the post process editing trick just blew my fuckin mind, 3 years of watching your videos and I keep learning new things

I've made lots of triple clamps over the years on my machines...you certainly did it the hard way using the fourth axis. You could have done 90% of it flat in a vise with a more rigid set-up and next to zero clearance issues.

finally a BAD ass NYC CNC video! Great work guys!

Much of that can also be done with a square collet holder in a vise. For the poor amongst us that only have three axis.

Very cool setup! I like the riser block to get your clearance. You really had to work to get this right but it's great to be able to show just what you can do with these machines. Hope all is well! - Tom Z

Chapters! Thanks for this awesome video. I really appreciate how in depth the detail is. -Ken

Nice job young man, a pleasure to watch!

Excellent work lads! much appreciated, using the 4th axis in that manner is something i wouldnt have tried! ;-)

You guys make it look easy! Great work!

Awesome content, loved it. Very helpful as I'm getting my first 4th axis soon!

It must be the season for it! I've done a bunch of triple clamps lately!

Nice result. Well done!

Next time instead of machining the boss on your stock try making that a separate piece, machine the last opp first to prep your stock, and bolt the fixture into your stock.

Great project. Very well presented.. Keep up the good work.

I done a few of these on my manual bridgeport 30 years ago before the mass cnc explosion. I think back then it was just in mass production cycles. Now i hope your helicoiling the threads

Well done 👍🏼

Brilliant video I make a lot yokes as we call them in the uk 🇬🇧 and they are a multiple opp part

Great video!

That was awesome to watch! If this were a large batch of parts to run I would take a double cut 45 degree saw to chamfer the saw cut slot that goes thru to the fork tube bore, and a regular chamfer tool to chamfer both top and bottom of saw cut. Then if you have enough tool stations, fashion a special tool to maybe broach a 45 degree chamfer on the inside of the fork tube bore where the saw cut breaks thru. Or simply take an end mill that is already being used to machine the part and plunge straight down where the saw cut meets the fork tube bore just to take that sharp edge away if you don’t have the luxury to add that special tool. 🤷‍♂️ but then you would take the deburr guys job lol. This machine has limited tools though so in reality if you had one tool station available to put that 45 degree double cut saw you are golden.

This is a level 10 video for sure......Awesome job!

For Tormach/Pathpilot users, there’s no need to edit your post processor for use with Fusion 360. David Loomes at Xoomspeed.com has the post processor already done and available as a free download. He seems to keep this updated with each Pathpilot update, if needed, and adds new features from time to time.

Good job !

I have been working on a dragbike triple clamp and now can see how I can use our Haas 5C 4th axis to do this better I may machine a Hex and hold with a 5C Hex collet. thks

Crazy good!

Very nice!

Great video. In the slitting saw section, how do you get the saw to not retract in z after each pass?

WoW amazing dude this is awsome I want to get a tormach now a really really good video I wish I could like it twice I want to get a tormach right now but you could use the saw in the first operation instead of the 2d contour it will be a lot faster but you'll have to cut the rest in a second operation or you can use the dewalt saw or something else that isn't necessarly a cnc but nice job

I don't care about Tormach... what you speak of here is golden visdom for the ages. Oh, you have a super special crazy - bit tooo big - tool to be used on that one thing... Let the post processor, know...when you hit the tool number 999... go fetch...because its a special code, to get that crazy thing, standing beside the part, on the same table, you are machining.... THIS IS SOOOO GOLDEN!

very very good

Isn't it better to use slitting saws in one full depth pass and jus feed very slowly?

This seems a complex way to do it. For our machines (heidenhain)our post processor posts out a program call with a link to a custom "safe" program already saved in the machine that move the spindle and bc axis into a safe position in reference to the machines actual position (m91). It does this before and after the tool call and it allows the post processes to work with any different machine as each safe program is custom to the machine and the processor calls it. For example on some machines it'll move the spindle up and away, and then move the spindle along the back of the machine and then along the right hand side until it reaches the tool change position, going completely around the bed instead of across it. It also does this before the bc axis moves to put the tool in a safe place

Good job, need 3x more material on outer OD. It's the Most important part & takes massive forces and stretches, twists in every imaginable function.

