5. Ensure safe rapid approach motion. The most dangerous time for a CNC user is when a cutting tool approaches for the first time. It will be moving at the machine's rapid rate to a position that is very close to the work surface. Most programmers use a rapid approach distance of in (about mm) — some even closer.
