TRAK LPM Programming, Safety, & Operating Manual
# of Variable Pecks: the factory setting is for each peck to be successively smaller,
taking the largest cuts at the beginning and the smallest at the end. When the highlight is
on this prompt, you may change this setting by pressing the HELP key. This will take
you to a screen where you may choose to have a fixed amount of material taken per peck
or have the cutter move up just enough to break the chip before continuing to feed down.
RPM: is the spindle RPM for the event. INC SET will use the RPM of the previous
event.
Z Feedrate: is the drilling feedrate
Tool #: is the tool number you assign
8.4 MILL Events
This event allows you to mill in a straight line from any one XYZ point to another,
including at a diagonal in space. It may be programmed with a CONRAD if it is
connective with the next event (this next event must lie in the same plane as the Mill
event).
Prompts for the Mill Event:
X Begin: is the X dimension to the beginning of the mill cut
Y Begin: is the Y dimension to the beginning of the mill cut
Z Rapid: is the Z dimension to transition from rapid to feed
Z Begin: is the Z dimension to the beginning of the mill cut
X End: is the X dimension to the end of the mill cut; incremental is from X Begin
Y End: is the Y dimension to the end of the mill cut; incremental is from Y Begin
Z End: is the Z dimension to the end of the mill cut; incremental is from Z Begin.
Conrad: is the dimension of a tangential radius to the next event (that must lie in the
same plane for part geometry programming)
Tool Offset: is the selection of the tool offset to right (input 1), offset to left (input 2), or
tool center--no offset (input 0) relative to the programmed edge and direction of tool
cutter movement and as projected in the XY plane.
RPM: is the spindle RPM for the event. INC SET will use the RPM of the previous
event.
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: is the milling feedrate from Begin to End in in/min from .1 to 800, or
mm/min from 5 to 20320
Tool #: is the tool number you assign
Note: to program a series of connected lines and arcs on the same plane, use the Pocket or
Profile events.
8.5 ARC Events
This event allows you to mill with circular contouring any arc (fraction of a circle) that
lies in the XY plane or a vertical plane (see Section 5.3). Vertical plane arcs are also
limited to those that are entirely concave or convex (in other words, if you think of the
arc lying on the surface of the earth, then it can't cross the equator, again limited to
quadrants surface of the earth , going from the equator to the South Pole).
