I was talking about the Haas too. Hopefully we see more Haas videos

[@chrusb7765]

If you don't have bore mics or a dail bore gage the telescope gauges are your second best choice. By using gauge pins you are only measuring the hole at its smallest diameter and you can't check for taper. Deburring with the machine is a great idea, it reduces your variance part to part.

[@rlockwood2]

great video for explaining why bore gages exist! nice work John! :)

[@bcbloc02]

I am surprised you had that much tool deflection, but then again you are engaging the entire tool cutting edge at once. I think if you ran it as a bore op so it helixed into the hole the deflection would be a lot less.

[@barrythompson8813]

Nice job, including the packaging !

[@roylucas1027]

John, really enjoyed the video. Your presentation style reminds me a bit of Roy Underhill. A fine craftsman, with a flair for presentation. Thank you.

[@markschweter6371]

Yeah.... Chop Tree.. Split/Saw/Chisel/Turn.. Ta-Daaa.... Windsor Chair !!

[@MrGismo1435]

Awesome video. I'd love to see what the sheer hog is capable of in the new haas with the extra torque and rigidity

[@drewrogge4798]

John, Try using the "Chip breaking" drill cycle style instead of "Deep drilling" cycle style. The Chip breaking style allows for a small retract every so often plus full retracts. The small retracts have the effect of breaking the chip so you don't get the bird nests while the full retracts allow you to clear the flutes. The small retracts don't even have to include any movement in Z but just a break in the movement which will also break the chip. I wouldn't recommend a dwell with no movement in materials like stainless steel which work harder easily.

[@gwcude]

John, you are scaring me with the vise handle. You should be able to loosen the jaw carriers and slide both jaws to the center of the body if you are only going to use 2 jaws, with a small part, in your double vise. Then the handle will be engaging the hex on the screw outside the vise body again, as it should. This is how my Orange double-vise works. Wouldn't want you to goober any precision surfaces on these fine vises, while monkeying around trying to get the vise handle engaged down in that slot. Nice video as always! -- Cheers, Gary

[@dlstanf2]

Upon seeing your chips and that there's the usual "shop vac" rolling around, I thought with your new shop a central vacuum, with either a tube or floor door for sweeping chips, would make a good addition. I know, not my money, but still money well spent and you can make most of the parts required.

[@Stephen1455]

Love your dog!! Just like Diresta with Spike!!!

[@Stephen1455]

Spring cut? I'm all manual, but you inspire me in CNC!

[@nder12345]

I DO love Wednesday widget thanks for them John I look forward to some HASS action And gday from Sydney Australia

[@KenFoulks]

Why did the 2nd boring operation look so much smoother, did you increase the feed or helix angle?

[@pocketracer90]

I have a question about your tooling choice. What was your reasoning behind using the Shear Hog on an adaptive path over the Superfly while machining the whole surfaces to size?

[@MrClickbang357]

I like how you fussed over the snap gauge, the details in general! This (fussing) is not bad; it's what I call customer-less service - those details that make them repeat customers!!!

[@CatNolara]

For the part with the micing we have a saying here in Germany: "Wer misst, misst Mist" which translates roughly to "Who measures measures crap". It's all about what you are actually measuring, how you measure it and what could go wrong while doing it :) Maybe youre pressing too much on the telescope gauge while screwing so that it presses in?

[@triplem451]

Wer zweimal misst, misst Mist. ;-)

[@jasonwibbenmeyer3207]

Why didn't X and Y home after the CAM runs? Is there a way to set Fusion so that it only homes Z after a run?

[@noahmercier2111]

what are the specification or tool description for the shear hog.

[@kevingambrell]

I have to say for how interesting it is to see you make the part I cant help but think I could make the same thing in a lot less time on a turret mill. Once you factor in the time to CAD the part and so on you could have made a good part of the job. CNC to me only comes into its own when production runs are on the table. I see a lot of CNC machines being used in my game for one off jobs and I just dont see why they are not done on non CNC machines. When you machined the first bore to size it took you somthing like three passes. With the part held in a 4 jaw on a lathe it would have been done in one finishing cut after roughing. All said and done your videos are brilliant to watch, thank you.

[@princessharold]

Any chance you could do a video on material/part setup? I assume you indicate as you would on a manual machine, but I've never seen how one handles that with CNC machines. Also, it seems like you roughed a lot of material off the block you saw cut. Why didn't you saw cut the piece closer to size? Not able to hold a piece that small in the saw?

[@MinelabBob]

I do enjoy your videos. i think you should do more gun stuff though lol. i really enjoyed watching your suppressor videos and 80%'s. but i would love to see you do a baffle stack suppressor next for something like 300BLK or 9/45 cal. fill out the form 1 and lets see it come to life!!

