Sacrificial Fixture

[@erikjgreen]

Every time I start to feel proud that I'm getting the hang of CNC machining steel parts to order I watch one of your videos and all my humility comes back :)

[@chrisread3450]

The 3D CAD of the finished part you showed looks like a demo part developed by a CAD software company to showcase all of the crazy features you can create. Definitely a case of “if I can draw it, therefore it can be made”. Great work as always Peter, you keep setting the bar higher and surpassing yourself.

@@EdgePrecision in a similar vein, I had a guy ask me what took so long. I was trouble - shooting a pre-existing office telephone system to figure out what lines I might be able to reuse on the new system I was installing. Some lines went about a quarter of a mile to another building on the ranch. Anyway, he summed it all up by saying, it's just a bunch of wires, I don't see the problem.......

Love the magnet holding the parallel. Why didn't I think of that? Struggled for years with a manual lathe, wishing I had 3 hands.

[@smithparkins4862]

A suggestion. You could jog the tool in without the part in place (Using the readout to get close), then slide the part in, indexing to the slot. This would help with the fiddling about. Rinse then repeat.....

[@amartinez9390]

Your talents are unmatchable in my HUMBLE opinion. I once had a housing out of aluminum tubing that had a .004 tolerance on the thickness. I used a split arbor that I pinned together to hold the tolerance. This reminded me of that project. They actually used it to do the milling operations needed on the part. Just a suggestion, a spring loaded pin may reduce the risk of bottoming out the pin to the part.

Thanks Peter, yet another interesting video with a lot insight. Much appreciated.

[@billdlv]

Good idea with the magnet holding the parallel. I would not have thought about making the slug out of a similar material as the part to make sure the drill is loaded the same. Those ports have a lot of features...I imagine they have a pretty tight surface finish callout too.

Great video peter!! Thank you!

[@chrisyboy666]

Your without a doubt one if not the best engineers I’ve came across,considering I’ve been on the Apps for some of the biggest and so called best machine tool builders out there I’ve worked for Mazak served my apprenticeship their,Also worked for Maho/mattsurra and a few others...not blowing anime up your arse in just a simple fact you are in that top 5% of engineers I’ve came across and worked with over the years I’m based in the UK yeah I’m English...but I’ve worked all over the world and your videos and how you approach and execute your work always amazes me...a natural engineer.....Back to my point do you ever think of upgrading and updating the Mazak for a newer model ?? Judging by the complex nature of the work you , @ what point would you say the Mazak has done its job and what would your next machine be if cost was totally irrelevant...The nature of your work you couldn’t go out and by a HAAS UMC it would simply not be up to the job...what would your dream machine be...totally pointless question really,just interested to know what machine you would go for if you had to go out and purchase a machine tomorrow part 1 of money was no object part 2 if you were looking for value for money and price was important...totally irrelevant questions..I’m just purely interested in what you would look for and what machine that would be ...thanks Peter respect from the UK to man that has mastered his craft... P/s I’ve done a rough calculation what I would charge or what I’d recommend the charge would be the last tmachine tool company I worked for that made millturns (Okuma ) Thats a direct comparable to the integrex say the job was a run of 20 I would charge £400k or if it was a 1 off part the single unit price would be 31k that’s uk £ Stirling am I close ?? I’ve worked this from price based from 2 years ago can’t do a direct comparison as I’m @ Makino and they don’t produce a direct comparable machine.

[@EdgePrecision]

Carlos, First, thank you! You know its been so long sense I have been in the market for a machine that I don't know about the new models and whats available. I do, for my style of work like the B axis mill turn type of machine. This Mazak is a good machine and I like it. The short comings of this type of machine (Or mine) is. If you are doing large turning type of parts requiring large boring bars. This machines limit to tool changer length is a 19.50" long tool. Now there is a Big Bar option that's mounts large bars from a stoker above the tail stock. It mounts the bar on the bottom of the Y axis (Not in the milling spindle). This is able to mount 3 bars as long as 1 meter in length. and can automatically change the tips if necessary from the tool changer. That would be nice. I would also like a longer bed (Mine is 120"). A U axis would also be very handy for the type of work I do. I would also get the biggest magazine capacity possible. At least 120 tools (Mine is 80) and Capto 10 if possible (mine is C8). This machine would also be much better if it had more X minus travel (It only has X-10mm). This makes doing facing cuts in the bottom of large bores with large bars to small diameters not possible. Those would be my wishes if possible.

