Input data
l
SET-UP CLEARANCE Q200 (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 PLUNGING Q206:
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 Q202 (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):
Coordinate of the workpiece surface.
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 Q216 (absolute value):
Center of the stud in the main axis of the working plane.
l
CENTER IN 2ND AXIS Q217 (absolute value):
Center of the stud in the secondary axis of the working plane.
l
WORKPIECE BLANK DIAMETER Q222:
Diameter of the premachined stud. Enter the workpiece blank diameter
to be greater than the diameter of the finished part.
l
FINISHED PART DIAMETER Q223:
Diameter of the finished stud. Enter the diameter of the finished part to
be less than the workpiece blank diameter.
