If the event is a:
•
DRILL
, then an incremental move is from the X, Y programmed in that previous event.
•
BOLT HOLE
, then an incremental move is from the X CENTER, Y CENTER
programmed in that event.
•
MILL
, then an incremental move is from the X END, Y END programmed in that
event.
•
ARC
, then an incremental move is from the X END, Y END programmed in that
event.
•
CIRCLE POCKET
or
FRAME
, then an incremental move is from the X CENTER, Y
CENTER programmed in that event.
•
RECTANGLE POCKET
or
FRAME
, then an incremental move is from the first or X1,
Y1 corner programmed in that event.
•
REPEAT
, then an incremental move is the same as for the event types shown
above, but shifted by the programmed OFFSET.
•
Z rapid and Z Depth
are always incremental from the previous event. Applicable
to the DPMEX2 product.
5.3 Referenced and Non-Referenced Data
Data is always loaded into the ProtoTRAK EMX by using the INC SET or ABS SET key.
X, Y, Z positions are referenced data. In entering any X, Y, or Z position data, you must
note whether it is an incremental or absolute dimension and enter it accordingly. All other information
(non-referenced data), such as tool diameter, feedrate, etc. is not a position
and may, therefore, be loaded with either the INC SET or ABS SET key. This manual
uses the term SET when either INC SET or ABS SET may be used interchangeably.
5.4 Tool Diameter Compensation
Tool diameter compensation allows the
machined edges shown directly on the
workpiece to be programmed instead of the center of
the tool. The ProtoTRAK EMX then
automatically compensates for the
programmed geometry so that the desired
results are obtained.
If the cutter in the sketch above is moving from left to right from point X1, Y1 to X2, Y2 and on to X3,
Y3, these actual points can be programmed instead of the center of the cutter.
Or, the actual desired circle with radius R can be programmed instead
of the radius of the center of the cutter Rc.
