Following cnc programming code shows the use of G72 bolt hole along an angle.
As the names states G70 G-code makes it very easy to drill/bore/tap evenly spaced hole along a specified angle.
Canned cycles G73, G74, G76, G77, or G81-G89 can be used with G72 bolt hole along an angle command.
G72 Bolt Holes Along an Angle Format
G72 I J L
I – Distance between bolt holes along an angle
J – Angle of holes from three o’clock, 0 to 360.0 degrees CCW.
L – Number of evenly spaced holes along an angle
