If you are doing all the machining for the pocket at once, i.e. centering, rough-drilling and
removing stock directly in sequence, and do not set the additional parameters for
centering/rough-drilling, the cycle will take these parameter values from the stock removal
(roughing) machining step. When programming in G code, these values must be specifically
re-entered.
