Abom79 Parking Attachment! Part 1 Widget96

[@Abom79]

Awesome John! This project on your end is much like how I have been building the other components. Your showing different ops on your mill, different cutters, and trying to push it. Very cool to see that. I like building those projects the way I do because I shows many different ways to do things in the machine shop. Now on to part 2!! 👍👍

[@toast47624]

I have just brought my first CNC mill. I have little idea what I'm doing. Sadly it stopped working soon after I got it. So I find myself in the deep end. Installing new drivers and breakout boards and a new spindle motor. Had it not been for the likes of you I may not have had the confidence to have ago at it. I have battled and fought for every square inch so far. But I see the positive side to this. I now understand and know every component and no matter what goes wrong in the future I can easily fix it.

[@Dudleymiddleton]

It's so satisfying and therapeutic to watch a machine like this producing such consistent chips, almost resembling aluminium chips? That tool must be perfectly sharpened and it doesn't seem to want to get blunt at all! - but it is quite a bit harder than the 1018 mild low carbon steel though which must be like cutting through cheese! Great video! :)

[@JPGuay]

Quite magical. Outstanding demonstration of your art John. Thanks for sharing !

[@isabellaman2545]

Impressive finish ramping with the ball end mill. Wow

[@chrisyboy666]

Regarding the blue hose when hitting feed override.Every machine I've worked on that you rigid Tap wether it's G code or Macro or canned cycle or subroutine.You cant override or change the feed when in cycle tapping.It physically won't allow surely you can go into the Plc and close a gate and lock the feed to safeguard against this.

[@Joesmith-pl4qb]

Awesome! Your commentary is great! Having operated only hobby manual machines, I find this absolutely fascinating! It will be great to know where it was made when we see it later on Adam's K and T Mill.

[@KenToonz]

John, this was an awesome two part series! And, thank you so much for pointing out the No Engagement Feedrate! Once you gave it a name I knew it had to be somewhere and sure enough it's on the last tab rather than the Feeds and Speeds tab. No wonder I never saw it!

[@w056007568]

Quite fascinating to watch bearing in mind it is all derived from and controlled by electronics - I'm amazed!!

[@MacKenzieOfSweden]

Thanks for putting up the metric feeds and speeds.

[@jessefoulk]

The quality in the video recording is stupendous.

[@bcbloc02]

I noticed the chatter seemed to only show up climb milling in the x-I wonder if your moveable vise jaw has some side to side slop?

[@Yeetus-Veritas]

Amazing how much the mentality of material removal changes in a year. Roughing geometries only to clear them away, drilling ops, chamfering, etc. It would be awesome if you, as a primarily self taught machinist did a mass revisiting after "X" years to talk about the rights and wrongs of your own processes. To hear the latent advice you would have liked to have given yourself. But maybe that would also reopen the door for trolls, negative-nancy's, and the "my way is the only right way" comments.

[@ronfish8375]

awesome video. Just a little constructive criticism, there's a substantial audio / video offset towards the end of the video.

[@Mo-ih4gr]

I don't understand why the cnc milled the top part as part of the parking part. why not just roughly mill all of the metal off that u need to and then start shaping it in detail

[@TheSageDad]

Had same question...

[@feltonissimo]

I agree. It's a very inefficient toolpath. But interesting nonetheless.

[@firefighter494]

I've never messed with cnc only mill and lathe but thought the same thing

[@adamcain4603]

Most of the carbide end mills I have used were always ran dry, I am not sure what company they were from. But we were also machining hardened D2 too steel. Have you ever used a carbide end mill that are specified to use no coolant?

[@burkemoras]

On a manual mill, you can't trust the moveable jaw to be exactly the same as the solid jaw. Sometimes, you can move the cutter over the moveable jaw and still bump into the back jaw.

[@daveticehurst4191]

What was the purpose in doing all that fancy rotary milling at the start on the right hand end, only later to machine it all away before making the stairs cut ? Would it have not been simpler and quicker, just to have milled it away as a relief, then rotary mill the shape later ?. I know nothing about working cnc, only conventional milling methods.

[@nf794]

Cad cam often are model aware and concentrated on tool life and constant Engagement of the cutter. Smart Toolpaths automatically not so much.

