3D face milling
The tool parameters relevant to the tool description in 3D face milling are dependent on the tool
type used. Thus, for example, for a ball end mill, only tool parameter 6, for a bevel cutter with
corner rounding additionally tool parameters 7, 9 and 11, are relevant.

Further information
Please refer to the following documentation for information about entering tool shapes in tool
parameters 6 to 11 and how these are calculated by geometry tool radius compensation in the
three geometry axes:
● Programming Manual NC programming; Section "Fundamentals" > "Tool offsets" > "2½ D
tool offset"
● W5: 3D tool radius compensation (Page 237)
