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.
Highlights
The purpose of the present research consists in working out of a way of the combined peripheral grinding of the planes [10], characterised by higher productivity of a production operation at maintenance of demanded values of a deviation from planeness of processed surfaces
Porous and discrete grinding wheels provide considerable decrease in thermal stress level of processes, raise of productivity and physics-mechanical characteristics of the processed blanket [5-7]. Together with it named above research do not mention a question of decrease in an auxiliary time at performance of preliminary and definitive grinding, that reduces productivity of machining processes
Combined grinding is characterized by a higher productivity by comparison with the traditional grinding, because it allows to exclude or substantially reduce the auxiliary time for technological operation: the replacement of the coarse by the fine-grain grinding wheel, its truing and the adjustment of the machining tool for a size and etc
