If you were to tell me that these end up in a theme park somewhere, I wouldn't be surprised. Often an oddly confused collection of "we don't know why" for art and "we won't say why" for propriety. I confess to being on both sides of those equations over time. It is truly a delight when a machinist can infer the intent and look past the omissions in drawings to come up with the correct result. Definitely an indication of your talent! (And yes, I've seen exotics go into parks for no valid reason...sad use of the material, IMHO)
I’m glad you still do this, you always impress me with the jobs that are a great example of how tool makers are far far more important to have in the world than a lot of companies would have you believe.
I am quite impressed with myself. I saw the model you showed and imagined in my head how I would do it with your machine and then it cut to you doing it exactly as I imagined. I don’t even run a 5 axis.
I do that all the time sometimes I'll pause the video and start planing the operations in my head, it is the closest thing to practice guys like us have
I agree, I do the same thing, deciding what to do next and when the video presenter does what I thought, I feel as if I am doing the job....and it gives me confidence in my abilities...Paul in Florida ...@@merouanebenderradji1582
Video ideas for you: 1. story behind how you came to own the Star Tool Grinder. Crazy that you own 1 of 3.' '2. Stories about your early machining career. Someone in a comment said you made stuff for NASA I think. Probably some interesting things about how you developed your skills.
Both good ideas Thanks! I do have some more videos on the grinder. There is a playlist called Star Grinder. I may have discussed that in one of the videos. I cant remember. Also on my channel there is a video called Shop Tour . Again I cant remember but I may have talked about how I started in that video.
It took some serious dedication to the job to walk away from a complicated solution like that hobbing tool. I think the lesson for me was that no matter how far down a path you go, you always need to be willing to rethink your plan.
I probably would have taken a sharp radius turning tool and ran a fast feed rate, almost like a thread, across the face. Rings for pipe fittings use that technique a lot to grip the gaskets they use.
Yours looks pretty good! Did you touch that jaw with the cutter? Looks like fine nibbles! Presumably the knurl is there to allow hand tightening. Had I just specified "a knurl" I would have been happy with a 1/16 end mill cutting cross hatches by touching it sideways I think.
One pass for each knurl? Did the endmill last long? Monel is tough to machine with general carbide tools, and I remember my tools never liked bigger cuts in it
I would say that you should angle the lines, then run it again but angling the lines go the other way to make a cross hatch, you could do it with a subprogram, but that would be pretty boring for 58 parts!😂 Set it up on a helper's machine.
last i did something like this, i made a stamp/die rather than actually run it in the cnc (had enough parts to justify making it) in my case, it was literally just a manager wanting there to be knurling there.
The actual milling only took around 4.5 minutes. But my cam software puts in all these clamp and unclamp codes on the rotary C and B axis so that adds to the cycle time a little. I guess it would have been worthwhile to edit them out of the program. With this little cutting it really isn’t necessary to clamp them.
@@joshuawentworth7426 Yes I did. I did select to not clamp the C axis but not the B axis. I assumed it would not put the commands for the B axis. But for some reason it rotates the work plane and then canceles it for every line. It doesn’t actually move the B axis. But it puts in the clamp and unclamp M codes around the work plane rotate rotate (G68) line. It really doesn’t need to rotate the work plane but once at the beginning. Because it doesn’t change for the whole tool.
Wouldn't it have been possible to use your "home made" hobbing tool and use the mazak like a shaper (similar like you made the corners of the hardy hole in the anvil)? Of course it would be a straight serrations "knurl" too...
I'm guessing the surface rotates on another metal part, the knurl is to hold oil or grease. With such a small cutter I would think the life span would be short. De burring would be vary important and might be a bit of a pin on that hard of metal if you had to do it.

This part is a piston for a telescoping cylinder. If I had to speculate I would say. When the piston is fully extended against this shoulder. There is a certain amount of surface tension/break away force in the oil that stops the faces from parting when the pistons retract. These little slots reduce that.
Thanks! But yes obviously not a knurling. The print called what they wanted on this face straight knurl. Hence the name Is It A Knurl? But it’s a little impractical to put a knurl this close to an OD. It would require some very special tooling for only a few parts. So we did it this way and the customer bought it.
Perhaps you want a mini shaper attatchment with Capto cone for such tasks? Shouldn't be too difficult to build, with the machines and capabilities you have ;-D Perhaps similar to those, with tool retractiion, as no chip relief is required there. ua-cam.com/video/7klunkuScXs/v-deo.html
That’s a very interesting machine in that video. All that isn’t necessary on this machine. You need to watch my videos on where I did snapping with this machine. On a CNC machine you can just program the movements without rotating the milling spindle. Look at my videos on making the Anvils. In them I shape the square hardy holes.
On the one hand, it's nice the designer wasn't too fussy about the "knurl" pattern. On the other more wtf hand is it really necessary at all?!? I'd be very interested in the application that made that feature critical.

