where R is the radius of the work piece.. The main mechanism of grinding chatter is the regenerative effect which comes from the periodical variation of the chip thickness on the work piece or grinding wheel surface [].The oscillating chip thickness gives rise to oscillating grinding force which acts upon the machine structure.

is loose abrasive grinding. This involves using various grit sizes mixed with water (this mixture is called a slurry) to remove glass. The larger the grit size, the more glass is removed, resulting in a faster removal rate. However, a rougher surface will be produced. Therefore, generating begins with large grit sizes of up to 100-200µm and
