CNC Machined Pinions Modified & Improved Workholding Fixture 

I love how you show how you're learning and even the errors that come up. Knowing that you won't send a part to customer because it doesn't have a perfect finish tells alot. I know the feeling, I'm a perfectionist as well.

My favourite part of the week is Saturday nights with Adam Booth, keep these awesome videos coming!

What I find amusing is that this part was clearly designed in metric dimensions but it got changed to inches for manufacturing. That’s the best way to run into tolerance problems when you need a precision fit.

It's cool to see how a really experienced manual machinist learns CNC machining. Hands on the controls, watching every movement of the machine, and diligently controlling the rapids to prevent crashes.

First Thing.. Make a Mark on the Collets to indicate where the slot is.. that will save you a lot of fiddling..especially when you're working for a customer.. he pays you to produce, not to Fiddle

I appreciate the cnc learning videos.

As you get comfortable with the CAD/CAM software, and start to gain confidence in what's going on, you really begin to grasp how much power and flexibility is at your command. Of course, you also get cocky and break some tools, but that's part of it, lol. When you settle in and gain a working command of the stuff you do a lot, it's like you found a Turbo button for your work. The software is so huge and comprehensive, it takes years to really master the real breadth of it, but that's fine. You almost always use a few main components, and those become second nature, and you get fast and efficient with them. Manual work will always be a go-to for a real old-school tradesman, and you'll always know when to just chuck it in a lathe and start indicating, to save time and effort. For production work, especially though, gaining the skill in CAD/CAM will pay off bigtime.

These CNC videos are great. Nice and slow, explaining so much. I feel like I am learning a lot. Thanks

Love seeing your confidence grow over the months! Go go go 💪🏻

It will become second nature to you. Patience. Nice job.

G'day Adam. The CNC worked out really well. Slowly your getting there & living the experience. Keep them coming. Thanks

Thanks for the video! Helpful hint: Make a mark on the face of your collet that aligns with your keyway for quick alignment with your setscrew. Same technique works for many other types of situations where you have a blind feature you need to align.

More fun stuff from Adam, congratulations! What I like best is how you are able to carry so much of your manual machining experience and skill into this new world of CNC. I know that this a recurring theme for me, but I agree with Bert Blankenstein that you could improve your workflow and the quality of the resulting product with some judicious use of the Renishaw Probe. Set the depth stop approximately, then crank it down tight. You already made a gauge piece of the diameter of the stock and the proper length of the finished part. Create an operation 0.5A (or rename the ops 1 and 2). This new op will use the probe as a tool to find the z coordinate of the end of the gauge piece, then use that to reset the z coordinate zero point to be the other end (where the stop is). You would use operation 0.5A every time you set up a run or had to readjust the depth stop. Also produce a modified step 0.5A and call it 0.5B. Here you want one (rough) end of the stock to be at the (adjusted) z=0 and the other end to project far enough beyond the finished length to be able to face both ends. So, if the rough length is not big enough to produce a good part, have step 0.5B declare an error and stop. Otherwise, the rough length tells step 1 where the facing tool will make first contact. Sorry about the funny names for steps. I don't know what naming rules your software has. So, for the time that it takes to write two very simple operations you can cut down on setup time, gain greater accuracy, and warn the operator of an out-of-spec blank. I think that the Renishaw probes are all accurate to better than half a thou.

It works well,Adam.Thank you.

Thanks for sharing. Had to rewatch this episode, I had the flu when this one dropped and I was totally useless for a few. It great to see that you are thriving in your hopes and dreams. I wish you and yours all the best.

Your technical skills are amazing.I cheer for you.👍👍👍

I love the manual lathe operation

Protip: sharpie dot on the collet face lined up with the keyway

Thank you for another great video. Stay safe out there. Cheers

Much better CNC content, including the Fusion workflow too. Finally useful CNC content from Abom. However, I can't help but feel that the 5C collet arrangement is not conducive to accuracy and an actual 5C chuck would be a better solution

I first witnessed CNC in a production environment at Hayes-Dana in St. Catherines Ontario in 1985, almost 40 years ago. It was impressive then and the developments that have occurred so that this technology is available to smaller outfits is just as impressive.

Funniest thing I saw this year so far... Keep it up :)

looking good man

18:55 a little trick I used to keep track of the collects key ways is I’d put a dot on the face with a paint marker or dykem in a pinch. It saved time when i did some projects with collets and blocks and more drill press then probably makes sense.

love it

Neat little video. Relatively simple but non-trivial things like this are a brilliant way to learn new things. I've been doing similar stuff with FreeCAD for 3D printing stuff.

love your channel adam. i watch every episode. i am a former machinist, so very interesting to me.

26:27 all you had to do is move your G54 Z another .01 towards the chucl and rerun the program.

