Procedure
Parameters Description
LAB Repeat jump label for position
(only for G code)
PL Machining plane
(only for G code)

ShopTurn)
Please note that when machining in the face C and peripheral surface C planes,
clamping only remains active for the drilling operation. On the other hand, when
machining in the face Y and peripheral surface Y planes, clamping is modal, i.e. it
remains active until the machining plane is changed.
Position pattern Selection option for the following patterns:
Line

Matrix

Box

X0 X coordinate of the reference point X (abs)
This position must be programmed absolutely in the 1st call.
Y0 Y coordinate of the reference point Y (abs)
This position must be programmed absolutely in the 1st call.
α0 Angle of rotation of the line referred to the X axis
(only for G-Code) Positive angle: Line is rotated counterclockwise.
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
Positive angle: Line is rotated counterclockwise.
ShopTurn)
Negative angle: Line is rotated clockwise.
