The third key concept to wire EDM programming is that there are four kinds of wire
motion. It should be refreshing for beginners to know that there are only four ways to
cause the machine to move around a shape.
1) G00 - Rapid Motion (without cutting)
2) G01 - Straight Line Motion (with cutting)
3) G02 and G03 - CW Circular Motion and CCW (with cutting)
NOTE: We are using ZERO’S and not the letter O. The center zero can be left out in the
4 examples above.
All movements that the machine makes in order to machine a workpiece can be divided
into one of four types. These commands give you all the power you need to drive the wire
through its programmed path.
All of these commands have two things in common. First, they are all modal, meaning
that once one of these commands is instated, it need not be programmed in subsequent
commands. For example, if you intended to make five straight line motion commands in
a row, you only need to program a G01 in the first of the five commands.
Second, each of these commands require that you program the END POINT of the
motion desired. Remember that you are telling the machine where you want it to move to
in each of these commands. The control will assume that the wire is currently positioned
at the beginning point prior to each of these commands.
Look at the following examples.