It's always better when an engineer is willing to work with you not just demanding you make it happen their way.
Somewhere an engineer and an accountant are staring at one another trying to figure who gets to explain the bill to the boss. 😅
I would 100% put separate lines on the bill for the "knurling", even separating out the cad/cam time and machine time just for the that op x48.

thank you Peter! your demeanor alone teaches me so much
Love it when the back and forth on the design works out for the better!
Ur the man!Top notch machinist!
Great video and great close ups 👌 thanks for sharing 👍
Total artistry!
Awesome job.
Simple and elegant solution, with great results. A-1.
First from UK, Hi Peter. just so good a fix you clever old stick
It took some serious dedication to the job to walk away from a complicated solution like that hobbing tool. I think the lesson for me was that no matter how far down a path you go, you always need to be willing to rethink your plan.
Always interesting. Thank you sir.
You weren't kidding about the nice finish on those though 😀
My first thought was to do the same thing with a pantograph type cutter making serrations very similar to a knurl!
I probably would have taken a sharp radius turning tool and ran a fast feed rate, almost like a thread, across the face. Rings for pipe fittings use that technique a lot to grip the gaskets they use.
nice solution to a real problem.
Yours looks pretty good!

Presumably the knurl is there to allow hand tightening.
Had I just specified "a knurl" I would have been happy with a 1/16 end mill cutting cross hatches by touching it sideways I think.
Yes the endmill just touched the soft jaws.
One pass for each knurl? Did the endmill last long? Monel is tough to machine with general carbide tools, and I remember my tools never liked bigger cuts in it
It only took one endmill for all the parts.
I would say that you should angle the lines, then run it again but angling the lines go the other way to make a cross hatch, you could do it with a subprogram, but that would be pretty boring for 58 parts!😂 Set it up on a helper's machine.
They didn’t want a crosshatch pattern.

hello peter,,,good video
Which software use for mazak integrex model.
👍
Machining magician.
I wish you had shown the "hobbing" experiment.
Knurley Dude :)
or press down vertically onto custom knurl
edge precision boss did you have to accept any students for machining learning? I saw your integrex experience well boss
How long does an operation like that take per part?
The actual milling only took around 4.5 minutes. But my cam software puts in all these clamp and unclamp codes on the rotary C and B axis so that adds to the cycle time a little. I guess it would have been worthwhile to edit them out of the program. With this little cutting it really isn’t necessary to clamp them.
@@EdgePrecision Did you do this in esprit? I know how to get rid of all that I believe.
@@joshuawentworth7426 Yes I did. I did select to not clamp the C axis but not the B axis. I assumed it would not put the commands for the B axis.

Yes and that was my next idea if the milling wasn’t acceptable.
Buenos notches 😏

ansys spaceclaim dosen't make gcode you can't program parts with it, he is using spaceclaim for geometry modeling and esprit cam programming.
Hey you doing okay? Staying busy probably
Yes thank you! A lot has changed and there is a lot to talk about. I need to make a video to explain things. Thanks again!
There seems to be an ever increasing disconnect between the engineers designing parts and the machinist who have to produce them
Peter, the knurl is for oil lubrucation: like Hand-Scraping on a Way. You could do any kind of pattern that traps oil.
This part is a piston for a telescoping cylinder. If I had to speculate I would say. When the piston is fully extended against this shoulder. There is a certain amount of surface tension/break away force in the oil that stops the faces from parting when the pistons retract. These little slots reduce that.
Yes, I see. You are right.
Great machining, but it's not knurling. That involves the imprinting of a texture on the workpiece. Either way, NICE work.
Thanks! But yes obviously not a knurling. The print called what they wanted on this face straight knurl. Hence the name Is It A Knurl? But it’s a little impractical to put a knurl this close to an OD. It would require some very special tooling for only a few parts. So we did it this way and the customer bought it.

man that machine looked like from outer space basically a vertical shaper.

This is the piston of a telescopic cylinder not sure what the knurls are for.
