“…The development of advanced optoelectronic and astronomical devices highly demands for optical components and molds with spherical, aspherical and freeform surfaces with high profile accuracy and excellent surface finish. [1][2][3][4] Most of these components and molds have to be machined by abrasive processes with diamond wheels due to their hard-brittle materials property, such as ceramics, cements, optical glasses and crystalline materials. [5][6][7] The arc-shaped diamond wheels with precision profile were usually adopted for ultra-precision grinding of spherical, aspheric and free-form surfaces.…”

To realize the efficient and precision truing of arc-shaped diamond wheel, a novel on-machine precision form truing of arc-shaped diamond wheel is proposed utilizing rotary green silicon carbon rod, and online monitoring of the truing process by acoustic emission was studied. Through this truing method, any required radius of wheel arc profile could be formed by programmed truing paths; meanwhile, the vertical direction position error of the wheel center could be corrected after truing. In order to improve the truing efficiency, the acoustic emission signal was processed to monitor the truing process, and the AE rms threshold of judging the finishing truing time was obtained.

To realize the high-efficiency grinding of the aspheric surfaces on monocrystal silicon, a novel on-machine truing method for the resin-bonded arc-shaped diamond wheels was proposed utilizing rotary green silicon carbon rod, and then the high-efficiency grinding of the aspheric surface was performed. First, the principle of mutual-wear for truing arc-shaped diamond wheel was introduced, and the truing performance was studied. The experimental results showed that the top morphology of the trued arc-shaped wheel was precise and smooth, and the run error on the top of the trued arc-shaped wheel was reduced from 41 to 10 µm after truing. Furthermore, high-efficiency grinding experiments revealed that the surface quality of the aspheric surface increased with the increase in the average material removal rates.

“…In addition, although laser profiling could achieve higher accuracy, during ultra-high precision grinding, a surface circular runout of approximately 2 m is normally required. For example, Zhao et al [7][8][9] of the Harbin Institute of Technology used a cup-shaped diamond wheel combined with inprocess electrolytic sharpening to dress 91-m diameter grains of an electroplated diamond wheel. The circular error was reduced to within 2.5 m, and the surface roughness of the workpiece ground by the wheel was 20 nm.…”
