31.3.3 Description of Operation

31.3.3.1 Adjustment by Setting Value of Scale Model Gain (PGM)
OMR-CC can perform more accurate machining by increasing the setting value of "#2306 SV106 PGM".
When the tool path bulges outside the program path where the curvature of the program path decreases (*1), set a larger
parameter setting value. The path error is reduced and the bulge of the tool path is eliminated (*2).
To shorten the cycle time, set a larger parameter setting value.
When mechanical vibration occurs, the vibration can be reduced by setting a smaller parameter setting value.
(*1) When the tool path bulges outside the program path where the curvature of the program path decreases
(*2) When the scale model gain is large enough and the path error is small

31.3.3.2 Adjustment by OMR-CC Compensation Factor

OMR-CC can adjust the feedrate in the curved part by changing "#2679 OMRCC_CompMag".
To shorten the cycle time, set a larger parameter setting value.
The degree of reduction in cycle time also depends on the machining program. In a machining program with few smooth
curves, the cycle time may not be shortened even though a larger parameter setting value is set.
When mechanical vibration occurs, the vibration can be reduced by setting a smaller parameter setting value.
When the compensation magnification is the minimum ("#2679 OMRCC_CompMag" is set to "1"), the cycle time is
approximately the same as when the OMR-FF control is being performed.

31.3.3.3 Difference Between OMR-CC and OMR-FF

Compared to OMR-FF, which has the same setting value as "#2306 SV106PGM", OMR-CC can shorten the machining time
while maintaining machining accuracy.
