Material Removal Rate - an overview | ScienceDirect Topics

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).

A killer combination for ideal grinding conditions ...

Grinding is a fairly straightforward process, combining four key elements: a grinder, a grinding wheel, a metalworking fluid, and a part. Two of these components are fixed — the grinding machine, which is rather expensive to replace or modify, and the part, which must …

Factors affecting proper coolant application when grinding ...

Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual stresses.
