Chapter 4 Tool Nose Radius Compensation(G41,G42)
203
Ⅰ
Programming
1. Execute G40 in a program;
2. Execute
M30.
The system cannot execute G02 and G03 when canceling C tool compensation (tool nose radius
compensation), otherwise the system alarms and stops run.
In compensation canceling mode, the system executes the block and ones in the register
for tool nose radius compensation. At the moment, the run stops after one block is executed
when single block is ON. The system executes the next one but does not read its following one
when pressing
