Cutter compensation or sometimes referred to as "cutter comp", is an offset or shift from center line of the tools shaft to the cutters edge along a programmed path. The advantage of cutter compensation is the use of geometry based offsets rather than tool center point, allowing for the same program to use different diameter tools... What is Cutter Compensation? Cutter compensation (cutter comp), also sometimes called Cutter Diameter Compensation (CDC), provides a way to adjust the toolpath at the machine to compensate for tool size, tool wear, and tool deflection. When I originally started programming by manually writing G-Code, I used cutter comp to offset the tool by the.

What are the different methods to do the cutter compensation and what g-codes are used? Types of Cutter Compensation - Tool Length & Cutter Radius Compensation. After using the cutter compensation function, you only need to change the tool position compensation value without modifying the CNC program. Below let's take a look at two different.. When we use cutter compensation, the machine automatically compensate to the radius of our tool so that we are cutting to the size of the part. For cutter compensation to work, the machine needs to know the diameter of our tool. So if we are using a 1/2″ diameter tool, we would offset it by 1/4″. G41 and G42 are the two codes that we need.
