1. G Function Description
Description:
1. use G00 to positioning to specified (X,Y) when start to perform
2. after OSS stops ,use the direction that parameter 4020 specify ,and
shift amount a Q distance in reverse direction
3. use G00 to reach specified point R, shift amount a Q distance,
4. drill rotate CW.
5. G01 command to raise to point Z
6. after dwell P(s) and shift amount a Q distance in reverse direction
7. G00 command to raise to initial point
8. after drill start and shift amount a Q distance.
※Alarm:
Q is a Modal Value that request in G87 cycle. This Q value must
be specified carefully because it is also used in G73/G83 cycle.
OSS(Oriented Spindle Stop) direction is decided by parameter No.

Notes:
1. before G87 command, use M Code to let the spindle rotate.
2. if M Code and G87 are specified in the same block , this M Code
only executes in the first time of positioning in that block
3. when K is used to specify numbers of times, this M Code is
executed for the first only, for the second hole and subsequent
holes, the M Code is not executed.
Condition:
1. before drilling axis changes, Canned Cycle must be canceled first.
2. if the Block does not include movement command of any axes (X,
Y, Z), then drilling will not be executed.