Last time I was in Florida it snowed in Coconut Key. That weekend the flamingos were shivering in Orlando and I bought a sweater, no coats were available.

47 below at my house. 20 above is speedo weather.

nice to see you coming along with the Fusion 360 and running that cnc machine. Maybe a mark on the face of the collet where the key is would help from fiddling around to find the key slot. Just a thought...

Beyond amazing! Yeeeeoooow!

Abom79 you made it right.

Hi .Look into the code for the line which has the finish pass on the section that was tapered. Subtract from the X statement the over size amount at the start at that point, and add an X statement of the corect diamenter at the end of the Z move. I've used trick many times to avoid using the tail stock. good luck!

Adam...another great video on making some CNC chips. BTW..Kevin over at MechanicalAdvantage has a new video series started where he is making a small engine by first modeling up the parts in F360, then showing how to take each part through the CAM processes, and then taking the Gcode out the machine and fabricating the parts, its been a great couple of sessions so far.

I need that 5c collet adapter.. cool something I can add to my tool box..

I spend a lot of time figuring out Fusion 360, and I'm someone who was a professional on Autodesk some 30 years ago. You're doing great!

Super interesting watching you learn.

Nice work Adam. And awesome that you’re learning fusion 360. Just wait until you get in parametric design. Would have made it much faster to change that hub length. Ask your online teacher guy about setting parameters.

Adam a machinist taught me to use cigarette papers (for roll your owns) to locate tools part surfaces.

You were talking about how cold it is up north I live in Bettendorf Iowa and it’s cold not right now, but it was. It was so cold the postman wasn’t delivering mail for almost a week.

It's funny how a small change in latitude makes a pretty big difference in temperature. I'm in the Ocala, FL area, we're about 95 miles due south of your latitude. I took the latitude on Google maps of your shop and moved east to directly north of me and measured the distance. It rarely goes below 30F here, maybe two or three time a year. And then only a couple of degrees, lowest temp so far this year was 29F.

Adam put a Sharpie mark on the collet to facilitate getting the collet located in the chuck.

Kevin is excellent. It would also be very much worth your time to work your way through the titans of cnc building blocks, even if you just do it in software space. Seat time is key with this - once you learn the interface and what strategies to leverage for different opps things get a lot easier

Darn 4th on the list😮

I can think of a couple of ways to remedy the deflection and taper on the second op. This may be something to raise with Kevin for future training.

I was wondering how the precision Mathews was working out? I am considering buying one. You are the only person I have seen with one. Love the channel by the way!!

Really looking forward to more videos on the Hardtail Vise finishing.

We have a plastic injection mold shop in town that keeps their shop conditioned at a set temperature all year long 24x7 to keep their materials and machines accurate. I'm unsure what temp they use but its likely in the middle to low 70's.

With the amount that you faced off the duff shaft on op2 you could have easily recovered it by doing op1 again with a different Z offset.

@9:56. .005" left on the face is more than enough for the finish tool to clean up. You most likely had a mismatch in the tool touchoffs of Z between the rough tool and finish tool. .003" or .004 difference between the two tools.

On those collets I like to mark the face in line with the keyway to make it easier to line up. Little black marker mark for example. Also judging by the placement of that machine in your shop I take it you don't plan on installing a bar feeder on this machine?

Hay Adamwhy don’t ya put a mark on the 5c collet face ta show ya where the key slot is on it jus a thought so ya don’t have ta fight ta find it

20 degrees (-6 C) in Florida ! Really ? I didn't know that was even possible ! Actually, we got 32 (0 C, in Montreal. Yes sir ! It's actually warmer in Montreal than in Florida. Incredible but true. Did you got snow ? Continue to produce your excellent and instructable videos man ! Hope you can heat in your shop. :-)

😊😊😊😊😊

CNC is the way to go, even for one-off parts. Once you have the conversational programming down and you trust your skills it’s a game changer.

when looking into the chip tray between the ways (eg. 23:38), you can see orange paint. is that the primer?

good stuff!! wash rinse repeat whatever you have to for your learning style...I'm learning 3D Blender via "Artisans of Vaul" YTC (can't be dependent on an internet connection--regardless how good it might be $$$) or else fussin 36Z would be it!! continue to do your thing; we'll revel in your determination, failures, and success!

Maybe you could put a mark on the end of the collet to help align the set screw when inserting the new tool into the collet housing?

It cracks me up when a machinist uses a crescent wrench

Could this be done as 1 op with tail stock support m

Is it possible on your machine to face, centre drill the bar end. Then pull the stock out to a live centre, then machine the whole shaft complete in one setting?

If you don't like your finish on a few of the parts, Chuck them up in the lathe and hold your precision ground stones to the part while it turning.

Put a Sharpie mark on the face of the collet so you know were the key way is.

