摘要
磨头的工作函数是数控小磨头抛光工艺中的一个基本函数,有必要认真研究并确定其形状,优化其参数。在已有的圆形磨头的数学模型及工作特性研究基础上,通过引入修正因子,模拟得出了五角星形小磨头在行星运动和平转动两种运动方式下的工作函数及其特性曲线,分析并得出其优化后的工作参数。模拟结果表明,五角星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。
The working function of a polishing pad is an essennal tunctlon for the CNC polishing technique, and it is necessary to carefully study and determine its shape and optimize its parameters. Based on the research results of the known mathematic modeling and working characteristics of a round pad, by introducing a correction factor, the working function and its characteristic curve of the pentagon-shaped pad in conditions of the planet motion and translation are discussed, and the working parameters after optimization are analyzed and obtained. The simulation 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.
