| 中文摘要: |
| 数控小磨头抛光技术中,磨头的工作函数是加工过程中的一个基本函数。在已有的圆形磨头的数学模型及工作特性研究基础上,讨论了椭圆形小磨头在行星运动和平转动两种常用运动方式下的工作函数及其特性曲线,分析并模拟得出其优化后的工作参数。结果表明,椭圆形磨头在常用运动方式下的工作特性曲线均具有中心最大峰值,近似于高斯分布,具有良好的材料去除能力。 |

| In the Computer Numerical Control (CNC) pad polishing technology, the working function of the pad is an essential function during fabricating the workpiece. Based on the research results of the known mathematic modeling and working characteristics of a round pad,the working function and its characteristic curve of an elliptical pad in conditions of planet motion and translation are discussed, and the working parameters after optimization are analyzed and obtained by simulation. The results show that the working characteristic curve of the pentagon-shaped pad has the central peak in the conditions of both commonly-used motions, which similar to the Gauss distribution, and the pad has good material removal ability. |
