Cycle parameters
U
First side length Q218: Stud length, parallel to the
reference axis of the working plane. Input range 0 to
99999.9999
U
Workpiece blank side length 1 Q424: Length of the
stud blank, parallel to the reference axis of the
working plane. Enter Workpiece blank side length 1
greater than First side length. The TNC performs
multiple stepovers if the difference between blank
dimension 1 and finished dimension 1 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
U
Second side length Q219: Stud length, parallel to
the minor axis of the working plane. Enter
Workpiece blank side length 2 greater than
Second side length. The TNC performs multiple
stepovers if the difference between blank dimension
2 and finished dimension 2 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
U
Workpiece blank side length 2 Q425: Length of the
stud blank, parallel to the minor axis of the working
plane. Input range 0 to 99999.9999
U
Corner radius Q220: Radius of the stud corner. Input
range 0 to 99999.9999
U
Finishing allowance for side Q368 (incremental):
Finishing allowance in the working plane, is left over
after machining. Input range 0 to 99999.9999
U
Angle of rotation Q224 (absolute): Angle by which
the entire stud is rotated. The center of rotation is the
position at which the tool is located when the cycle is
called. Input range –360.000 to 360.000
U
Stud position Q367: Position of the stud in reference
to the position of the tool when the cycle is called:
0: Tool position = Center of stud
1: Tool position = Lower left corner
2: Tool position = Lower right corner
3: Tool position = Upper right corner
4: Tool position = Upper left corner
