Origin or Stock to Leave?

[EazyE]

What do you do? - When setting up a origin say for machining the Top side of a part while the overall height is still +.050 and Z is set to bottom of vise or fixture do you put all toolpaths at Stock Z+.050 or just create the origin +.050 from actual Z0 and use the actual Z positions..

I use real Z's. probably your first op is to face off that .05 correct?

Lanart - No the bottom side is to machined as the second side. the block has not been squared so machining the top to +.050 and milling say a pocket in it then flipping the part and maching the .050 off bringing the height to print and having square faces...

[lanart]

ohh, I would still have Z0 and origin very bottom.

then I would have tool paths take into account that extra .05 If your stock is say 1.00 and your pocket is .12 deep I put in that the depth of pocket is 1.0-.12 or .88
