Input data
l SET-UP CLEARANCE 0200 (incremental value):
Distance between tool tip and workpiece surface. Enter a positive
value.
l DEPTH Q201 (incremental value):
Distance between workpiece surface and bottom of stud. Enter a
negative value.
l FEED RATE FOR PIUNGING 0206:
Traversing speed of the tool when moving to depths in mm/min. If
plunge-cutting into the material, enter a low value; if clearing has
already been carried out, enter a higher feed rate.
l PECKING DEPTH 0202 (incremental value):
lnfeed per cut. Enter a value greater than 0.
l FEED RATE FOR MILLING Q207:
Traversing speed of the tool when milling in mm/min.
l WORKPIECE SURFACE COORDINATE Q203 (absolute value):
Fig. 8.16: Input parameters, STUD FINISH-
Coordinate of the workpiece surface.
ING cycle
l 2ND SET-UP CLEARANCE 0204 (incremental value):
Z coordinate at which no collision between tool and workpiece (clamp-
ing devices) can occur. Enter a positive value.
l CENTER IN 1ST AXIS 0216 (absolute value):
Center of the stud in the main axis of the working plane.
l CENTER IN 2ND AXIS 0217 (absolute value):
Center of the stud in the secondary axis of the working plane.
l FIRST SIDE LENGTH Q218 (incremental value):
Length of the stud, parallel to the main axis of the working plane.
l SECOND SIDE LENGTH Q219 (incremental value):
Length of the stud, parallel to the secondary axis of the working plane.
l CORNER RADIUS Q220:
Radius of the stud corner.
l ALLOWANCE IN 1ST AXIS Q221 (incremental value):
Finishing allowance in the main axis of the working plane, referenced to
the length of the stud. Enter a positive value.