[@wtopace]

Great video! You might want to check your gibs. I had chatter when transitioning between x and y due to a loose y-axis gib. Afterward adjusting it properly - completely silent when machining circular bosses and pockets, previously I would receive chatter similar to yours during axis transitions. Keep up the great work!

[@jmvar]

Hi, thanks for all of the videos. They are super helpful for those of us trying to learn. Did you run this job with the spindle belt in the upper or lower position? Do you change the position of the belt, and if so, can you explain the thought process behind belt position on the PC1100?

[@dinxsy8069]

Awesome product, on to part Two!

[@brandonl.5998]

What was the motivation behind using the 1/2" drill to pilot for the 11/16" drill? Just curious, I was always taught to use a drill fairly close to the size of the chisel edge of the drill bit. Also, in my experience if I go too large it ends up breaking the corners off. I've been looking forward to the Abom Part for a while, love the long machining videos. Just another thing, the sound the CNC makes at 10:04, I'm not sure why but I think it's great. Perhaps not for the machine no, but it gives me the impression that the machine is really taking a grandiose cut and handling it well. Just another another thing, ran my first personally designed, and programmed part on a HAAS TM-1 this Tuesday, it was an upper desk leg for a desk that I have designed for my senior Precision Machining class project. I'll find a way to post pictures once it is finished if you're interested! :D

[@specforged5651]

So what is the blue hose all about? Sorry, just starting to watch your videos and loving them so I will be rolling through them one after another from now on. Thanks!

[@occamssawzall3486]

Why beat up in he finisher on the second toolpath? Isn't that what the rougher is for? Beat up the rougher with material hogging. Save the finisher for finishing to size.

[@dougankrum3328]

I'm thinking of buying a medium size 'home shop' bandsaw soon....about 8X10 or so and preferably a swivel-frame saw...How do you like that Ellis..? Do you use a tool checking set-up to measure tools and then enter offsets in the CNC ? How about that Tormach....I like the small 'home-size' unit...cost?? I Found your site in relation to the excellent ABOM79...!

[@dougankrum3328]

NYC CNC Thanks for the reply...My last job we used a lot of Ellis bandsaw blades on vertical bandsaws...3/8" X .025...M-42 teeth welded on....cut 1-1/2 to 2" stacks of Galvanized steel sheet...HVAC ductwork...

[@Malorie001]

Just curious here. Why the climb cutting during your roughing operation?

[@silveradoman298]

Great packaging for shipping John!

[@GeofDumas]

I love the little "damnit! Forgot to ____" notes haha. Also, impressive performance from the tormach. I've been a bit down on them lately but that's a nice big pile of steel it moved!

[@GeofDumas]

Nah thanks though. I just found out a bunch of parts that I'd made a thousand times over before arent to spec. Seems something went wrong after about 150 parts into a 600 part batch :/

[@johnnywayne7654]

Speaking of your no engagement feed rate, I notice that your trochoidal milling does the same when it loops back. Is that a setting in your CAM? I've used it a few times, normally with a higher hp machine and a huge MRR, but even on this machine, I'd figure it would code with the different feed rates. Just wondering.

[@johnnywayne7654]

Also, most machines don't recognize over rides when tapping, is that different on the Tormach? Keep on keeping it real bro, awesome vids!

[@trued2010]

It seems to me like your Y axis on that machine moves a little more than it should. It just makes a little more noise to me when moving the part towards the back of the mill. I'm not a machinist so i don't know if that's common, or not an issue.

[@AmateurRedneckWorkshop]

I bet even a super machinist could not turn out that part faster than the Tormach. Keep on keeping on.

[@konobikundude]

I wonder if there's some software around that you can use to create tests against your CAM to ensure that they match your best practices. Run a test script before transferring and it'll remind you if you've forgotten something.

[@konobikundude]

There's lots of simulators for gcode available, so that's not tricky at all. I would have thought it would be trickier to recognize the actions as things to register against. Do you know if fusion can generate annotated gcode describing the steps being taken?

[@garyschmidt4213]

on programs with tapping operations I always tend to put a M00 after the operation before tapping so I can change them all back to 100℅

[@InspireCNC]

what is that edge finder gauge called? i need one of those.

