针对机械加工中切削热和切削温度的问题,采用实验数据、解析计算、数值分析的方法,提出了将切屑带走的热量和传入刀具的热量都传入刀具,再将切屑带走的热量看作对流换热形式将热量从刀具上散发出去的方法,来分析热流量和刀具-切屑接触面温度。结果表明,运用这种方法不仅可以分析传入刀具的热流量和刀具-切屑接触面温度,也可以作为优化切削参数。 Aiming at the problem of cutting heat and cutting temperature in machining, experimental data, analytical calculation and numerical analysis are put forward to transfer the heat removed by the chips and the heat introduced into the cutter into the cutter, Think of convection heat transfer as a way to dissipate heat from the tool to analyze heat flow and tool-chip contact surface temperature. The results show that using this method can not only analyze the heat flow into the tool and the tool-chip contact surface temperature, but also can be used as the optimal cutting parameters.
