Cutting tools Machine Tools Lathe turning Drilling Milling Grinding Broaching, sawing, filing Nontraditional machining process (EDM) 3 Cutting Tool. In the context of metalworking, a cutting tool, is any tool that is used to remove metal from the workpiece in form of chips. It frequently refers to a tool bit.
abrasive machining processes
Difference between grinding and milling The abrasive grains in the wheel are much smaller and more numerous than the teeth on a milling cutter. Cutting speeds in grinding are much higher than in milling. The abrasive grits in a grinding wheel are randomly oriented . A grinding wheel is self-sharpening.

alloys featuring high strength characteristics. Used for grinding, milling and drilling small holes. Not suitable for manufacturing diese d) Electrical discharge machining (EDM): This is a widely applied and very useful method based on the erosion of metals caused by the discharge occurring between the electrode and the processed part.
Electro Chemical Machining(ECM)
The process is economical when a large number of complex identical products need to be made (at least 50 units) Several tools could be connected to a cassette to make many cavities simultaneously. (i.e. cylinder cavities in engines) Large cavities are more economical on ECM and can be processed in 1/10 the time of EDM.

The EDM process can be used in two different ways: 1. A preshaped or formed electrode (tool),usually made from graphite or copper, is shaped to the form of the cavity it is to reproduce. The formed electrode is fed vertically down and the reverse shape of the electrode is eroded (burned) into the solid workpiece. 2.
