1 3 3 G Codes 96-8000 rev R June 2007
G70 Bolt Hole Circle (Group 00)
I Radius (
+CCW / -CW
)
J Starting angle (0 to 360.0 degrees CCW from horizontal; or
3 o’clock position
)
L Number of holes evenly spaced around the circle
This non-modal G code must be used with one of the canned cycles G73, G74, G76, G77, or G81-G89. A canned
cycle must be active so that at each position, a drill or tap function is performed.
G71 Bolt Hole Arc (Group 00)
I Radius (
+CCW / -CW
)
J Starting angle (degrees CCW from horizontal)
K Angular spacing of holes (
+ or –
)
L Number of holes
This non-modal G code is similar to G70 except that it is not limited to a complete circle. G71 belongs to Group 00
and thus is non-modal. A canned cycle must be active so that at each position, a drill or tap function is performed.
G72 Bolt Holes Along an Angle (Group 00)
I Distance between holes (
+CCW / -CW
)
J Angle of line (degrees CCW from horizontal)
L Number of holes
This non-modal G code drills “L” number of holes in a straight line at the specified angle. It operates similarly to
G70. For a G72 to work correctly, a canned cycle must be active so that at each position, a drill or tap function is
performed.

Rules For Bolt Pattern Canned Cycles:
1. The tool must be placed at the center of the bolt pattern before the canned cycle execution. The center is
usually X0, Y0.
2. The J code is the angular starting position and is always 0 to 360 degrees counterclockwise from the three
o’clock position.
Looping Canned Cycles
The following is an example of a program using a drilling canned cycle that is incrementally looped.
NOTE: The sequence of drilling used here is designed to save time and to follow the
shortest path from hole to hole.
