Acu-Rite CNC 3500i user manual Counterbore Drill Cycle, Peck Drill Cycle, 149

Counterbore Drill Cycle

Counterbore drill cycle generally used for counterboring. It feeds from the R-plane to Z depth, dwells for specified time, then rapids to the return point.

Field	Code	Description
ZDepth	Z	Absolute hole depth. (Required)
StartHgt	R	Initial Z start point, in rapid. (Required)
ReturnHgt	P	Z return point after hole depth, in rapid.
Dwell	D	Dwell time (in seconds). (Required)
Feedrate	F	Feedrate

G-code format: G82

Peck Drill Cycle

The peck drilling cycle is generally used for peck drilling relatively shallow holes. It feeds from the R-plane to the first peck depth (calculated so that all pecks are equal and do not exceed the maximum peck distance programmed in I word). Then rapid retracts to R-plane (to clear chip), rapids down to previous depth less .02", and continues this loop until it reaches the final hole depth. It then rapid retracts to the P dimension.

Field	Code	Description
ZDepth	Z	Absolute hole depth. (Required)
StartHgt	R	Initial Z start point, in rapid. (Required)
ReturnHgt	P	Z return point after hole depth, in rapid.
Peck	I	Maximum peck distance (positive
		dimension). (Required)
Feedrate	F	Feedrate
