10.1 Drilling
Parameter Description
Face Y:
Z0 Z coordinate of the reference point (abs)
CP Positioning angle for machining area
The CP angle does not have any effect on the machining position in relation to the work‐
piece. It is only used to position the workpiece with the rotary axis C in such a way that
machining is possible on the machine.
X coordinate of the reference point – first position (abs)
X0
Y coordinate of the reference point – first position (abs)
Y0
Angle of rotation of line in relation to the X axis
α0
(only for Shop‐ Positive angle: Line is rotated counter-clockwise.
Turn)
Negative angle: Line is rotated clockwise.
Peripheral surface C:
X0 Cylinder diameter ∅ (abs)
Y0 Y coordinate of the reference point – first position (abs)
Z0 Z coordinate of the reference point – first position (abs)
α0 Angle of rotation of line with reference to Y axis
(only for Shop‐
Positive angle: Line is rotated counter-clockwise.
Turn)
Negative angle: Line is rotated clockwise.
Peripheral surface Y:
X0 X coordinate of the reference point (abs)
C0 Positioning angle for machining surface
Y0 Y coordinate of the reference point – first position (abs)
Z0 Z coordinate of the reference point – first position (abs)
α0 Angle of rotation of line with reference to Y axis
(only for Shop‐
Positive angle: Line is rotated counter-clockwise.
Turn)
