(2) Adjusting the cutting feed
To adjust the cutting rate, the NC axis specification parameter clamp speed (clamp) and acceleration/deceleration
time constant (G1t*) are adjusted. The in-position width at this time must be set to the same value as actual cutting.
• Determining the clamp rate and adjusting the acceleration/deceleration time constant
(Features)The maximum cutting rate (clamp speed) can be determined freely.
(Adjustment)Carry out cutting feed reciprocation operation with dwell at the maximum cutting rate and adjust the
acceleration/deceleration time constant so that the maximum current command value during
acceleration/deceleration is within the range shown below.
• Setting the step acceleration/deceleration and adjusting the clamp speed
(Features)The acceleration/deceleration time constant is determined with the position loop in the servo, so the
acceleration/deceleration FΔT can be reduced.
(Adjustment)Set 1 (step) for the acceleration/deceleration time constant and carry out cutting feed reciprocation
operation with dwell. Adjust the cutting feed rate so that the maximum current command value during
acceleration/deceleration is within the range shown below, and then set the value in the clamp speed.
