9.5 ICP Example "Milling Cycle"
The milling example illustrates the use of an ICP contour for machining
a pattern. The individual working steps for machining the ICP contour
and integrating the contour into ICP cycles are based on the workpiece
drawing.
In the process described below, you create an ICP contour description
and a cycle program for parts production.
The cycle used is "ICP contour, pattern circular, axial."
Required tool
„ Milling tool:
„ Position T40
„ WO = 8 Tool orientation
„ I = 8 Cutter diameter
„ K = 4 Number of teeth
„ TF = 0.025 Feed per tooth
Sequence of working steps
 Preconditions:
– The turning operation is completed.
– The tool dimensions have been determined.
 Switch to "Teach-in" mode.
 Enter the positioning cycles for tool change.
 Call "ICP contour, axial."
 Activate "Pattern, circular" in addition.
 ICP contour programming.
 Integrate the ICP contour in the milling cycle (roughing).
 Generate a milling cycle (finishing).
 Integrate the ICP contour in the milling cycle (finishing).
Note on defining ICP contours in patterns
In this example, the first milling contour is programmed as indicated in
the workpiece drawing. The coordinate datum therefore is the
reference point for the definition of the pattern positions.
Alternately, you can dimension the first milling contour "in the
coordinate datum" and define the position of the milling contours in the
pattern positions.