[@chrisyboy666]

Edge Precision thanks for the reply excuse the punctuation and terrible grammar...it was wrote in 3 mins on an iPhone 📲 was I close with the pricing ?? I understand if you don’t want to let the cat out of the...bag competition is fierce out their...I personally can’t see how you could do the job any cheaper,considering the tooling required etc etc.. we quote a 6 month lead time @ least on a job like this...we generally only use 1 tooling provider as a rule usually sandvik or seco OEM prefer it that way your not so constrained in that dept I guess ? Just simplify the supply chain for the end user

[@EdgePrecision]

I will just say this. The parts are worth more than you suggest in your comment.

[@hinz1]

Wouldn't boring the hole somewhat solve the issue with drill deflection? Like do 1/10mm undersize hole with circular interpolation and finalize it with a single point boring tool and very small feed rate?

[@63256325N]

Well thought out and explained, thanks.

[@flagmedownmedia]

Heya, Watching you creating the jigs to slove a problem is is most better than watching the machining of the main part :) Can I ask a qeuestion however it might of been asked already been asked, or you would of already thought of this; You have your own tool grinder, you could of ground your own endmill to do the job? Regards

[@bcbloc02]

I guess you figure it may try to twist in the bore while drilling why you keyed the slugs?

Yes, can’t be to carful.

[@number40Fan]

The key is just a reference when milling the other end of the slug. But, the slug twisting in the bore probably won't happen, if very little.

Great video as always, with the chuck in a chuck, what max RPM? I was listening to in wind up hoping you were not stood in line with it. Not that I know anything, but would be cool to hear what you wind it up to

[@EdgePrecision]

Thanks Andrew. The max speed of the turning spindle is 1600 rpm. It isn’t possible on this machine to run any of the spindles with the doors open. They also have bullet proof glass on their windows. So standing in line with the turning spindle is really a issue. I think if I remember correctly I had the speed in this program limited to 1000 rpm.

Do you think it would have problems if you had used regular cheap 1018?

[@scottr939]

I know Peter says he doesn't know what the final part is used for, but can anyone guess a general idea? I've never seen such a complex thing. Maybe some kind of valving for a crazy engine? And titanium because of - weight, corrosion resistance?

[@kabassik1900]

Hi. Thanks for sharing your experience. Sorry for stupid question. Why you need same orientation two slots on faces?

[@Jay9999]

Super cool Master jedi

[@TommiHonkonen]

Wonder if you used long extension for facemill and used that to helical the bore near the cross holes.

[@EdgePrecision]

These holes are more than 16" down a 1.496 diameter hole. The tool would be to long. Also and more importantly the drawing doesn't show it being done that way. They also have a .020 corner radius where the holes break into the large hole. I will let the deburr guys figure out how to do that.

[@crashfactory]

Would it be easier to locate the part if the slot exited the face with a small v-shaped mouth? Could get the gauge pin at the right high, jog it toward the loose part, and have it rotate the part ideally for your alignment.

[@EdgePrecision]

Yes that could work.

[@jamesg2987]

When you machined the long water hardened drill rod how did you align the features on either end? I don't see any slots ? Cheers in advance James

I like the way you think! :)

[@micahhunter2706]

That slot you milled for indication is what I call a witness. Don't you think it's ridiculous that they modeled it with the drills going so deep. I'd like to know what the reason was for.

[@kyleherald2394]

Why did the 2 face slots in the drill fixture have to be exactly in the same orientation. When they are 1 time use.

[@arnljotseem8794]

So clever!!

[@bronzesledgehammer]

Or maybe you can mill a cross pattern keyway on that drill guide and use it twice rather than a one-off?

[@Thomas_Lemmey]

Nicely done! Was it possible to turn the piece 90 degrees and use again or do the drilled holes go too deep and leave not enough metal?

[@EdgePrecision]

I did look at that but there isn’t enough material. Or to put it another way the notches from the holes cover more than 90 degrees of the hole.

