Retraction plane (absolute)
Reference plane (absolute)
Safety distance (to be added to the reference plane, enter without sign)
Depth (absolute)
Starting point, abscissa (absolute)
Starting point, ordinate (absolute)
Rectangle length along the 1st axis, incremental.
The corner from which dimensions are measured is given by the plus/minus
sign.
Rectangle length along the 2nd axis, incremental.
The corner from which dimensions are measured is given by the plus/minus
sign.
Angle between the longitudinal axis of the rectangle and the first axis of the
plane (abscissa, enter without sign);
Value range: 0° ≤ _STA < 180°
Maximum infeed depth (enter without sign)
Maximum infeed width value for solid machining in the plane (enter without sign)
Retraction travel in cutting direction (incremental, enter without sign)
Final machining allowance in depth (incremental, enter without sign) In the
roughing mode, _FALD refers to the remaining material on the surface.
Feedrate for surface machining
Type of machining: (enter without sign)
UNITS DIGIT:
Value: 1...Roughing
2...Finishing
TENS DIGIT:
Value: 1...Parallel to the abscissa, in one direction
