What procedure would you follow to change a tool bit on a CNC machine?

Shutting down the machine before changing a tool bit ensures safety for the operator and the equipment. When working with CNC machines, it is crucial to prevent any accidents that may occur if a tool is changed while the machine is still powered on and operational.

The process involves safely removing the old tool, which may have sharp edges or may be hot from use, thereby minimizing the risk of injury. After removing the tool, installing the new one requires secure fitting to ensure accurate machining. Resetting the parameters is also essential, as it guarantees that the CNC program accurately reflects the new tool specifications, including offsets and cutting speeds, leading to optimal performance.

This procedure emphasizes both safety and precision, which are critical in CNC machining operations.
