Wire EDM Machine Operation Chapter 10

IMPACT CAD CAM for example is a recommended software that can write the program
using the following machining orders.
Rough cut all openings up to the glue tabs.
Stop the machine
Cut off all TABS, with MOO stops for the operator to remove slugs.
Skim cut all openings without stopping.
Figure 10-3 is a drawing that shows three die openings to be machined in the same piece
of material.
Notice that each start hole has been dimensioned from the lower left-hand corner of the
part. Using techniques you already know, you could use the Q routine 0165 to pick up
that corner. If you pick up the corner of the part while you are in coordinate system
number 4 (G58), you will be able to easily reference that coordinate system at any time
during the program (note that it does not have to be G58, it could be any coordinate
system except G54 or G959.)
Say the left die-opening NC program was named DIE1, the middle die-opening NC
program was named DIE2, and the right die-opening program was named DIE3. Each of
these NC programs could be modified to be a Q routine by deleting the M02’s from the
end of each program, then this ALLDIE program would work:
Program named ALLDIE:
N005 G58 (SELECT COORDINATE SYSTEM FROM LOWER LEFT CORNER)
N006 G92X0Y0
N010 G00 X1. Y2.(RAPID TO FIRST LOCATION)
N015 T91 (AUTOMATIC WIRE THREAD)
N016 G54
N020 QDIE1 (THIS RUNS ENTIRE DIE1 PROGRAM)
N025 T90 (CUT WIRE)
N030 G58 G00 X2.5 Y2.5 (RAPID TO SECOND LOCATION)
N035 T91 (AUTOMATIC WIRE THREAD )
N036 G54
N040 QDIE2 (THIS RUNS ENTIRE DIE2 PROGRAM)
N045 T90 (CUT WIRE)
N050 G58 G00 X4.5 Y1. (RAPID TO THIRD LOCATION)
N055 T91 (AUTOMATIC WIRE THREAD)
N056 G54
N060 QDIE3 (THIS RUNS ENTIRE DIE3 PROGRAM)
USING A COORDINATE SYSTEM TO KEEP TRACK OF THE MACHINE’S POSITION
One VERY helpful technique for Coordinate System Shifting is to keep track of the
