KIN_TYP_57

The kinematic structure of this machine consists of three translatory axes in tool and two rotary NC axis in workpiece.

Axis designation	X, Y, Z, B, C
Axis index	0, 1, 2, 3, 4
Kinematic structure
	Tool axes	Workpiece axes
NC axes	X, Y, Z	B, C

KIN_TYP_57 4: — Figure 2-51: X, Y offsets to the B axis

The machine origin ca be shifted by the parameters HD7..HD9. Differing zero positions of the rotary axes B and C can be adjusted by the parameters HD10 and HD11 in a way, that the internal kinematic model matches to the real machine kinematic. In the same way also differing rotation directions of the B and C axes can be adjusted by the parameters HD12 and HD13. Then, in general in the axes parameters also the signs of commanded and actual values have to be adjusted correspondingly.
