7 Programming: Canned Cycles, sub-programs



The tapping canned cycle is used for tapping holes. During a tapping 
cycle, the tool feeds from the R-plane to Z depth.  The spindle stops 
and reverses, the tool feeds to the retract plane, and the spindle 
stops, and then reverses again. 



F (TPIorLead): Enter Threads per Inch when in Inch mode. Enter 
Lead when in MM mode. Lead is the distance from one thread to 
the next. You must program a spindle RPM. The Feedrate is 
calculated based on the spindle RPM and the TPI or Lead specified. 



S (Spindle sync): To enable Spindle sync, enter a value of 1. The 
machine must have direct spindle control to use this feature. The 
spindle rotation and Z-axis movement is synched together, as in a 
threading cycle. 



D (Dwell): A dwell time value in seconds can be entered. You may 
require this feature because of the time required to stop and reverse 
the spindle. 



G-code format: G84

The machine must be equipped with spindle M-functions 
(FWD, REV, OFF) to use this cycle. Do not use the tapping 
cycle if the machine does not have spindle commands 
available.

The Dwell occurs before the top entry to the hole, and 
before the spindle reversal at the bottom of the hole.
