Machine Structure - an overview | ScienceDirect Topics
In grinding, the workpiece, the grinding wheel, and the machine structure all deflect as contact is established. The real depth of cut, ae, is therefore smaller than the calculated depth of cut based on the feedrate. As in surface grinding, real depth of cut is affected by deflections, wheel wear, and thermal deflections.
