| 摘 要： | 在分析机床进给系统各部件功率特性的基础上建立了进给系统的功率模型，并运用此模型分析了进给系统的空载功率特性及其主要影响因素。理论分析表明，进给系统的空载功率是关于进给速度的单调递增二次函数，同时分析表明进给速度和负载质量均影响进给系统的空载功率，但负载质量对空载功率的影响极小。最后在3轴数控铣床上进行了实验研究，结果表明理论分析的有效性。

| Abstract: | A power model of a CNC machine tool feed system is proposed based on analyzing the power characteristic of each component in the CNC machine tool feed system. And the tarepower characteristic and its dominant affecting factors are analyzed by using the power model. The analysis results show that the tarepower of feed system is a monotone increasing quadratic function in term of the feed speed. Meanwhile, the feed speed and load mass both affect tarepower, but the influence of load mass is minuteness. Some experiments are conducted on a 3-axis CNC milling and the experimental results justify the theoretical analysis. |
