Study on Energy Consumption Model and Cutting Parameter Decision Method of Machine Tool Oriented to Energy Saving Optimization

通过系统地研究机床运行全过程的能耗特性,构建出了工件加工全过程能耗切削参数模型。在此基础上,提出了一种面向高能耗、低排放的切削参数节能决策方法。首先根据加工过程不同时段能耗特性,分别获取能耗切削参数模型各个系数;然后根据切削加工条件分别构建出各个切削参数的单变量影响特性曲线和多变量影响特性曲面;最后根据得到的特性曲线和曲面对该加工条件下切削参数进行节能决策。为了验证该方法的可行性及准确性,采用实际加工过程对该模型及决策方法进行了验证。验证结果表明:该模型和方法能够在不同加工条件下对切削参数进行节能性决策,具有较好的应用前景。

In this paper,the energy consumption characteristics of the whole process of machine tool operation are studied systematically,and the cutting parameter model of energy consumption for the whole process is established.In addition,an energy saving decision method for cutting parameters with high energy efficiency and low emission is proposed.Firstly,the method for acquiring the coefficients of the model is introduced based on the energy consumption characteristics in different processing periods.Then the univariate influence characteristic curve and the multivariate influence characteristic surface of each cutting parameter are constructed respectively.Finally,the energy saving decision can be made under the given machining conditions.In order to verify the feasibility and accuracy of the method,the case study is conducted,the results indicate that the model and method can be used to make energy-saving decisions on cutting parameters under different machining conditions and has a good application prospect.
