Programming technology functions (cycles)
10.1 Drilling
Parameter Description
X0 X coordinate of the reference point X (abs)
In the 1st call this position must be programmed absolutely.
Y0
Y coordinate of the reference point Y (abs)
α0
In the 1st call this position must be programmed absolutely.
(only for G Code)
Angle of rotation of the line referred to the X axis
Positive angle: Line is rotated counter-clockwise.
Negative angle: Line is rotated clockwise.
Face C:
Z0 Z coordinate of the reference point (abs)
X0 X coordinate of the reference point – first position (abs)
Y0 Y coordinate of the reference point – first position (abs)
α0 Angle of rotation of line in relation to the X axis
(only for Shop‐
Positive angle: Line is rotated counter-clockwise.
Turn)
Negative angle: Line is rotated clockwise.
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.
X0 X coordinate of the reference point – first position (abs)
Y0 Y coordinate of the reference point – first position (abs)
α0 Angle of rotation of line in relation to the X axis
(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.
