MINIMIZING PROCESS OF SURFACE ROUGHNESS IN GRINDING WITH SUPER-SOFT GRADE RESINOID WHEEL

摘要

An improving process of surface roughness in cylindrical plunge grinding with a super-soft grade resinoid wheel is discussed, analyzing the ground surface profile, the topography of acting wheel surface and so on. Minimizing phenomenon of surface roughness, in which surface roughness decreases down to the minimum just after beginning of grinding, occurs remarkably in plunge grinding process with a super-soft grade resinoid wheel. And the phenomenon is useful for improving surface roughness by grinding. The number of simultaneously acting cutting edge is obtained by ground surface profile, topography of acting wheel surface and interference wheel arc length.
