Grinding is used to finish workpieces so that they meet the required surface finish quality. It rids unwanted material from the workpiece, like any rough texture that remains from previous machining applications. Grinding machines or tools use an abrasive wheel to remove metal from the workpiece. When the wheel rotates, it cuts material off …

Manufacture: Selection of correct grinding wheel is essential to all processes and applications. Low stress grinding (LSG) uses wheel speeds of about 20 m s-1 and can usually be done on conventional grinding machines in any of the grinding modes.; Most surface grinding operations use wheel speeds of 30–35 m s-1.; High speed (high …

Meanwhile, thermal and force-induced errors contribute to geometric errors. Moreover, the material removal rate of the grinding process is small, and the machine tool is worked in a thermostatic room with a constant temperature. Therefore, most of the existing studies focused on geometric errors of gear form grinding machine tools [11,12].
