a product during the grinding operation. So, an Industrial experimentation is carried out on a grinding machine to eliminate the variations occurring on a product by making some changes on these causes. These four causes are the key parameters in a grinding machine. Hence, an effect can be surely achieved, once a change is made on these causes.
The class Surface Grinder Operation provides step-by-step guidelines on how to grind a rectangular workpiece. Grinding each side of a workpiece requires wheel dressing and other preparatory steps, and then roughing and finishing passes. Workpiece sides are numbered from 1 to 6 in order to track which sides must be ground perpendicular or parallel to one another.
