The high-speed peck drilling cycle performs intermittent feeding along the Z-axis. When this
cycle is used,chips can be removed from the hole easily,and a smaller value can be set for retraction.
This allows drilling to be performed effectively.
P1 in User parameter sets the value of clearance(d).
The tool is retracted in rapid traverse.
Before specifying G73, rotate the spindle using a miscellaneous function (M code).When the
G73 code and an M code are specified in the same block, the M code is executed at the time of the
first positioning operation. The system then proceeds to the next drilling operation.
When a tool length offset(G43 G44 or G49) is specified in the canned cycle, the offset is
applied at the time of positioning to point R.
Note: 1. In a block that doesn't contain R,Q , drilling isn't performed.Specify R and Q in blocs that perform
drilling. If they are specified in a block that doesn't perform drilling, they cannot be stored as modal data.
2. Do not specify a G code of the 01 group(G00-G03) and G73 in a single block.Otherwise, G73 will be
canceled.
3. In the canned cycle mode, tool offsets are ignored.
4. Before the drilling axis can be changed, the canned cycle must be canceled.
