Wire EDM Machine Operation Chapter 6

U
Used to specify exact movements of the upper wire guide (U axis) left and right (parallel
to X). Used when writing a program that employs independent UV techniques or 4 axis.
U or V 4 axis movements are defined as the incremental value from the X or Y-axis plane
in an absolute mode. For standard taper cutting using G51 and G52, the control will
calculate the required U and V movements without the need for the U and V codes in the
program.
V
The same information applies to V (upper wire guide movement parallel to the Y-axis) as
listed above with the U axis.
I
Used in circular movement commands (G02 and G03). I is defined as the incremental
distance and direction in X from the starting point of a circular move to the center around
which the movement takes place.
J
Used in circular movement commands (G02 and G03). J is defined as the incremental
distance and direction in Y from the starting point of a circular move to the center around
which the movement takes place.
H
Specifies the register in the offset file to be used for wire radius compensation. A value of
.0063 inches would be input as H063 when in 4-digit inch. For 5 digit inch use H630.
A
Used to input the amount of taper angle when using G51 and G52 commands. An angle
of 1.0 degree is input as A1.0
P
Used in the line with M98 to designate the sequence number (line number) of the
beginning of the sub-routine. When the control executes the line M98 P0010 it jumps to
line number N0010 in the subroutine.
L
Can also be used with the sub-routine call to provide multiple executions of the sub-
routine (looping). M98 P0030 L4 would execute the sub-routine 30, four times.
C
Designates the three digit cutting condition number which the control will load from the
condition file or from the header into the generator .The three digits may be any existing
combination from 000 to 999. A Non EF II machine uses 1-199 for the operator to create
their own. An EF II machine uses 1-99.
