4.8 Milling Cy
cles
ICP contour, axial
Call the milling menu.
Select "ICP contour, axial."
Depending on the parameters, the cycle mills a contour or roughs/
finishes a pocket on the face.
Notes on parameters/functions:
„ Machining of contour or pocket: defined in "U."
„ Milling direction: depends on definition in "H" and the direction of
tool rotation (see “Cutting direction for contour milling and pocket
milling” on page 224).
„ Milling cutter compensation: effective (except for contour milling
with J=0).
„ Approach and departure: For closed contours, the point of the
surface normal from the tool position to the first contour element is
the point of approach and departure. If no surface normal intersects
the tool position, the starting point of the first element (for
rectangles, the longer element) is the point of approach and
departure. The tool approaches directly or on an arc according to
"approaching radius R."
„ Contour milling: "J" 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): "Contour milling J" defines
whether a pocket is machined from the inside towards the outside,
or vice versa.
„ Pocket milling—finishing (O=1): First, the edge of the pocket is
machined; then the pocket floor is machined. "J" defines whether a
pocket floor is finished from the inside towards the outside, or vice
versa.
