Notes on parameters and functions:
Machining of contour or pocket: Defined with
Overlap factor U
Milling direction: Depends on definition of
Mill
cutting direction H and the direction of tool rotation
Further information:
"Milling direction for contour
milling", Page 388
Milling cutter radius compensation:
Effective
(except for contour milling with
J
=0)
Approach and departure: For closed contours, the
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): Use
JT
to define
whether a pocket is machined from the inside toward
the outside, or vice versa
Pocket milling—finishing (
O
=1):
First, the edge
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