[@WolfgangEgger]

+NYC CNC: just curious: Are you recycling all the chips that are flying arround?

[@Lolatronn]

May i ask whats the blue hose supposed to do?

[@SwissplWatches]

This is just beautiful.

[@benstrock]

Just curious why you machined the part in a climb cutting motion. Does cutting with CNC not matter when deciding on cutting directions?

[@StepSherpa]

to my knowledge climbing is What you want to do, especially on stainless

[@benstrock]

Interesting, I could see maybe doing a climb cut on a finishing pass, but on a rough? Well it seems to work.

[@mlnunnari]

have you looked at using Udrills instead of HSS Twist Drills at all?

[@r3vo830]

Don't think he can utilise those drills on the tormach. They really need to be pushed. Though, it might be worth a try.

[@mlnunnari]

+NYC CNC they are a carbide insert drill. Great at large holemaking operations. Most tooling companies have them Personally I prefer Seco ones but companies like Sandvik, Iscar, Mitsubishi, Walter etc etc all work just as well

[@r3vo830]

www.sandvik.coromant.com/en-gb/products/coromant_u?Country=aw

[@chrisyboy666]

You would only use a U/drill insert drill/ cam drill in a high volume production environment when you had many repeat holes and you were chasing cycle times you need through spindle coolant for the drill to work also his spindle does not have drive dogs so he won't have the torque on the machine he has to optimise a U/drill

[@mlnunnari]

+Carlos that's not correct. I use udrills every day for a jobbing shop. I don't have through coolant and I hold them in an er32 spring collet mostly.

[@FesixGermany]

I love closeup footage of cnc operations.

[@tobyw9573]

All those resonant frequencies going off when milling and drilling... Like a multiple tuning fork!

[@themaconeau]

Smokin! >.< Is that normal operation or lack of lubrication?

[@RobertKohut]

Great video!! Coming here from Adam's channel.

[@stahlinstudios2067]

Awesome series man! That is a hell of a part for a tormach.. Do you find that your MQL cooling system helps with steel parts? When I cut steel with carbide I tend to run straight air, but for me it is air or flood. What advantages do you find when running MQL on big steel parts like this?

[@dorsetengineering]

One thing I am curious about, the tool path for the cleanup of the stepped slope (using the ball end mill), the rapid that brings the tool back to the bottom of the slope for the next cut, why is there so much movement away from the part? Surely cycle times could be increased by just lifting off the part by .1mm and running back 'down the slope'? Obviously this is a function of the cam engine in 360, but is there an option to improve the efficiency of these areas of the tool path? Along the same lines, with the peck drill cycles, why lift the drill all the way out of the part? If I were drilling that on the Bridgeport I'd just lift off the feed handle for a second to break the spiral and get back on the feed. Hugh, manual guy, no cam experience yet :)

[@DavidVanstone]

Generally you would get the whole program done and working safely, and then tighten everything up once happy with feed, speeds, and clearances. Once offs generally aren't worried about in tightening things up.

[@TylerBrigham]

wait... tormach machines take feedrate overrides during tapping operations?!?! thats nuts. ive never seen a machine that applies any overrides in a tapping op, both mill and lathe lock it out to prevent dumb stuff from happening. pretty much writing off tormach based on that alone

[@kopsik111]

Increase your RPM...half inch endmill on your tormach should be maximum rpm. If you increase your RPM you can increase feed rate and use smaller WOC due to the lack of rigidity.

[@mattcurry29]

Lol John, I do the same damn thing in MasterCam but i'll stop and repost to get that backfeed rate up. Do you feel that this is about the max for a TorMach?

[@adamonline45]

Ahhh, I just realized what that haimer does after seeing it in your videos a few times... Now I feel... Burdened by the old fashioned things I use... :D

[@dougrundell947]

Why are you climbing around that block?

[@robertstorms6203]

Because that's how he wants to do it.

[@futten3230]

whats with the blue hose?

[@bigwigvideos]

Why do you hit the part with a hammer after it's already tightened down?

[@EcProjects]

looking good!

[@c5back9]

What is a parking attachment?

[@brianheagren3578]

Just what I wanted to know..I googled it,and now I know..It looks just like the thing that is being made there..If you have to park your car,in a small space,you can smash your way in,with one of these..Illegal in most states.

