KIN_TYP_63 – 5-axis kinematics with X/Y/B workpiece table

Kinematic structure

The kinematic structure consists of 1 translatory and 1 rotary NC axis in the workpiece and 2 translatory and one rotary NC axis in the tool. The transformation supports additional offset parameters for a non-symmetric construction and substitutes the existing kinematic structure KIN_TYP_23.

In the ideal zero position of kinematic structure, the rotary axis B in the workpiece and the rotary axis A 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.
