What is Wire EDM ?
If you wish to know more about the Wire EDM process, I invite you to watch this seven minutes video clip I have found on YouTube:
Introduction to CNC ISO Programming
Most Wire EDM machines are controlled by ISO 6983 programs.
An ISO program is usually contained in an ASCII text file that can be transferred to the memory of a CNC machine using a serial cable, but it can also be punched on a paper ribbon for older CNC machines.
It contains instructions that the numerically controlled machine can execute.

The following is a program that cuts a 2" square with the wire offset to the right and a 5˚ taper angle:

Note : 25400 = 25.4 mm = 1" and A5000 is a 5˚ angle.
