摘要:
本文提出一种针对碳纤维复合材料天线反射面的恒力控时加工方法.利用恒力控时装置,通过控制加工工具的加工时间,同时利用恒压气缸提供恒定压力输出,在碳纤维复合材料上进行加工实验,探究了磨粒粒径、压强、转速等工艺参数对材料去除效率的影响规律和去除函数的稳定性.结合工艺参数对材料去除效率的影响规律和去除函数稳定性的结果,通过多次迭代加工,使Φ390 mm碳纤维复合材料天线反射面从初始的面形精度117.798 μm RMS收敛到27.28 μm RMS,实现了碳纤维复合材料高精度的修形,证明了恒力控时加工方法对碳纤维复合材料天线反射面高精度加工的可行性.
Abstract:
This paper proposed a constantforce and timecontrolling machining method of carbon fiber composite antenna reflector. By using the constantforce and timecontrolling device, which controls processing time of the tool and provides stable pressure through the constantpressure cylinder, experiments were carried out on carbon fiber composites to research the influence rules of processing parameters, i.e., abrasive grain size, pressure, and rotational speed, on the removal efficiency and stability of removal function. Based on the influence rules of the processing parameters on the removal efficiency and stability of removal function, a Φ390 mm carbon fiber composite antenna was machined with the proposed method, and the surface accuracy of the antenna reflector decreased from 117.798 μm RMS to 27.28 μm RMS through multiple iterative processing, which achieved certain and high accuracy modification on carbon fiber composites and proves the feasibility of the constant-force and time-controlling method for machining carbon fiber composite antenna reflector.
