204 4 Cycle Programming

4.8 Milling Cycles

Figure, axial

Call the milling menu.

Select the "Figure, axial" cycle.

Depending on the parameters, the cycle mills one of the following

contours or roughs/finishes a pocket on the face:

 Rectangle (Q=4, L<>B)

 Square (Q=4, L=B)

 Circle (Q=0, RE>0, L and B: No input)

 Triangle or polygon (Q=3 or Q>4, L>0)

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: 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.
