Achievable surface finish EDM vs ID grinding

So, quite simply, the question has arisen as to by what process produces the best, highest quality hole between wire EDM, and ID grinding; roundness and surface finish. The material in which the holes are to be finished is a silicon carbide based ceramic; so regarding the tooling for the ID grinding operation, it would be diamond.

Electrical Discharge Machining. How EDM Machine Works?

The term EDM stands for Electrical Discharge Machining. You all know about conventional machines like lathe, milling, grinding, or drilling where the cutting tool is always harder than the work-piece; also the cutting tool applies the force to remove the material from the work-piece during machining.. The Electrical Discharge Machining (EDM) is an unconventional …

Choosing EDM machining in the manufacturing process ...

Choosing EDM machining in the manufacturing process. Manufacturing and design engineers resort to Electric Discharge Machining when conventional turning, milling, broaching and grinding methods cannot be applied. To determine if EDM is the right approach for your application, one needs to evaluate certain parameters and advantages:

Machining - Material removal processes

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which …

Wire EDM Processing: Problems and Solutions 101 - SANS

Wire EDM Processing: Problems and Solutions 101. 1. Wire Broken. (1) Poor discharge state—–lower the value of P. If the value of this value is greatly reduced and the wire is still broken, consider reducing the value of I until the wire is continuous. This operation will reduce the processing efficiency.

What is Electrical Discharge Machining (EDM) Process and ...

Electrical Discharge Machining (EDM) is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges (sparks). It was first observed in 1770 by Joseph Priestley. He was …

ELECTRICAL DISCHARGE MACHINING (EDM)

Application of EDM The EDM process has the ability to machine hard, difficult-to-machine materials. Parts with complex, precise and irregular shapes for forging, press tools, extrusion dies, difficult internal shapes for aerospace and medical applications can be made by EDM process. Some of the shapes made by EDM process are shown in Figure 3.

Optimization of EDM Process Parameters: A Review of ...

The various process of EDM: die sinking EDM, wire EDM (WEDM), EDM milling, and wire electrical discharge grinding (WEDG). Principle behind EDM process is thermo-electric source between the job and an electrode. Majorly electrical discharge machining parameters are usually evaluated on the basis of surface roughness (SR), MRR (MRR), cutting ...

EDM Process | Types of EDM Machining & Applications

EDM stands for E lectrical D ischarge M achining. It is a precision process of creating high voltage sparks to vaporize metal. In this process, a metal workpiece that is to be machined is clamped into machining bed. This material must be conductive and electrically grounded to complete the electrical circuit.
