Cycle parameters
Q573 Inscr.circle/circumcircle (0/1)?: Definition
of whether the dimensioning shall reference to the
inscribed circle or to the perimeter:
0= dimensioning refers to the inscribed circle
1= dimensioning refers to the perimeter
Q571 Reference circle diameter?: Definition of
the diameter of the reference circuit. Specify in
parameter Q573 whether the diameter references
to the inscribed circle or the perimeter. Input range:
0 to 99999.9999
Q222 Workpiece blank diameter?: Definition
of the diameter of the workpiece blank. The
workpiece blank diameter must be greater than
the reference circle diameter. The TNC performs
multiple stepovers if the difference between the
workpiece blank diameter and reference circle
diameter is greater than the permitted stepover (tool
radius multiplied by path overlap Q370). The TNC
always calculates a constant stepover. Input range 0
to 99999.9999
Q572 Number of corners?: Enter the number of
corners of the polygon. The TNC will always equally
divide the corners on the stud. Input range 3 to 30
Q224 Angle of rotation?: Specify which angle is
used to machine the first corner of the polygon.
Input range: -360° to +360°
