this should be a series

[@larsolav2009]

Looks like a lathe part to me. Bar-feeder and bar stock and this could be a lights out high-volume part.

[@grafixbyjorj]

Yeah, if you have the lathe for it (dual-spindle, live tools etc.), it's a no-brainer. I'd even use tube stock if you can find the right size, as I do on my ring-shaped parts. Less waste, less machining time, cheaper stock in my experience.

[@billweber1340]

Usually you drill deeper than necessary when tapping a hole so you can tap to full depth. If you run this program, it will crash when the tap bottoms out because he didn't drill deep enough

[@andrejsgelins9296]

Moving tapping to setup 2?

[@gredangeo]

@@andrejsgelins9296 Why would you want to tap a hole not in the same setup as the drilling? You're just asking for problems, when the alignment isn't perfect.

[@SpencerWebb]

Brilliant video!! Thank you for the excellent teaching. 👍👍

[@chrisj4570g]

Im a *balanced* enough individual that I recognized that part even before I saw the logo. 😉 I’d like to see them made in a strip. I can convince the customer if need be. 😬

[@SpencerWebb]

Chris: 🤣

[@scottwatrous]

Awesome video. A lot of good insights in here. One note about the Cogsdill I found out recently doing some repair work. If your holes aren't very round and your material is hard at all (in my case basically a keyhole shape) you will absolutely, immediately, destroy the cogsdill tool. The obround area will cause the spring-loaded blade to extend out into the void, and then hit the side wall, which at least in steel shears the blade and grenades the shank inside your part. That said, I absolutely love the cogsdill tools and when you are dealing with normal holes they work scary good.

[@blakecrawford5101]

Man was this instructive and interesting! Def should be a series.

[@BlackSmokeDMax]

This was fantastic! More like it, please!

[@piccilos]

love this style of video. And getting to watch a part go from one off to production programming would be wonderful.

[@CNCMachinistEducationNetwork]

very nice I had to visit that engrave drag tool- we used to use a compression engraver for anodized parts that varied in height. Then we started using the Haas probe to reset Z value for a ER16 collet held engraver. Either ball mill or engrave at 10K RPM. Was seriously looking at AirTurbine to go 40K for engrave but I may look at the drag tool. I like 90 deg Mill/Drill to spot/chamfer and also contour chamfer and normal jobber drills unless $ warrants it

[@dav1dh0ff]

I'd love to see more like this.

[@multiHappyHacker]

that is like a perfect part for my live tool lathe, lots of chamfer cutters because of the chamfers though. done in one setup.

[@macmaniacal]

love this. Very practical

[@prodesign8189]

Thanks John. It's always good to brush up on some things by seeing how you do them. I always find something I didn't do before and I went into this video feeling like I might not pick up new ways to skin a cat. But not so! Merry Christmas to you and yours!

[@hyperformancellc]

you can right click the entire operation folder (set up) and get a total run time on all operation in that set up.

[@RambozoClown]

Something seems wrong with the chamfer change from a contour to a plunge. I would expect a lot more time savings. Also since the endmill is so close to the pre drill diameter, I bet you could just plunge that and not do the helical ramp and shave off even more time. If you slightly offset the plunge point, from the drill point the chips will break and not make long strings that wrap around the endmill. Then for that last little bit in a high volume production program, I always go in and tweak the g code by hand to optimize rapid and linking moves, especially when two operations use the same tool. Most CAM software treats each op as it's own self contained thing and not part of a whole program. For example doing a retract and rapid back to the center of a pocket then going back to the same place to start a finish contour. Just leave the tool down and feed or rapid into position. That and doing XYZ moves instead of XY then Z. It all adds up and I have been shocked at how much time can be shaved off a program with no loss of quality in the part.

[@queuing89]

That video was GRRRREATTTTT, a quick run through of a lot of features without dwelling on the same thing for too long MERRY CHRISTMAS NYC CNC

[@gaminggami4138]

Great video!

