4.11.1 G04: Dwell


Format:

G04 X_

G04 P_


G04：Make program execution dwell X_ or P_ seconds


The G04 dwell instruction is used in the following situations:

  • When the spindle has high-speed and low-speed switching, after the M05 command, dwell with G04 command for a few seconds so that when the spindle is actually stopped, shift the gear again to avoid damaging the spindle's servo motor.
  • Dwell for a few seconds at the bottom of the hole to make the depth of the hole correct and increase the luminosity of the bottom of the hole, such as drill string pit, cone crater, cut fish eye and so on.
  • When tapping a large diameter thread, dwell for a few seconds to stabilize the speed before tapping the thread so that the thread pitch is correct.


Note 1:

In metric systems, the dwell time can be from 0.001 seconds to 9999.999 seconds. In Inch systems, the pause time can be from 0.0001 seconds to 999.9999 seconds.

Note 2:

If X_ or P_ is not given, this command will have the same function as G09.
