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).

Abstract. High-speed (up to 127 m/s) and high material removal rate grinding experiments were conducted using a vitreous bond cubic boron nitride (CBN) wheel to investigate the effects of material removal rate, wheel speed, dwell time and truing speed ratio on cylindrical grinding of silicon nitride and zirconia.

Metal removal rate is an important performance factor to be considered in grinding process. Research activities that include experimental work and statistical analysis help in improving quality ...

This research paper attempts to optimize the effect of input parameters to minimize surface roughness and maximize the material removal rate in cylindrically grinding of EN 47 steel material. Taguchi L18 (2)¹, (3)5 orthogonal array or mixed level of parameters have been applied to experimental design with the help of mini tab software. The result reveals that grain size and work speed are the ...

Removal rate is proportional to infeed rate, v f, in plunge centerless grinding. For the particular conditions, the optimum workspeed is seen to be given approximately by v w = 0.25 m/s, when grinding with medium carbon steel, AISI 1055, or with gray cast iron. At this workspeed, the infeed rate could be increased up to the maximum power ...

High removal rate grinding of alumina and alumina–titania was investigated by Yina et al. with respect to material removal and basic grinding parameters. The results show that the material removal for the single-phase polycrystalline alumina and the two-phase alumina–titania composite revealed identical mechanisms of microfracture and grain ...

Electrical discharge machining is one of the earliest nontraditional machining, extensively used in industry for processing of parts having unusual profiles with reasonable precision. In the present work, an attempt has been made to model material removal rate, …

A grinder with a low-removal-rate grinding wheel can face significant challenges working with stainless steel. Again, excessive heat can cause bluing and change the material properties. The goal is to keep stainless steel as cool as possible …
