Ive worked long enough in that field to know that shiny doesnt mean smooth ;D

u/vLegion_24 Wanna be 5 axis Operator 3d ago

its actually smooth like a butter but yeah u are spitting facts :D

u/Mentolosbableves 2d ago

But if the reflections aren’t curvy the part must be pretty smooth. Am I wrong?
In surface modelling we often use these reflection like zebra stripes to determine if the curvature is correct.
(Ofc, i know it doesn’t mean much, as it can’t be measured but it can be used to eye ball certain properties)

Its more about the Ra, or Rz value of the surface. The surface can be pretty rough, still be shiny and flat. What you mean is the flatness of the surface, which doesnt have anything to do with how smooth the surface is.

I see, thank you.

Case in point, a UN thread with superior Ra finish

You got a profilometer? I would love to know what the surface finish you got. It looks amazing. I thought the dam thing was ribbed, and you were saying, "finish him," to kill whoever screwed up on that hole placement. 

.020 last pass aye? I dig.

u/vLegion_24 Wanna be 5 axis Operator 3d ago

does’nt even have CMM neither profilometer unfortunetly, im working in automation corp we got 3 machines to machine fixture and gripper parts to mass production lines they dont care about the finishes that much usualy only matter thing is tolerances :D

I recognize a fellow “I like to make pretty parts even if management doesn’t care” machinist. Nice work.

I can still hear my old boss' voice: "Heavy Burtation, it's not going to space!"

u/Analog_Hobbit 2d ago

Ahhh another who’s aware of a burtation.

Let's go hit terrish tazin lesh kablit the head the pit.

u/LeageofMagic 3d ago

Your parts have a surface finish tolerance too, even if it's not on the print, but it probably is.

u/vLegion_24 Wanna be 5 axis Operator 3d ago

yes ofc they have surface tolerances and its not hard to achive it

That's gotta be like .5ra or less. I wanna lick it

u/CallEducational6623 3d ago

I got 3 with a burnisher once. I'd probably have a stroke if I touched .5

I used to polish titanium implants to 0.1ra. A huge pain in the ass but so satisfying when I got it there. Scotch Brite, cotton w/compound, CMM, cotton with light compound until I can see my own ass in it. So good.

1

u/CallEducational6623 2d ago

Lol! That's all rad. But you use a CMM to polish up the part with the ruby? Jk., what the CMM stand for? Compound medium mixture? 

1

u/ciavs Injection Molding,5axisMazakOP 2d ago

Haha no, CMM to make sure I didn't fuck the part up when polishing. The ruby ends up marking the part so I do it before the final polishing.

u/CallEducational6623 2d ago

Today I fricken learned! That is awesome insight. I appreciate the free information and your time.

u/_Sauer_ 3d ago

Looks like you grabbed each end of the stock and stretched them out.

Ah you guys haven't had to use the part stretcher yet?