[@tomaszstaron1408]

John could I ask 1 think? Operation starting at 7.03, is it better to lift up Z axis 10 times, or it could be faster to change in Linking staydown for "Most" and do all the almost no rectracts in Z, just go down, moving to starting point would be done in xy plane without lifting head up and down... Could you check machining time for this 2 options at this op?

[@flipdotify]

Got me thinking when mentioned the chips building up inside the vices. Is there any particular reason you don't use flood coolant over the spray system you have? I understand it wouldn't make for great videos, but on other jobs you do wouldn't flood coolant help with chip evacuation and then the chips flow off the table?

[@viperup]

John, I have a question for you. In the CAD/CAM video you mentioned using a horizontal mill strategy to clean the floor first, then using a contour operation to clean the vertical side wall. While setting that operation you have used "Radial Stock to Leave = 0.004 inches". However, when I watch this video, I can see the endmill slightly removing material from the side wall. What do you think is the reason for this ?

[@occamssawzall3486]

Alper Unal his initial adaptive roughing with the shearhog left more than .004 on the walls. Ideally he should have set his horizontal to leave the same as the adaptive left on the walls, plus an additional.005

[@jimsvideos7201]

So the holes are pretty good for size, but are they co-axial?

[@cncit]

A finish boring head is the only way to machine bores accurately and a 3 point digital bore gauge is the best way for easy accurate measuring. The mill will always machines oval holes!

[@DitzlerPhoto]

20:53 ShipStation - one of my favorite time saving devices!

[@1911zach]

John, is you control cabinet door not closed on your mill? Or is it an optical illusion?

[@robertkutz]

nice work.

[@roberttisler5027]

What kind of material are machining?

[@dougrundell947]

Why all the arcs on the first cut?

[@gusbisbal9803]

Do you have a boring head for precise holes? Do you use that on a Tormach?

[@gusbisbal9803]

You do have to walk it in as you put it but the straighness of the whole is far better. Setting it and diving down does require skill so you would be doing the same thing you did with the end mill, its just that the quality of the hole is far better due to much less tool deflection.

[@ricklynch]

Unless you have an extremely accurate CNC, with very little backlash you'd be much better off using a boring head. A bored hole is perfectly round like on a lathe. A machined hole is "step" generated. Again, backlash too. Technically the bearing will be sitting on high spots.

[@INWondeR]

Wondering what a single part like that is priced for the customer. Prototypes and one offs usually cost a bundle. Care to share?

[@adamcain4603]

Do you have a flat rate for small jobs I know are shop rate is pretty high, we randomly get people off the street and when we tell them the price there jaw drops.

[@lennysweet8336]

Hey John, Curious,.. For one piece of such a simple job, honestly how long did that actually take you from cam to cutting the stock to final finish.... I understand your filming at the same time so just estimate what that added to your total time. For me that would be a manual part 75 min. max start to finish. I run short run parts programmed conversationally at the control (Full 3 axis Proto Trak) also depending on complexity.... and use Cam for larger quantity orders if i'm running 4 vices or multiple part fixtures again complexity of part dictated my programming and set up methods, also volume will influence will influence how I fixture, and naturally charge accordingly.

[@lennysweet8336]

That's pretty good John, I estimated more like 4 hours doing it the way you did from what I saw. But I also consider the difference in someones background in how different jobs are approached and executed.... Great job with the channel I love watching and I'm extremely inspired by your progress.... Thanks for what you are doing for the community, A true inspiration!!!!

[@ello-mz6om]

Why you don't use the haas?

[@richardnix2046]

Lacking ID mics or check pins, you might turn a quick and dirty go/no go plug gauge.

[@richardnix2046]

This works well also for larger tapped or thread milled holes where expensive hard gauges aren't practical. Use your CNC lathe with a suitable insert and measure gauge with wires or thread mics if available.

[@Bartong666]

John, did you reexport the toolpath from Fusion for each adjustment or use a tool offset in the machine? Is this feature supported by Tormach?

[@Bartong666]

If you have time it might be a good Wednesday widget topic. I just started my adventure with CNC and I'm finishing building my own 5 axis machine running Mach4 and have Mach3 running on my little desktop router. As far as I know Mach supports those functions as well but I haven't used them yet myself. If you could do an introduction video to cutter compensation and maybe probing (cycles) that would be great! I think a comparison between what Tormach vs. the Hass have to offer would be interesting to see given that (as far as I know) these features are only software driven so the inferior hardware of the Tormach shouldn't cause any differences.

