Tool wear compensation in CNC turning is the process of adjusting the tool offset values in the CNC control to account for the gradual wear of the cutting tool. This compensation is necessary to maintain dimensional accuracy as the tool wears down during machining. The first step is to establish a baseline. Machine a test part with a new or sharp tool and measure its dimensions. This provides a reference point for determining the amount of wear. Next, monitor tool wear. As the tool is used, periodically measure the dimensions of machined parts. The difference between the measured dimensions and the....
