 CONCISE GUIDE FANUC 22 
The linear movement programmed with G1 can be linked to the movement of the next block by a chamfer  
(,C) or a connecting radius (R). 
For two-axis machines (without the axis C option) the chamfer can be identified by just the letter C 
followed by the value (and not by ,C) 
Example: 
These functions can only be programmed in a “G1” block. It is also important to underline that the block 
following one containing “R” or “,C” must be a G1 work movement so that the chamfer or radius can be 
calculated by the control.
