Оценка ресурса сборного комбинированного инструмента по временной стойкости и количеству обработанных отверстий

Abstract

An example is given of calculating the service life of a combined tool for machining a stepped hole, which proves the inappropriateness of assigning tool cutting modes to a cutting element with a minimum minute resource. It is proposed to pre-assign cutting modes for tools of the same type according to the cutting element with the longest cutting length, establishing a replacement schedule for the element with the smallest number of machined holes during the period of trouble-free operation.