[@P8ntbaLLA56]

Why didn't you do OP1 during op2/3??

[@tj9382]

I hate those telescopic gauges, we now have a nice set of bore micrometers, so much better 👍 Loving the vids though dude.

[@34k5]

Interesting how the music says copyright, you. Do you have a portfolio of music you compose as well?

[@MattOGormanSmith]

On the first op, why does it lift up to do all the cutting passes front to back? I thought adaptive hogging doesn't care about climb/conventional.

[@occamssawzall3486]

MattOGormanSmith Generally it doesn't care, but the machine cares. Takes far more HP to conventional mill than to climb mill. Even with adaptive climb milling only is preferable, has to do with cutting forces, lead angles, tool geometry etc etc. a lot of math I'm not going to get into. Suffice to say climb only is optimal for most machines, unless you have a high HP high torque machine, in which case, adaptive paths for roughing are of little use since with that much HP on tap, it can take monstrous cuts in material with ease and be faster than adaptive cutting.

[@sirajshukri6520]

Why didn't you just use a boring op to finish the bearing pockets? You said it yourself boring is great for deep holes with long tools.

[@ReevansElectro]

Telescoping gauges have flat ends. You are measuring to a curved surface.

[@adamcain4603]

Instead of going back into fusion to make another pass on the hole, you could have just changed the offset for the tool dia. and rerun that tool. Just thinking out loud you probably know this already thanks for the vid.

[@sanforce]

Where can you find large chunks of aluminum like that?

[@occamssawzall3486]

sanforce metal supply yards.

[@futten3230]

why the curving tool paths? instead of going straight across?

[@CatNolara]

I think that's just how fusion 360 calculates stuff like this...

[@occamssawzall3486]

Futten Adaptive clearing path. Maintains a constant chip load including the lead ins and outs. Prevents shocking the cutter with varying chiploads

[@DogiojoeXZ]

Why not do it in two ops instead of three? You could have started with milling the step, bore, and the corner chamfer at the same time, just like you had it held in your third op, and then all you would have to do is flip it. Other than that good video!

[@chiefmachining7972]

i didn't get that either

[@CNCSKILL]

I think that such a simple milling parts could be made much more quickly if you use carbide end mills and not to the plates and instead of flattening razfrezirovki cutter boring head with the brim and not customized proofreader! To measure better ispolzovat bore gauge with a clock or a digital display!

[@Robbievigil]

Hi John!

[@jvolk0]

Hi John! First of all, great videos! Can you do one test for us. What buggs me is that "tool deflection". I don't believe that tool deflects so much, but I think that what is happening is that you have servo motor drives for your X and Y are acting different if there is some side force on endmill or not. Because servo controllers have PID, and PID is controlling motors with an difference between actual measured value and setpoint there can be bigger difference between those two values if side force on endmill is bigger. Can you do two round pockets in aluminium with same "Radial stock to leave" and then finish one with long endmill in one pass and other pocket with same endmill but short version, but use same DOC on both. Then measure both pockets. I hope you understand me because I am not very good at explaining in English :-)

[@jvolk0]

Do your cnc use stepper motors or servo motors?

[@BerndFelsche]

Enjoying all of your videos. Even the historic ones. Historically, I did some NC programming in 1981 to 1983 for a shipbuilder to pay my way through Mechanical Engineering studies at University; culminating in my final year report on the state of technology and trends in NC machines; but I've scarcely touched CNC since. Looking at a small CNC to "reboot" local manufacturing as part of a startup early next year. While it can be "cheap", off-shored CNC is also time consuming and expensive for reliable shipment; and the people doing the machining have little if any idea what the components are supposed to be doing, so they can make the wrong decisions in how they approach the machining. Prototyping with your own CNC will substantially reduce product development processes. And don't get me started on the "leakage" of IP. Couple of questions relating to this video: 1. Why did you remove "supporting" material (the step) from the workpiece before doing the heavy cutting in the hole(s)? You lost at least a third of the supporting stiffness when the vise was gripping what remained "after" the step. It's not just the tools that deflect (spring) during machining; the workpiece does so too. The rule of thumb is to try to maintain as much of the "outer" as possible while reducing the "inner". 2. Why did you reposition the piece twice when you could have done it with just once; the part-chamfer, through-hole and bearing seat; followed by the other bearing seat, remaining chamfer and then the big step? The advantage I see in the reduction is less room for error in positioning the workpiece and the chance to deeply support the workpiece during the big drilling; subject to the tool length available for the other part of the chamfer when the part is rotated for the second set of operations. This order of the operations takes into account the (probable) critical "co-axiality" of the two bearing seats. Alignment of seats would have been better with a boring bar and running the bar through the hole in the middle to reach the far seat. But if you don't have a suitable tool, you must re-position the piece.

