4-4 Override
What's an 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 specied 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 specied 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 specied by the command in the cutting
data is taken to be 100%. This is also eective when rotating the spindle during manual operations.
How to Make the Settings for Overrides
Important Notes on Overrides
Setting an override does not let you perform operation beyond the machine's maximum or minimum
speeds.
