Function
The control is always looking ahead to the next motion block to determine
the actual tool path taken for a motion block in compensation. If the next
program block is not a motion block, the control continues to scan ahead
for a motion block until it either detects one or until the allowable number
of non-motion blocks as set with this parameter is reached.
Axis Parameter

All [29]
Range
0 to 25 blocks
Notes
This is a global parameter. The value set here applies to all axes
and processes.
The Automatic Corner Override feature compensates for increased spindle
loading when cutting inside corners with cutter compensation active.
Since the relative speed between the part and the cutting tool edge
increases when cutting inside corners, a more uniform finish and reduced
tool loading results if the feedrate is reduced.
The feedrate is reduced to the percentage entered for the AMP parameter
Corner Override %, when these conditions are met:
Cutter Compensation (G41/G42) is active
Automatic Corner Override (G62) is active
the corner angle (or angle between arc tangent lines) is equal to or
greater than the value entered for the AMP parameter Corner
Override Angle
the tool has reached the point defined by the AMP parameter Corner
Override Distance (DTC)
the tool has not reached the point defined by the AMP parameter
Corner Override Distance (DFC)