[@BerndFelsche]

Thanks for the response. I agree that the reduction in stiffness would be very small compared to the tool flex in this case. And on third thoughts, don't forget that the workpiece may be held with the vise vertical, allowing whole-depth support very close to the where the bore is being machined. In "production", one would make a special "fixture" that restrains the workpiece on the parts of all the surfaces where the tools don't need access. With enough table space, the part being machined can be moved from one fixture to the next for a series of milling operations. The fixture for the second series of operations could e.g. incorporate an internal restraint by means of a "pin" that matches the first machined bearing seat allowing the part to be dropped accurately into a pre-defined position before being clamped. If "more than one" identical part is to be made, then "fixturing" with associated setup and tear-down times ought to be considered. Which brings me to your CNC Parts Loader on the 440: How are you going with that? I'm guessing that your spare time (ha!) is consumed with the new big mill for now. Looking forward to updates.

[@gamerpaddy]

Are people ordering such parts in larger quantities from you or is most stuff just 1..2 parts? how much do you or others charge for such a part? (roughly, this part for example) im just asking to get a rough idea whats going on in this business

[@gamerpaddy]

[@cbbowness]

Is anyone else using these orange vises in the real world? Might try and talk management into making the switch but I'm not sure how. Anyone have any good selling points?

[@alfredlyon27]

[@MolsonPeanut]

is Judd a Rhodesian?

[@Imaboss8ball]

wouldn't it be more efficient to use a band saw to cut the metal to size?

[@Imaboss8ball]

it would waste less metal. and time. especially if you cut it to a rough shape and just used the mill for what it actually needs to be used for. from what I can see you took good couple inches off in the mill. also use a band saw instead of the DeWalt. I would assume it would be faster and would waste less material. I know micro optimizations is pointless but optimization is fun to me.

[@suzukichopper]

Knowing John, if it was quicker to use the bandsaw, he would have. I know for myself and the equipment I have, doing it the way he did would have been the quickest.

[@pug2o5]

David Serrano those TCT saws can cut material very quick, and still leave a reasonable end finish. super fast when cutting tube or box section. way faster than a bandsaw for that

[@Sketch1994]

Band saws are slower, tend to cut at an angle and require replacing more often! The disc is a lot faster as it can have much bigger teeth and is more rigid...Also with a band saw you can't cut something at angle cause the band might snap and when it snaps it's nasty!

[@ABitOfTheUniverse]

[@Stephen1455]

[@craigs5212]

You are interpolating the hole, the tolerances of both axis and the backlash numbers all add up against you making a hole that is not as round as it could be. For an accurate hole consider a boring operation. Craig

[@occamssawzall3486]

Craig S Theoretically backlash stack in the screws is a thing, but it's only a few tenths at best. 8 tenths max on a machine like the tormach, closer to 4 tenths on the HAAS, which does have backlash compensation. Circular interpolation on higher end machines, DMG Mori, Makino, Mazak, you can interpolate down to 2 tenths or better. The DMU I run will hold +\- one tenth OD and ID 2 inches deep, cylindricity within 3 tenths. I haven't used a boring head in 2 years.

[@tsw199756]

Occams Sawzall Yeah but if you don't have a solid foundation, backlash comp, ball screw mapping AND have it shot with a laser at least once a year. Then you better bore the hole. Even if you do have all those previously mentioned things in place and some stumblebum crashes the machine then you are still screwed by interpolating.

[@occamssawzall3486]

Cad-Cam_Man The DMU I run is 12 years old on wooden floor 4 stories up in a mill building built in 1874. Been crashed more than once (not by me) and hasn't been lasered in 5 years. Still holds a tenth all day everyday. Just did 25 delrin parts that needed a 3mm bore and slot an inch deep +\- .005mm. Did it with a 1/16" endmill. CMM showed less than a 2 micron deviation between all 25 parts. Machine build quality, thermal comps, glass scales and full axis and casting chilling helps a ton ;) Boring heads are too time consuming for me and a waste of a perfectly good tool pocket

[@tsw199756]

Occams Sawzall I'm skeptical that the plastic you are machining would hold 2 microns from one day to the next. Any Delran, Acetal, nylon etc. I've ever machined measured one size today and another tomorrow. Machine 4 stories up on a crooked floor, crashed by stumblebums. Things don't add up in my mind.

