KIN_TYP_61 – 5-axis kinematics with Y/A workpiece table

Kinematic structure

The kinematic structure consists of one translatory and one rotary NC axis in the workpiece and 2 translatory and one rotary NC axis in the tool.

In the ideal zero position of the kinematic structure, the rotary axis A in the workpiece and the rotary axis B in the tool intersect at one point. The machine axis positions of the tool slide are then 0 in this position. Normally these axis positions cannot be approached with a real machine structure. The offsets at tool slide position 0 to this position can be set with parameters HD7, HD8, HD9.
