PROGRAMMING16. HIGH SPEED CUTTING FUNCTIONS
The AI contour control/AI nano contour control function is provided for
high–speed, high–precision machining. This function enables
suppression of acceleration/deceleration delays and servo delays that
become larger with increases in the feedrate and reduction of machining
Look–ahead acceleration/deceleration before interpolation is enabled for
up to 40 blocks in AI contour control or for up to 180 blocks in AI nano
contour control. This enables execution of smooth acceleration/
deceleration extending over multiple blocks and higher machining.
The AI nano contour control function calculates a position command to
be output to the digital servo in nanometers (nm) with nano–interpolation,
so the machine can be moved smoothly and the surface precision is
This function is enabled by setting the AI contour control or AI nano
contour control mode.
G05.1 Q _ ;
Q1 : AI contour control/AI nano contour control mode on
Q0 : AI contour control/AI nano contour control mode off
1 Always specify G05.1 in an independent block.
2 The AI contour control/AI nano contour control mode is also
canceled by a reset.
3 When the AI nano contour control option is installed, bit 0
(NAN) of parameter No. 7053 is set to 1 to set the AI contour
