20. HIGH SPEED CUTTING FUNCTIONS
441
This function is designed for high–speed precise machining. With this
function, the delay due to acceleration/deceleration and the delay in the
servo system which increase as the feedrate becomes higher can be
suppressed.
The tool can then follow specified values accurately and errors in the
machining profile can be reduced.
This function becomes effective when look–ahead control mode is
entered.
For details, refer to the relevant manual published by the machine tool
builder.
