通过监测系列锯切试验的主轴功率，分析锯切过程空载功率、有效锯切功率的变化规律，并结合材料去除率进行分析。结果表明，空载功率随锯切线速度增大基本呈线性增大。有效锯切功率随材料去除率呈近似线性增大。能效系数随材料去除率增大而增大，去除单位体积材料总能耗系数随材料去除率增大呈先快速后缓慢的减小趋势。总体上讲，高线速度锯切工艺直接增加空载功率，并不节能，适当提高材料去除率有利于低能耗加工。

Experiments of sawing granite with diamond circular blades were conducted to study the energy efficiency of circular sawing.In sawing,the power consumed by machine spindle can be classified into idle power and active sawing power.The idle power increased linearly with the in-crease of the linear sawing speed of the blade.The active sawing power increased nearly linearly with the increase of material removing rate.The energy efficiency coefficient increased with the in-crease of the material removing rate,but the overall energy consumption coefficient of removing per unit volume materials decreased quickly at first and then gradually slowed down.The results indicate that the high linear speed sawing improves idle power but does not lower energy consumption,that raising the material removing rate in a proper manner is condusive to low power processing.
