I'm new at setting the trunion up we purchased recently a TR 160. The only issue I'm have is finding the center of rotation. I feel I can produce a good program, once I have this number. Here is the information I have so far but its not helping me find the number yet.
We have 2 Jergens Plates at 1.375 each.
a 60mm Jergens Vise
and a pivot of 0.127
Thank you for any help.

TR 160 TRUNION FIRST SETUP, NEED HELP WITH CENTER OF ROTATION

Hey Robert
Here is the math we have came up with for the stack up.
-.127 (Pivot)
2.750 (Plates)
3.691 (Bottom of vise to top of edge stock will sit on)
2.500 (material)
= 8.814
So I have Mastercam setup as the WCS is
X0 = center of the Material
y0 = center of the Material
Z0 = -8.814 from top of material down.
So when we run the little program I made to rotate B0 A90 degrees and mill -0.015 and rotate B0 A180 and mill another -0.15 step. We had a problem the first side was -.290 off. we drop Z -.290 and it skim about -0.015 off B0 A90 but wanted to dig in ALOT on B0 A180. So I guess my question is does the machinist touch the top of the material and drop is -8.814 to match what I have on Mastercam or I'm I missing something. Thank you so much for all your help.
Cheers
Shawn
