Optimization of Grinding Conditions of Axisymmetric Aspherical Grinding

With the recent increase in size and image quality of optical equipment, there is a strong demand for higher precision aspherical lenses. Generally, an glass lens or its mold formed by grinding then finished polishing. Since shape accuracy deteriorates this polishing process, it necessary to keep amount small. Therefore, desirable optimize conditions reduce surface roughness. In paper, axisymmetric surface, maximum height roughness ground analyzed theoretically utilizing statistical theory. From view point relationship between grain cutting direction workpiece feed direction, can be classified into parallel cross grinding. And found that suited
