Hi, this is a off-topic question, but I'm sure someone here will be able to gibe a hint:
I'm trying to understand how to do the necessary coordinate transformations to transform local coordinates from an off-setted an rotated local coordinate system to the global coordinate system. Unfortunately I have to do these calculations sine the CNC does not support G92 an the related commands. I have the x, y, z offset and the A, B, C rotation of the local coordinate system, but I'm not sure how to rest these A, B, C angels. I tried to interpret them as roll, pitch, yaw as well as as simple rotations around the x, y, z-aces but non of my approaches seems to work. Can someone explain what A, B, C angles usually indicate in CAM? Does someone have the transformation matrix ready for that kind of problem? Does anyone have any suggestion where to find good explanation on the various kinds to express a rotation/direction in space an how they are used in CAM usually?
