| 摘 要： | 当前多丝切割的环境并非理想,加工要求并非相同.而理想及单一的“滚-刻”切割加工模型对整个过程难以解释周全.基于多丝切割中磨粒运行存在多种状态,指出研磨粒的综合力学行为(研磨粒的加工机理)取决于研磨液膜的流体力学条件,处于半接触和全接触状态下的磨粒,各自以“滚-刻”、“滚-刻-削”方式实施切割加工.故多模型混合加工可以较好地解释多丝切割加工的整个过程,多模型的混合加工模式更加接近实际状况.

| 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. |
