3.27.4 Notes on Tool Radius Compensation
1. When radius compensation is executed, there should be at least one block
containing positioning commands between two neighboring blocks. The following
commands do not perform tool positioning, though they have mechanical actions.
Therefore they are not allowed for continuous blocks .
M05 M-code output
S2100 S-code output
G4 X1.000 Suspension
G1 U0.000 Feed distance=0
G98 G-code only
2. Only G00 and G01 are applicable to blocks with tool-tip radius compensation. Arc
commands G02, G03 are not allowed
3. The move block before a tool-tip radius compensation command must be G00 or
G01. Arc commands G02, G03 are not allowed.
4. The tool radius compensation function is not available for MDI operation.
5. Tool-tip radius compensation is not allowed for G74, G75, or G76.
