the canned cycle for clearance to the next XY location. Changes to the G98/
G99 selection can also be made after the canned cycle is commanded, which
will affect all later canned cycles.
A P address is an optional command for the some of the canned cycles. This is
a programmed pause at the bottom hole to help break chips, provide a smooth-
er finish and relieve any tool pressure to hold closer tolerance. Note that if
a value for P is entered for one canned cycle it will be used in others unless
cancelled (G00, G01, G80 or the Reset button).
An S (spindle speed) command must be defined in, or before the G-code line
of code.
Tapping in a canned cycle needs a feed rate calculated. The Feed Formula is:
Spindle speed divided by Threads per inch of the tap = Feedrate in inches per
minute
Canned Cycles also benefit from the use of Setting 57. Turning this setting ON
will perform an exact stop between rapids. This is useful to avoid nicking the
part at the bottom of the hole.
Note: The Z, R, and F addresses are required data for all canned cycles.
Canceling a Canned Cycle
The G80 code is used to cancel all canned cycles; note that a G00 or G01
code will also cancel a canned cycle. Once selected, a canned cycle is active
until canceled with G80, G00 or G01.
