Machining. Machining is manufacturing process that involves removing materials using cutting tools for getting rid of the unwanted materials from some workpiece and converting it into the shape you desire. A large piece of stock is used for cutting the workpiece. The large stock might be in any shape such as solid bar, flat sheet, beam or even hollow tubes.

Grinding Machine Definition: A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial.. It is a process of metal cutting by using a rotating abrasive wheel from the surface of the workpiece.. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.
Grinding machines, like broaching machines, operate over a range of speeds depending on the type of machine being used.These range from approximately 1250 to 2000m min −1, although in high-speed grinding speeds of up to 5400m/min are achievable (Schey, 1987).The two most common grinding applications are cylindrical grinding and surface grinding.
