Cycle parameters
 Machining operation (0/1/2) Q215: Define the
machining operation:
0: Roughing and finishing
1: Only roughing
2: Only finishing
Side finishing and floor finishing are only executed if
the finishing allowance (Q368) has been defined
 1st side length Q218: Stud length, parallel to the
reference axis of the working plane. Input range 0 to
99999.9999
 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 1st 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
 2nd side length Q219: Stud length, parallel to the
minor axis of the working plane. Enter Workpiece
blank side length 2 greater than 2nd 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
 Depth Q201 (incremental): Distance between
workpiece surface and bottom of stud. Input range
-99999.9999 to 99999.9999
 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
 Plunging depth Q202 (incremental): Infeed per cut.
Enter a value greater than 0. Input range 0 to
99999.9999
 Feed rate for milling Q207: Traversing speed of the
tool during milling in mm/min. Input range 0 to
99999.999; alternatively FAUTO, FU, FZ
 Feed rate for plunging Q206: Traversing speed of
the tool while moving to depth in mm/min. Input
range 0 to 99999.999; alternatively FMAX, FAUTO,
FU, FZ