[@StevenRosburg]

Awesome, I love watching the magic happen!

[@JustinAlexanderBell]

How flat is the surface after using that flycutter?

[@HarilIshai]

The drill birds nests: Is it possible to just lift the drill a little bit frequently to break the chip without coming all the way out. It wouldn't be much slower as you'd not be moving far, but it'd surely make the long strings of flailing metal go away

[@Apex59]

Is it just me or is the audio out of sync with the picture on this video? I've noticed this a lot on NYC CNC videos since about the time John moved to the new shop, but haven't seen anyone else comment about it. It seems to be worse on longer videos.

[@DSCKy]

I was hearing drilling noises when the drill was out of the hole. Tried to stop/start to re-sync (which sometimes works), it didn't.

[@63256325N]

Cool vid. Thanks. How long did it take you to program that into the machine?

[@63256325N]

Thanks...

[@adavid7901]

You need to use chip thinning to increase feed and increase the rpm to around s4250 for more sfm.

[@braddles345]

Was it just me, or was the audio a bit out of sync? Not really important, just noticed. Great video! Always love seeing what a ball can do to a profile! Learning on the old CNC machines at University, having a lot of fun, but have yet to do anything too complex. Although, gotta really know your code for those old beasts as they don't always like the directly generated code. Still a ton of fun! Great video, watching No. 2 next! Brad

[@pedrogramos]

what is the reamer for ?

[@samboles8796]

Pretty cool dude

[@deej19142]

Machining art...Awesome.

[@Der_Drache]

try for the first Lakeshore mill 8000rpm, 0.14 mm per thoot and 0.8 mm stepover. should sound better.

[@jackielegs]

I've been watching Abomb's series. Its awesome to see you guys team up. I was just wondering why you used a such a long drill instead of something more rigid. Looked like you had more than enough clearance. You may have mentioned and i missed it. Good job all around though.

[@MrDaniell1234]

you need a bigger VMC but you are pushing the machine

[@MrDaniell1234]

what is not on the list

[@peterplatt72]

what's the point of the blue house? I'm kinda new to all of this so please excuse me lol

[@lincolnmetal1]

a lot of the roughing could have been done with an inserted mill and plunge milling...much faster, and way easier on the tools. From the sounds coming from that machine it would probably be easier on it too...

[@lincolnmetal1]

thats surprising that you havent had much luck. By inserted i was thinking a 5/8" or 3/4" 3 insert mill. you could go it with a bull nose endmill too.

[@overkillaudioinc]

Abom watcher here, checking it out!

[@robertkutz]

very cool .

[@jcottingim]

love your vids.. Hate the sound sync problems.

[@TheMetalButcher]

Probably should have just jumped straight to the 11/16 drill. No need for the 1/2".

[@TheMetalButcher]

Carbide? I've got loads of HSS drills of every size, they just add up over the years. They always seem to be dull though. :P I throw the dull ones in a bin and go a sharpening spree for a while. You probably already know this, but it's bad on the flutes to drill a small amount, especially by hand with an uchecked feedrate. If you are going to drill a pilot hole, try to find one just about the same size or a hair smaller than the web. That way it keeps itself centered better. If that is not practical for some reason, the rule I use is to always have the pilot drill be 1/2 the size or smaller than the main drill.

[@stuarthardy4626]

John great video Seem like the adaptive is being a bit aggressive on the corners But what in the blue blazers is the advert in the middle not impressed with that at all but I assume it's not you I do hope it's not Stuart

[@davidfe47]

Great first part. Just finished watching it. 39" LCD TV makes it almost like being there. Final reaming was hypnotic. Almost as good as some of the shaper motions. Question - would another full simulation have caught the Boozo [Ox Tool Moniker] oversight of updating the Fusion 360? Suggestion - use a laser pointer to feature some things as you does these wonderful longer and more complex projects. John - thanks for all of this.

[@conrayjones9290]

I wish I could buy a Tormach in my country.

The thumbnail is so misleading in the thumbnail the part looks tiny

[@MF175mp]

19mm is about 0.7480, not 0.7505

[@kmcwhq]

Reamer.....19MM = .7480 not .7505

The devil is in the details. I was just about to make the same comment.

[@kristoferjonsson3362]