How do you deal with preventing chatter with the large overhangs?

Hello, thanks for this great Video. Now my Old Fusion Heidenhain Post can auto saver etract bevor M06 Toolchange. I had too tweek every code from Fusion 1Year long! what a great help! Could you do a video how to do the same work as you shown in a video, but only using a manual dividing head with optinal stops, so i could crank the handle to the next 90/180 degree? I think it would help a lot of people with older machines without an output for 4th axis, or with old style Haas external indexer Controler. Thanks allot.

nice

I admire your braveness what type of clamping you chose. I suppose it take you a lot of machining time. We are doing more types of triple clamps in serie production so we have completely different setup. We have tight tolerances on the side holes for columns. Wasnt it problem in your case?

What is that ring on the bottom of the spindle for?

Oh c'mon...... You can't machine that hanging way out there like that. I can't imagine the CHATTER!!!!!!

Very nice. You can tell from my pic I approve of this video. Lol

Just curious what was the run time on this part?

Nice job.. but what was the real actual cycle time and the actual time it took sitting at the computer programming. For reference purposes it would be nice if total actual sitdown program times ( including trials and errors until right) and complete machine cycle times (including speed and feed adjustments time) were included or disclosed at the end of the videos just like you display and disclose final speeds and feeds information.

What's that black collar on the spindle for? Its not on a stock 100MX.

This is almost exactly the part I have planned for my PM PM728VT CNC mill

Excellent video, good to see NYC CNC still uploading to KZfaq unlike some that have stopped for some reason?...Does anyone know about why John Grimsmo- Grimsmo Knives has stopped uploading?...They have ghosted KZfaq a couple or three months ago saying they were "slammed" and there was heaps of content coming?... can anybody tell us what's up?

good

Flat track? You mean Speedway?

I wonder if, instead of using that slitting saw like a meat slider, you couldn't have just used it like a chop saw. Position it to the center of the boss and then just plunge straight in to finish depth. Seems it would have been a lot faster, and as long as the coolant is running the blade should have stayed cleared and cool enough.

Where is the Johnny 5 build? Thanks 👍

Why not use a face mill on op 1.

nicely done! but I can't stand how jeffrey is using his fusion window. don't you like some extra space with hiding the parts panel, or is it just my OCD? 😫

How long does it take to make one?

Total machining time?

A bit late to this party. Can you recall the total time elapsed for this part? -both machining and Fusion CAM design? Thanks much.

How much would a part like this cost for the client?

How’s Johnny 5 going?

I assume this 4th axis won't work with the Hobbyist Fusion 360 version anymore?

I feel that the whole point in tabbing is sometimes missed. If you are doing a second opp to remove the tabs and drill some holes anyway, why bother with all the tricky tool paths to tab when you can just hog away the boss and remaining material in the last op? The point in tabbing is a one and done part. If you need another op after the tabs, there's no point in tabbing, just leave the gripped material on the part and remove it in the last op just like you normally would when working in a vise with a 3 axis setup. If you can complete the part with only tabs remaining that get removed with a quick bump on a wheel, then you've saved an op and there was a point in doing it. Otherwise, no point in tabbing. I've seen grimsmo doing similar things. Dovetailing a part to put in the kern, tabbing it off, then grabbing the part for another opp to tidy up the finish where it was tabbed. What was the point? Leave the dovetail on the part and machine it off in the second op if you're doing a second op anyway

All that extra work and figuring out....makes me think that you would have been better off just doing it in separate ops. That's how we make our triple clamps.

You should have created a hex boss to hold the part.

I hope you treated your self to a sandwich or something while the CNC was doing it's thing. Amazing work!

Talk flat track and then show a Speedway bike?

first

I made these for Ducati 25 years ago , seems like a lot of unnecessary prep work for a simple part.

Niche is pronounced knee-sh, not n-itch. I know it is an uncommon word and not said often, but I hope it helps if you use it a party or something (once we can have parties again).
