Cutter Diameter Compensation (CDC) is a key to holding extremely tight tolerances. CNC provides a way for toolpaths to be adjusted to compensate for tool wear and deflection. We get a lot of questions from those new to CNC about how to use compensation. Part of whay makes it so confusing is there are so many options: In Computer, In Control, Wear, Inverse Wear and Off.