[@occamssawzall3486]

Cad-Cam_Man I got the CMM print outs to prove it DMU 50 Evo, full precision package on it with the 50HP spindle. Full glass scale feedbacks, chilled everything including rotaries and casting. I'd like to take some of the credit though 😁

[@gusbisbal9803]

If you insert a spindle reversal command at the top of the peck drilling operation you will get rid of the birds nest. There is a Haas Tip of day video on it. kzbin.info/www/bejne/mmKkhaGqfcqgfs0

[@beliasphyre3497]

You get paid by the hour, don't you. Why else would you waste you're time like that? #0. Check with the client on that notched out corner, if you could get away with a fillet, and how large of a fillet. This may save time later. A good designer in CAD could have caught this. #1. Don't waste you're time making a pretty metal block to start with! You said 3 ops. You just did 6, and you haven't even started. Clamp it in the vice flat, sawn sides out, propped up on parallels so you can profile the part. Face it, profile it. This is where that fillet comes in handy if you have a tool small enough to get in there. Use a chamfer tool to cut that chamfer. #2. Face off the other side. #3. Hole on the notched side. Drill it, counter bore it. If your looking for tight tolerance, leave 5-10 thou. for a finish pass. Any less, and you piddle around like you did, trying to get the machine to bite into too little of material. If you can't get away with the fillet, remove it now. #4. Counter bore the other side.

[@occamssawzall3486]

Belias Phyre A design change request and still takes you 4 ops? I can do it in 2, no design change and yes on a 3 axis. 5 axis I would do it in one op 😉

[@GregBurgess360]

I agree, no stress concentrations too.

[@beliasphyre3497]

[@feltonissimo]

You need to buy yourself some bore micrometers.

[@Cinnabuns2009]

Endmill length is logarithmic as to the deflection so 6mm longer is going to deflect a bit. 12mm longer is going to deflect more than twice as much, 24mm longer is going to deflect more than 4x more. Also, IMO, with the length of that mill, you're turning it WAY way way too fast. Its not chattering and you're in aluminum but still. I turn 32mm length (1 1/4") endmills at 2500- >12000 where as a 2" endmill I'll turn at typically 800-1300 rpm otherwise you can see tiny chatter in the finish even though you can't hear it in aluminum. You also get a more accurate hole with less deflection and much nicer finish interpolating your bore at slower feed/speed. I guess I could just say, "Nice Job!" and move on or not post at all. Maybe the later is the best option since you never reply to anything I ever post. Lesson learned.

[@cncit]

[@lukaskuhl902]

[@n8bot]

Hi, I love your videos, but can you please work on the audio a bit? Lower the sound of the machines so that it's not deafening compared to the sound of your voice -- ie way quieter than the sound of your voice. Please! It's jarring to be watching a video in the background, and then to suddenly feel as if I'm in a CNC shop. It's fine if there is some machining sound, but lower the loudness of it please!

[@n8bot]

Thank you so much!

[@foxyrollouts]

I wonder if he knows what hearing protection is?

[@aj7utu]

Entire bore should have been BORED in a single operation. Always as a practice. Do not trust concentricity of interpolation, especially on an $8412 machine. Do you want to fight with a naive customer who doesn't have circularity and concentricity spec on that feature, and can't press his bearing in despite it being "in tolerance?" I wouldn't trust this on a new VM3. Axis reversal errors kill concentricity and circularity.

[@Stephen1455]

Bird's nest! Just kidding!

[@ErwinEnterprises]

That was dumb. Just use a drill for fast material removal, then bore to size.

[@alphgeek]

Normal twist drills aren't accurate enough for bearing seats. An H7h6 fit at that diameter has a maximum clearance of 0.041 mm or about 1.6 thou. I wouldn't even trust a reamer for that accuracy, even if I had one in the exact size needed. Not to mention that drills aren't usually flat on the bottom.

[@philbx1]

Exciting boring John!

[@robertgraham1049]

this is what boring heads are for

[@JonesAndGriesmann]

please learn how to use a real micrometer, I know that one is quick to read but the accuracy doesn't compare to a vernier micrometer.

[@sirajshukri6520]

RtSROFLhacks digital or vernier makes little difference for accuracy. It's the quality of the mic that matters. I can't speak for tormachs micrometers but the all the mitutoyo mics (digital or analogue) I have used have always agreed with whatever gauge block I check them with.

[@JonesAndGriesmann]

Siraj Shukri tell that to my boss and you would lose your job on the spot.

[@sirajshukri6520]

Good thing I don't work for your boss then. Honestly though what's so magical about a vernier mic?

[@thunderthormx]

+RtSROFLhacks sounds like a shitty boss

[@JonesAndGriesmann]

Thor Njalsson digital micrometers are accurate to .001, but I work with a .0002 tolerance I would love to see you try to use one of those to hold a .0002 tolerance.
