220 4 Cycle Programming

4.8 Milling Cycles

ICP contour, radial

Call the milling menu.

Select "ICP contour, radial."

Depending on the parameters, the cycle mills a contour or roughs/

finishes a pocket on the lateral surface.

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.
