Surface Grinding is a manufacturing process which moves or grinding wheel relative a surface in a plane while a grinding wheel contacts the surface and removes a minute amount of material, such that a flat surface is created. The term surface grinding designates any process which accurately processes or grinds a surface.

grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10. • Determine the grinding force and force per grain. • Determine the ...

For surface grinding operations, the process parameters, i.e. the linear feed, the cross feed, and the depth of cut, have a direct influence on the roughness of the ground surface. Higher values of any of them would result in a higher material removal rate, and therefore, a higher rate of generation of thermal energy.

Similar to calculating other times, the general formula for CNC machining is distance or length divided by rate or speed. When it comes to machining time calculation, the formula is as follows: Machining Time = Length of Cut (mm) / Feed (mm per revolution) x Revolutions Per Minute. Revolutions Per Minute = 1,000 x Cutting Speed (mm per minute ...

Recommended cutting speeds are from 1,000 to 1,300 sfm. Common feeds for "beauty face" are from 0.004 to 0.006 ipr. PCD-tipped grooving-type inserts are applied. A 45- to 55-hp machine tool's maximum spindle speed is 3,000 rpm. Okuma makes the most common machine for this operation.
