E - Specifies the distance from the start position to the bottom of the hole
F - Feedrate
I - Optional size of first cutting depth
J - Optional amount to reduce cutting depth each pass
K - Optional minimum depth of cut
P - Optional pause at end of last peck, in seconds
Q - The cut-in value, always incremental
A - A-Axis tool starting position
B - B-Axis tool starting position
X - X-Axis tool starting position
Y - Y-Axis tool starting position
Z - Z-Axis tool starting position

A specific X, Y, Z, A, B position must be programmed before the canned cycle is commanded.

If I, J, and K are specified the first pass will cut in by amount I, each succeeding cut will be reduced by amount J, and the minimum cutting depth is K.

A P value is used the tool will pause at the bottom of the hole after the last peck for that amount of time. The following example will peck several times and dwell for one and a half seconds at the end:

G163 E0.62 F15. Q0.175 P1.5.
note: The same dwell time applies to all subsequent blocks that do not specify a dwell time.

G163 5-Axis Normal Peck Drilling Canned Cycle: [#22] Setting 22, [#52] Setting 52.

Setting 52 also changes the way G163 works when it returns to the start position. Usually the R plane is set well above the cut to ensure that the peck motion allows the chips to get out of the hole. This wastes time as the drill starts by drilling empty space. If Setting 52 is set to the distance required to clear chips, the start position can be put much closer to the part being drilled. When the chip-clearing move to the start position occurs, the Z axis moves above the start position by the amount given in this setting.
