Abstract:

The ideal and single roll-indent sawing machining model cannot explain the whole multi-wire sawing process because the environment of the process is not ideal and the requirement of process is not always the same. Based on multiple states existing in the movement of grind granule in multi-wire sawing process, this paper introduces integrated mechanical behavior of the granule-machining mechanism of grind granule determined by the hydrodynamics condition of the slurry fluid film. The granule in the status of semi-contact and full-contact uses roll-indent and roll-indent-chipping processes independently to implement sawing machining. That is the reason why multiple hybrid machining mechanics can explain the whole multi-wire sawing process. This mode is closer to the reality.
