What is the role of a tool path in CNC machining?

In CNC machining, the tool path plays a critical role as it defines the designated route that the cutting tool follows during the machining process. This path is programmed based on the desired shape and dimensions of the workpiece, ensuring precise and accurate material removal as the machine executes the necessary operations. A well-defined tool path is essential for achieving the required tolerances and surface finishes.

The tool path also directly influences factors like machining time and efficiency, as it can determine how quickly the cutting tool can move to remove material effectively without unnecessary movements. Furthermore, a correctly planned tool path helps prevent collisions or tooling errors that might occur during machining, enhancing safety and operational reliability in a CNC environment.
