机加工过程一类能耗估算模型

An Estimation Model for Energy Consumption in Machining Process

针对机加工过程中的能量消耗,将机加工过程的能耗分为固定能耗、空载能耗和切削能耗三个部分,推导构建一类机加工过程的能耗估算模型,并通过实验完成能耗模型参数的确定.最后以实际铣削加工案例分析表明,在给定工艺参数情况下,该模型能够较为准确地计算机加工过程中的能耗,为后续的工艺参数优化及工艺决策奠定基础.

According to the problem of energy consumption of machining process, the energy consumption could be divided into three parts： fixed energy consumption, non-load energy consumption and cutting energy consumption. An energy consumption estimation model was proposed, and the parameters were determined by experiments. Finally, an actual milling case indicated that the model can provide a reliable prediction of energy consumption for given process parameters, which would be the foundation of the subsequent process parameters optimization and process decision.
