KIN_TYP_81 – 5-axis kinematics with B/A workpiece table

Kinematic structure

The kinematic structure consists of 3 translatory NC axes in the tool and 2 rotary NC axes in the workpiece.

In the ideal zero position of the kinematic structure, the rotary axis B in the workpiece and the reference point on the tool slide (here tool holding device) intersect at one point. The machine axis positions of the tool slide are then 0 in this position. In general these axis positions cannot be approached with a machine. The offsets to this position at tool slide position 0 can be set with parameters HD10, HD11, HD12.
