Simplify G04 Dwell Time Calculation: A Practical, Cost‑Effective Method
G04 Dwell Time
Some CNC controls has just one option for G04 dwell time the number of seconds the machine will wait, but now you have a rather easy and a bit economical way.
Suppose you are using a reamer or flat drill for boring plus bore-face finish, previously we just guess how much time will it take to finish the face in the bottom, it might be 2 or 3 seconds.
But now just easy give the number of revolution and the G04 dwell will finish when the specified number of revolutions are complete. For a machinist it is the easier way because now he handles it the machine way not like a stop watch.
The code below says that the machine will wait for the next three seconds.
