N_ G41
The G41 command applies cutter compensation to the left hand side of the programmed tool path. This amount is equal to the current tool's nose radius value, which is stored in the Tool Offset Register table of the controller. This register number is referenced by the last two digits in the tool change command. For example, a tool change command with T0202 will reference the tool nose radius value in register #2.
