dmg dmc105v tnc530 fixture offset

[jelmerra]

Hi I am programming post processors and encountered a challenge with this machine. This is a five axis machine with b-axis (head) and c-axis(table).

The postprocessor drives a machine model in the cad/cam system. I used the center of the table as reference in my machine model. When they put an actual part on the real machine the part is not exactly the same way positioned i.e. the part is translated.

I intended to have the nc-program cope with this offset. When I have a combination of b and c the spatial plane function does the job properly. However, if I only have a c-axis rotation I cannot seem to get it to work. The program below is one of my test programs. It is a block from which one edge is milled under different orientations 0 90 180 270 and two debur paths. This does not work according to the operator hopefully somebody is willing to share how to solve this challenge.

Thanks,

Jelmer
