With increased angle, quicker rounding occurs, but it also weakens the blade rigidity. The most common top angle used in centerless grinding is 30 degrees. As the diagram below indicates, lower angles are used when grinding heavy workpieces, which help minimize vibration. Workrest top angles typically range from 45 degrees down to 20 …

The basic process parameters in grinding processes are the cutting speed v c, the feed velocity v f, the depth of cut a e, and the width of cut a p (see Fig. 1, see also Denkena and Tönshoff 2011 ). The cutting speed is in general equal to the circumferential speed of the grinding wheel. The feed velocity is oriented in feed direction.
Cryogenic grinding is most effective when the product is sprayed with liquid nitrogen as it is being conveyed and introduced into the Attritor.
