The ground cutting tools are used for chipping during metal, wood and plastic processing.Worn tools can be restored to the correct cutting geometry through a process called dressing. This regrinding restores the quality of the cutting edge, thus improving both the cutting quality of the worn tool and the durability and thus the economy of the tool.

capabilities and the nature of the work. The utility grinding machine consists of a horizontally mounted motor with a grinding abrasive wheel attached to each end of the motor shaft. The electric-motor-driven machine is simple and common. It may be bench-mounted or floor-mounted.

A grinding machine is a production machine tool used in the manufacturing industry in which the grinding wheel is attached in the tool post and the workpiece is fixed to the work table and when the operation starts it removes the unwanted material to get the desired surface finish, correct size, and accurate shape of the workpiece.

Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can
