Hello
I want to add a swivel head (B-axis? rotating around Y-axis) to one of my existing mills. The machine is a typical 3-axis with a typical rotary that rotates around X. The machine runs on Fanuc-type gcode and in this configuration it will be very simple in m-codes, just spindle start, stop and coolant, not even tool change, but i do need it to do 5ax contouring. Controller does not support TCP.
I have configured the kinematics on the setup menu and on a simple block with holes at an angle, i do get a correct output using one of the Doosan post-processors, meaning that the A and B angles are correct.
The question now is, how do i handle tool length offset? More specifically, how do i set it up so that it compensates for B-axis movements? Presumably i need to know what the distance is from the center of rotation of the B axis to the tip of the tool, because the longer the distance, the bigger the interpolated XZ move will have to be to follow a radius. But is this something that is handled by Fusion or by the post processor?
Thanks!
