What is Machining? | Casting Blog - Reliance Foundry Co. Ltd

Casting is the process of filling a mold with a molten alloy and letting it cool. Forging works metal, changing the material's properties by applying compressive forces that alter the metal lattice. Operations like bending, twisting, pounding, and folding are common in forging. Machining carves, grinds, cuts, bores, or otherwise shapes metal.

The surface finish generated would depend upon grain size used. The fine grain will take a very small depth of cut and hence a better surface finish is produced. Fine grains generate less heat are good for faster material removal. Fine grains are used for making the form grinding wheels. Coarse grains are good for higher material removal rates.