Hey, I hope that you are still making videos of the actual parts that you are making, so that when you retire, you can start posting them once no one cares anymore and you live in Mexico! Lol

[@multiHappyHacker]

So I've got a question you can probably answer. I bought a used live tool lathe with a Y axis, hydraulic chuck, etc. It came with a 2 foot tall roll around white box that says "automatic oil temperature regulator", is that for the hydraulics, way oil, or was the company perhaps using it to keep the coolant cold? imgur.com/GDyrCJa Cold coolant would keep the live tool blocks lasting longer.

[@EdgePrecision]

It appears to be a chiller unit. It would be for the hydraulic oil or on lathes they often have a spindle oil/gearbox system and these are used to cool the spindle oil. Is there not someone that disassembled this machine that could tell you?

[@multiHappyHacker]

@@EdgePrecision lol the place that sold the machine almost won't tell me who sold it. Resell CNC, some great deals before the end of year. There's a tag on it that says to me it's from a custom bicycle shop that I could call, but it's probably a real industrial shop and finding the right guy would be hard.

[@koryputnam5816]

Hey Peter i haven't run a ton of titanium so I was wondering if 1000 RPM is always your max or do you run it faster depending on tooling? And as you were cutting that part off what was your RPM starting at? You are awesome at what you do, i hope to be as skilled aa you some day!

[@johnshaw8013]

When roughly aligned by eye... Why not come down say 1mm above bottom of alignment slot at +5mm Z, with the part loosely gripped and them jog in on Z... the part will align itself as the round peg goes up the square slot.

[@henrychan720]

Dumb question, why not just plunge/spiral in with an endmill, and finish the bore with a ball/tapered endmill running in simultaneous 5 axis for tool collision avoidance if higher accuracy is needed?

[@danielmachado6750]

🇧🇷Daniel Machado - Brazil🌎

[@peter-basschelling6695]

Seems like the designer could have made your life a lot easier by just having the tangent holes up to the big bore instead of drilling it passed the bore. There might be a reason for that but it's always fun to see that no matter how strange the part is designed, a good machinist can make it one way or another. Even though some more thought in the design could have saved a lot of time (and money i guess)

[@nzjdmsti]

Looks to be for some kind of retaining pin to me.

[@DelynKeun]

Agree look to possibly be retaining pins to hold and orient a part goes in that bore. To the machinists, assuming that, what would you suggest to change to the design for manufacturing? See if you can have them alter the blank that gets to EDGE so the 1.4" bore stops before these cross holes to leave material so the drill doesn't deflect and finish the center bore and depth after those cross holes? Or something else to simplify?

[@jeffren70]

Peter, you might know by now, but will this stick in the bore once you drill into it and there is a burr where you cross drill it?

[@EdgePrecision]

It will get a little tighter but I will be able to get it out with a slide hammer if necessary. I think when it moves a little way it will flatten down any small burrs.

[@DonStinger]

Hi Peter, I may have missed something. Was it really necessary to orient the two slots on the sacrificial part to one another? Great video as always!

[@EdgePrecision]

look at my answer to the previous comment. He asked the same thing.

[@mackk123]

Why not come down with an endmill instead of a drill for those two interrupted holes?

[@EdgePrecision]

The Idea of this test part was to simulate whats going to happen on the real part. Also a endmill wont leave a good enough finish (I tried it). No matter how you mill it there is always some sort of marks left by milling. I also tried using a boring head. But that gave trouble with the cross intersecting hole. These .218 holes are already drilled lengthwise in the parts before I get them. In the real parts I drilled the hole than roughed milled than used the form tool I showed in this video.

[@rav5383]

What CAD software are you using?

[@EdgePrecision]

The cad software I use is called SpaceClaim.

[@waleedmohamad9660]

What is the spindle speed that u used for parting off

[@EdgePrecision]

Its a constant surface speed. I think if I remember correct it was 150 SFM at .002 feed per revolution.

[@SuperAWaC]

does the gauge pin have through spindle coolant? ;)

[@somebodyelse6673]

Likely through collet coolant, dripping down the pin

[@ajaym2169]

Two hole cut with endmill Is possible?

[@EdgePrecision]

I won’t say it’s impossible but the holes are .255 in diameter. So to mill them would take a smaller tool than that. They go about 2” deep and intersect that larger hole. This would be a difficult milling operation to do without getting deflection and holding the tolerance on location and diameter. The drawing also shows a drill point at the bottom. I’m not sure if that’s necessary or not.
