To make clean efficient cuts on a CNC Router, picking the proper feed rates and spindle RPM is crucial. But many are not sure how this is accomplished and end up using settings that lead to poor cuts and premature wear on their tools. The CNC EXPLORER is a tool to help understand various settings on a CNC Router. Interactive adjustments encourage the exploration of different settings and trade-offs. The tool monitors settings that would create over-stresses on the CNC system. The result is a set up within the capabilities of the machine tooling producing a good efficient and safe cut.