Nice Work, but to make fusion easier, buy : the SpaceMouse Pro from 3Dconnexion (the Pro, not that small thing), put it on the left on your keyboard, keep the normal mouse on the right. I use a MX-master3 normal mouse from Logi. I was first sceptic about this, but now I cannot live without it.

Where can I purchase one of those 5C holders for my lathe?

Adam, couldn't you use the collect wrench to hold the collet when installing and removing the collet stop? Or would it damage the collet?

Is the vise completed? Did I miss something? I haven't seen it all assembled yet. An excellent series!! I machined for nearly 40 years and that was great entertainment for me. I enjoyed working on really big stuff built into even larger assemblies.

Hello friend, thank you for the super review, I will always look at your review, good luck my friend

Hello Adam, How is it possible that there is a visible pendulum ( runout ) at 30:20 Even though the first operation was also done in a collet.

Instead of using a stop in the collet, could one have the machine use that indicator to determine the position of the work piece and use that to get the operation done right?

Regarding OP#1, is it possible to cut your stock 1/8 inch long and add two or three roughing passes at the beginning of OP#1 that will either begin to make the first pass to face the stock or face nothing but air and then on the second or third face actually face the stock? This would eliminate you having to manually Z the face before beginning OP#1. In addition, adjust the stock length in OP#1 to allow the same beginning face methods at the beginning of OP#2. Of course I've never operated a CNC before but for the few seconds it takes to run two or three extra facing moves surely won't add up to the same amount of time it takes to manually Z the face as well as adding a safeguard that your stock isn't cut at an angle during the start of OP#2 which might cause you to have a saw cut remaining at the completion of OP#2. And, you're not wasting that much material by adding multiple passes to face the stock. This suggestion would only be useful for multiple parts production, not for a single part production.

.....................👍

Can I get a link for this collet Chuck?❤

Tuck those tools in son, they might get hung up on a trip wire.

Obligatory algorithm boost 👍👍

Yeah thats the thing with CNC. Setup takes a long time especially if you are still learning. Once youve done it ypu can knock out a lot of parts quickly. For small quantities oftentimes manual is faster

Maybe this I a dumb question but why doesn’t the lathe have a measurement tool similar to your Cnc mill?

Setting zero the way you did for op 1 make sure you set zero on the shortest piece. Nice work!!

Adam, I've been watching your channel for a long time. I enjoy watching all of the manual machining and watching you run all the different machines you have. I appreciate that you are learning to use CNC machines. But for me personally, I don't want to watch it. There are lots of CNC channels out there. Would you consider starting a separate channel for the CNC work? I'm sure there are many people out there that feel the same way. I'm not criticizing, just expressing the desire to watch you machine things manually. Thanks.

The second one didnt seem to chatter as much like the first cut wasnt as deep ???

You need to get more collect stops so you don't have to switch them out between collets. I have several for just that reason.

8 years as a cnc lathe operator theres no end to the issues that can happen! my latest aggravation is getting the programmers to understand the issues that are slowing down production! our programmers cannot run the machines!!

I don't see Abby in her maker space

I would not hold the precision 5c holder in hard jaws. I would not hold raw stock in a precision collet either. The finish tool should face the end to keep the distance to the shoulder accurate. Several facing cuts on op 1 will allow greater tolerance when sawing the blanks. Sorry no cnc tips just basic stuff.

бедные американские токаря и фрезеровшики с этими дюймовыми размерами. это же просто сумашествие!

I much preferred the pre-CNC Abom ...

Finish tool should finish face.

I fully understand the need to move to CNC for his business, and I’ll certainly keep watching. But… as someone who drove a computer for my career, I find it about as entertaining as watching paint dry to watch. Not my channel, and he SHOULD do what he wants. I subscribed and supported a machining channel… I miss it. I’ve truly enjoyed the vice machining, at least those where manual machining is being used. I will still watch this channel, but I’m looking for another manual machining channel. Obviously my opinion and I wish Adam every success.

For the life of me, I can't appreciate cnc for a small shop. Price of the machine, time in programming, waste of stock from misprogramming, crashed tools, and the learning curve of screwy/fickle software. I can appreciate the drive to gain knowledge in new current processes. In MY OPINION, it's the difference between Empire Strikes Back and Clone Wars. Nothing beats old school machining skills.

😛😛😛😛😛😛😛❤❤❤❤❤❤👍👍👍👍👍👍👍👍👍

You really need CAD/CAM for such a simple part?

To be honest this job would be just as quick on a manual machines.

sorry can't get into the cnc stuff; its just boring watching a computer run the job.

You can always tell the shop that has a CNC setup……..they add a zero to the actual cost of the job.

Missing some of the shut up just working videos.

CNC… Eh nah, boring.

When's the collaboration with TitansOfCNC coming ? @titansofcnc
