Teach-in | Milling cycles
RB: Return plane
SCI: Safety clearance in the working plane
SCK: Safety clearance in infeed direction
Further information:
Page 180
MT: M after T: M function that is executed after the tool call T
MFS: M at beginning: M function that is executed at the
beginning of the machining step
MFE: M at end: M function that is executed at the end of the
machining step
WP: No. of spindle – Displays which workpiece spindle is used
to execute the cycle (machine-dependent)
Main drive
Opposing spindle for rear-face machining
BW: Angle in the B axis (machine-dependent)
CW: Reverse the tool (machine-dependent)
HC: Shoe brake (machine-dependent)
DF: Miscellaneous function (machine-dependent)
Type of machining for technology database access:
Milling
Notes on parameters and functions:
Machining of contour or pocket:
Overlap factor U
Milling direction:
cutting direction H and the direction of tool rotation
Further information:
milling", Page 388
Milling cutter radius compensation:
(except for contour milling with J=0)
Approach and departure:
starting point of the first element (in rectangles,
the longer element) is the point of approach and
departure. The tool approaches directly or on an arc
according to Approach radius R
Contour milling JK defines whether the milling
cutter is to machine on the contour (center of milling
cutter on the contour) or on the inside/outside of the
contour
Pocket milling—roughing (O=0):
whether a pocket is machined from the inside toward
the outside, or vice versa
Pocket milling—finishing (O=1):
of the pocket is machined; then the pocket floor is
machined. With JT you define whether a pocket floor
is to be finished from the inside towards the outside,
or vice versa
