(8) Programming for 2-step Hole Machining Canned Cycles*
To execute a hole machining cycle in a hollow workpiece such as a cast workpiece, 2-step
hole machining canned cycles are provided. For each type of canned cycle, called by a G
code of 80s, 2-step hole machining canned cycle is available. To call up a 2-step hole machin-
ing canned cycle, add “100” to a G code number used to call up a hole machining canned
cycle. The following G codes are used to call up the 2-step hole machining canned cycle:
G181, G1 82, G1 85,G186,G187, and G189.
(a) 2-step hole drilling command (G181)
Example of Programming
G181 X_Y_Z_R_L_F_J_K_E_Q_W_;
Note:
To specify J or K in the G91 (incremental) mode, specify the distance in reference to the R-
point level.
