G82 is a drilling cycle similar to G81, but with an added dwell time at the bottom of the hole. After feeding down to the programmed depth (Z), the tool pauses for the specified time (P value) before retracting. This dwell improves hole accuracy, helps create a cleaner bottom surface, and is commonly used for countersinking and counterboring operations.

When programming a Vertical Machining Center (VMC), certain operations like drilling, boring, tapping, and reaming are repetitive. Writing full toolpath codes (G01, G00, G02, G03) for each step would be time-consuming.
To simplify this, Fanuc controls (and most CNC controls) use Canned Cycles – pre-programmed subroutines that perform common machining operations with just one command line.
