Material removal rate in grinding is usually quoted in terms of removal rate per unit width of grinding contact. Removal rate per unit width is known as specific removal rate Q′. Using the specific removal rate reduces the number of variables and allows direct comparison of removal efficiency across a wide range of operations (Fig. 2.7).

For most tool post grinding operations, the material removal rate is dependent upon three factors: work diameter, depth of cut, and traverse rate. The removal is expressed in cubic in./min. and can be found using the following equation: Removal Rate = Traverse

Specific Material Removal Rate for Conventional Grinding Processes As the part geometry and process kine-matics are easy to follow, surface-periph-eral-traverse grinding is chosen as an example for calculating the specific mate-rial removal rate for conventional grind-ing processes. The process is applied for grinding large surfaces and its

01-11-2013· The material removal rate for EDG has been modelled based on material removal rates for grinding and EDM processes. • The dominance of machining mode (grinding, EDM or combination of the two) has been identified for MRR. • The white layer has been considered to be proportional to discharge energy of a spark. •

The specific material removal rate appears to be the product of the depth of cut and the feed rate. "Specific" refers to normalization by the width of the cut. From a quick search at Google Books, this definition appears, for example, in: Li's "Efficiency of Manufacturing Processes" Klingelnberg's "Bevel Gear: Fundamentals and Applications"

Unlike normal grinding, which is used primarily to finish surfaces, CFG is used for high rates of material removal, competing with milling and turning as a manufacturing process choice. Depths of cut of up to 6 mm (0.25 inches) are used along with low workpiece speed.

In this paper, the formula of material removal rate (MRR) in wafer rotation grinding process is deduced based on kinematics. The main effect on MRR of the grit size and the process parameters, including the rotational speed of the cup grinding wheel, the down feed rate of the grinding wheel spindle and the rotational speed of the chuck table, is both theoretically and experimentally investigated.

Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid. Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour
