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.

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 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

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 only took one endmill for all the parts.

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.

Yes the endmill just touched the soft jaws.

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

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.

ansys spaceclaim dosen't make gcode you can't program parts with it, he is using spaceclaim for geometry modeling and esprit cam programming.

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!

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. 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.

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.

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.

from a response Edge Precision gave elsewhere: "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."
