PITCH - the distance from one thread to the next in inches or mm. It is equal to one
divided by the number of threads per inch. For example, the pitch for a 1/4-20 screw is 1
20 = .05 inches
RPM: spindle RPM
Tool #: is the tool number you assign
8.12 THREAD MILL Event
To program a Thread Mill Event press the THREAD MILL soft key. This event includes
an automatic move in and out by 0.050” of the thread. Prompts in the Thread Mill Event:
X CENTER: the X dimension of the center of the thread
Y CENTER: the Y dimension of the center of the thread
Z RAPID: the Z dimension where the Z rapid feed slows to Z program feed
Z BEGIN: the Z dimension where the threading pass begins
Z END: the Z bottom of the thread
DIRECTION: clockwise or counterclockwise
PITCH: the distance from one thread to the next in inches or mm. It is equal to one
divided by the number of threads per inch. For example, the pitch for a 1/4-20 screw is
1/20 = .05 inches
MAJOR DIA: the largest diameter of the thread (the root for an ID thread, the crest for an
OD thread)
MINOR DIA: the smallest diameter of the thread (the root for an OD thread, the crest for
an ID thread)
SIDE: input 1 for inside, 2 for outside
ANGLE: the angle the tool feeds into the beginning depth
# PASSES: - the number of passes to cut the thread to its final depth
FIN CUT: width of the finish cut. If 0 is input, there is no finish cut.
Z FEEDRATE: is the Z feedrate from Z rapid to Z end in in/min from .1 to 700, or
mm/min from 5 to 17780
XYZ FEEDRATE: The feedrate of XYZ along the path of the helix.
If something other than 0 is input for finish cut, the following prompt appears:
FIN FEEDRATE: the milling feedrate for the finish cut.
RPM: is the spindle RPM for the event. INC SET will use the RPM of the previous
event.
FIN RPM: is the spindle RPM for the finish cut.
TOOL#: is the tool number you assign.
8.13 PAUSE Events
The purpose of the Pause Event is to allow you to program a stop condition within the
program. The Pause event will stop the program where it ended at the previous event. If
you open the door during a Pause Event the spindle and coolant will turn off
