The wheeled polishing structure with cylinders based on industrial robot is established by combining the advantages of robot control and wheeled polishing technology. It can flexibly adapt to the surface shapes of aspherical, meanwhile, based on the friction between the polishing wheel and the working surface, a high-precision surface is obtained under the control of the precise pressure. Based on Preston's Formula and Hertz's Contact Theory, using MATLAB to perform Numerical Simulation to verify that the downforce meets the Gaussian distribution, which demonstrates the feasibility of the structure. Then this paper uses MATLAB to design code programming and a reasonable running track.
Chromatic confocal 3D profilometer has widely used in science investigation and industry fields recently for its high precision, great measuring range and numerical surface characteristic. It can provide exact and omnidirectional solution for manufacture and research by 3D non-contact surface analysis technique. The article analyzes the principle of surface measurement with chromatic confocal technology, and provides the designing indicators and requirements of the confocal system. As the key component, the dispersive objective used to achieve longitudinal focus vibration with wavelength was designed. The objective disperses the focus of wavelength between 400~700 nm to 15 mm longitudinal range. With selected spectrometer, the resolution of chromatic confocal 3D profilometer is no more than 5 μm, which can meet needs for the high precision non-contact surface profile measurement.
