During the grinding process, there is a slight amount of deformation in the direction of normal grinding force, so the influence of deformation on grinding force can be offset by controlling the feed amount of robot in this direction. Let the feed amount (Delta x = delta_{x} left( t right)), then Eq. can be written as,

Chrome cast iron grinding media in spherical ("ball") or ovoid shape, with a diameter of 12.7 millimetres (½ inch) to and including 76.2 millimetres (3 inches) within tolerances of 5 percent (5%), with an alloy composition of 10 percent or more (≥ 10% of total mass) chromium ("Cr") content and produced through the casting method, originating in or exported from India.

During grinding, the force of the grinding wheel pushes the workpiece into the regulating wheel and against the support. The regulating wheel determines the workpiece's rotational speed. Tilt it a few degrees and the workpiece will be pulled through the wheels and out the back of the machine, a technique known as through-feed grinding.

test surface using a static force of 3000 kg (=29.42 kiloNewton) for at least 10 seconds for steel and measuring the diameters of the indentation left on the surface by means of a graduated low power microscope. The result is either calculated using a given formula (see at the end of this section) or looked up on prepared Tables.

Fine grinding produces a surface with little deformation that can easily be removed during polishing.
