Deviation from flatness of surfaces after combined peripheral grinding

Abstract

A new method of combined flat peripheral grinding is examined, which allows to carry out simultaneously preliminary and final machining of the planes without replacing the coarse with the fine-grain grinding wheel, to eliminate the auxiliary time for the tool replacement, to correct it and set the grinding equipment in order to accomplish the given size. An experimental multifactor model which relates the surfaces flatness deviation with independent factors of the combined grinding process is established on the basis of which it is possible to assign the cutting conditions that provide the required flatness with the greatest possible longitudinal and cross-feed of the blank.