[@SaltCreek83]

You’d save time to make the feed plane of the chamfer tool to below the part face by enough to just clear the corner of the hole, then the tool only feeds down maybe .030” or so instead of feeding all the way from .050 above the part.

Another way to save time is to disable the feedplane. There's often no need to have the tool plunging with feed-rate (or worse plunge-speed wich default value is ridiculus low) dosn to the lead-in move Just rapid down to the horisontal lead-in (and get rid of the vertical ones that are stupid when the tool is still in the air)

[@LumaLabs]

If you're going to adaptive off the back side, shift the part so that Op1 only has 0.010" or so of raw material, and ditch that initial facing operation.

[@jasonshane4606]

Thank you.. it was very informative...

[@cavemansmancave9025]

Merry Christmas, John. Thanks, John

[@ScottMoyse]

In case it helps someone... I wrote this blog post a while back which includes a template for backside chamfering... the expressions would need a little tweaking to get it to work with Trace, but the framework of the expression is there. blog.cadpro.co.nz/manufacturing/undercutting-backside-chamfers-in-fusion-360/

[@3073Sean]

John, awesome vid. Please do one on cutter comp and the two other settings and how they relate to HAAS control in offsets

[@shanerdx9929]

Question.. I may have missed it but on the second op you are chamferring all the drill holes that were made on OP1. How are you lining it up so that the part is in the correct location? Would be keen to know. Same for OP 3.

[@TETabor]

John, I would be interested in seeing this as you mentioned, machining in a fixture using square stock VS the round stock

[@dd8pz]

It's possible to make this part efficient on a cnc-lathe?

[@paddyflake]

It ought to be a mill turn center at least, but I think that would be the more efficient way too 👍🏻 However: you got to do with what ya got 🤷‍♂️

[@dd8pz]

@@paddyflake The lathe meet live-tools and a y-axes. Many modern CNC-Lathe are equipped with this options. Especially because John has a lathe model ST20Y from Haas in his shop that can do that.

[@Sicktrickintuner]

Looks like a hydraulic gland end. Looks like a perfect lathe part with live tools

[@shnap4oo]

I'd like to see more review of other ppls parts. gave a lot of insides. The drill/tap part was just mistake from hurrying. I wanna see Mr. Rob Lockwood do one of yours too :D

[@hansdietrich83]

interesting question/challenge: could you chamfer the sidehole using a lolipop cutter in the Coordinate System from Setup 1? that would be a pretty complex toolpath and I would like to know if it's possible in F360

[@seansmith4886]

Yes you can use the flow tool path, very easy to program

[@jamescarter9147]

Yes but the hole would not be there to chamfer at that time.

[@hansdietrich83]

@@jamescarter9147 obviously, but that's not the question...

[@MUDMAD83]

Any chance you could check one of my fusion files if it can be done

[@ezmac8185]

Kings throne game looks good.

[@mitsmillman1652]

The solution is always buying more carbide

[@dickp812]

Makes me cringe , telling people they don't need a center or spot on a Jobber length drill, We run 135 deg. split point drills all the time, the split makes the drill cut free 'r doesn't replace a spot. And please I have great respect.. I guess I just would argue that one..

[@MrNerfornothing]

Also spot drilling is good for chamfers

[@Verifraudreports]

Ohh god.. i had to do this at the last contract i had... 4 different cam programs.. and i had to got through 800 garbage parts to fix all the runtime flaws.... 7th circle of Hell

[@TommiHonkonen]

quote me 100 000 of these on a two turret 2 spindle lathe and ill blow our mind

[@MIGuy]

never ask a barber if you need a hair cut.

[@kanoa9321]

Saved 1:41 in CAM, but in real life you broke a tap and ended up with holes that aren’t threaded thru. . . .FAIL

[@aarongillis7404]

No one cares

[@ericbeckers2673]

Programming?

[@palmerinsull2455]

Programming by hand used to be the standard/only way to create tool paths so I think that’s why it’s referred to that way. Many NC machines have the ability to write (program) lines during operation, although in using a hobbiest desktop machine I dont have too much experience with it.
