What is wire EDM technology?
Wire EDM machining (Electrical Discharge Machining) is an electro thermal production process where a thin single strand metal wire, along with de-ionised water (used to conduct electricity) allows the wire to cut through metal by the use of heat from electrical sparks, while preventing rust.
What does EDM stand for in manufacturing?
Electrical discharge machining
Electrical discharge machining (EDM) is a non-traditional machining process based on removing material from a part by means of a series of repeated electrical discharges between tools, called electrodes, and the part being machined in the presence of a dielectric fluid. From: Machining and machine-tools, 2013.
What are the types of EDM machines?
Types of EDM. Electric discharge machining can be divided into three common types, Die sinking EDM, Wire EDM and hole drilling EDM.
What is EDM programming?
A wire EDM machine is programmed like all computer numerical control machines, with a CAM software. Software such as Mastercam converts a programmer’s instructions into the code that controls a wire EDM machine to cut parts to exact specifications.
Is wire EDM a CNC?
Tight Tolerances Wire EDM uses CNC technology to control the wire’s path with unmatched precision—making it an ideal solution for the production of parts with precise dimensions and extremely high tolerances.
Is EDM the same as CNC?
EDM is a manufacturing and prototyping process for metal parts. An EDM machine is similar in construction to a CNC machine, with the important distinction that EDM uses electrical discharges (sparks) to cut through the metal material instead of a sharp cutting tool.
What are EDM applications?
The EDM process is most widely used by the mold-making, tool, and die industries, but is becoming a common method of making prototype and production parts, especially in the aerospace, automobile and electronics industries in which production quantities are relatively low.
What’s an EDM Operator?
Electrical discharge machine (EDM) operators and programmers are typically responsible for performing G-Code programming to run wired EDM machines, as well as setting up and operating these units.
How are EDM electrodes made?
EDM is an acronym for electrical discharge machining, a process that uses a controlled electrical spark to erode metal. EDM electrodes include components made from brass, copper and copper alloys, graphite, molybdenum, silver, and tungsten.
What is working principle of EDM?
Working principle: The principle of working of EDM is based on the erosion of the material by repetitive sparks between the workpiece and the tool submerged in a bath of the dielectric medium. The working system is illustrated in Fig. 2.1. The workpiece and tools are two electrodes connected by D.C pulse generator.
What is EDM metal work?
Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges.
What is the basic principle of EDM?
Principles of EDM Electrical Discharge Machining (EDM) is a controlled metal-removal process that is used to remove metal by means of electric spark erosion. In this process an electric spark is used as the cutting tool to cut (erode) the workpiece to produce the finished part to the desired shape.
