4-4 Override

Using Overrides

An override is a feature for adjusting the feed rate or spindle speed while cutting is in progress. This is

useful when you want to change the feed rate or speed as you monitor the status of cutting.

An override value is specified as a percentage. For example, when the command in the cutting data

sent from the computer is for a speed of 5,000 rpm, specifying an override of 150% produces an actual

speed of 7,500 rpm.

Cutting Speed Override

This works on the tool movement speed of when the workpiece is being cut. The speed specified by

the command in the cutting data is taken to be 100%.

Spindle Speed Override

This works on the rotation speed of the spindle. The speed specified by the command in the cutting

data is taken to be 100%. This is also effective when rotating the spindle during manual operations.

Important Notes on Overrides

Setting an override does not let you perform operation beyond the machine's maximum or minimum

speeds.
