Boring Bidirectional Cycle

Boring Bidirectional is a boring cycle, generally used to make a pass in each direction on a bore or to tap with a self-reversing tapping head. It feeds from the R-plane to Z depth, and then feeds back to the retract height.

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.
Feed	F	Feedrate
Dwell	D	Dwell time

G-code format: G85

Boring Unidirectional Cycle

Boring Unidirectional is a boring cycle that allows the X-axis to back off the bore surface after the spindle has stopped and oriented itself. The cycle feeds from the R-plane to Z depth, dwell for the specified time, stop and orient the spindle to the specified angle C, back off in X, rapid retract in Z, re-position in X, and restart the spindle.

Your machine must be equipped with spindle M-functions (Spindle Forward [M3], Spindle Reverse [M4], Spindle Off [M5]) and spindle orientation (M19) to use this cycle. Do not use this cycle if the machine does not have the spindle commands and spindle orientation.

Field	Code	Description
ZDepth	Z	Absolute hole depth. (Required)
StartHgt	R	Initial Z start point, in rapid. (Required)
X Backoff	I	X-axis incremental backoff distance in X
		(positive or negative dimension).
Feed	F	Feedrate
ReturnHgt	P	Z retract height after hole depth, in rapid.
Index	C	M19 index angle. If no angle is given, the
Angle		angle for spindle orientation defaults to
		zero.
Dwell	D	Dwell time (in seconds).
