Feb 21, 2015· FIG. DRILLING OPERATIONS 70. Grinding It is the process of removing material by the abrasive action of a revolving wheel from the surface of a work piece, in order to achieve required dimension and surface finish of the work piece. The wheel used for this purpose is called grinding wheel.
"Point of operations" means that point at which cutting, shaping, boring, or forming is accomplished upon the stock. (a)(2) "Push stick" means a narrow strip of wood or other soft material with a notch cut into one end and which is used to push short pieces of material through saws.
