Dec 31, 2018 · Abstract. Many attempts have been made to achieve optical surfaces on hard and brittle materials by means of ductile diamond grinding using fine-grained diamond wheels. However, the large wear rate of the fine-grained grinding wheel, which is caused by dressing and by the grinding process, limited the achievable form accuracy and the maximum material removal volume, especially in case of ductile grinding …

mechanisms of material removal in the precisionproduction

Grinding of ceramics is often treated as coarse grinding dominated by brittle fracture or fine grinding, at very low removal rates, dominated by plastic deformation. Through a set of experimental observations and analysis, it is shown that in grinding of ceramics the abrasive/work interaction can be treated similar to well known chip formation models

Nov 21, 2018 · Alumina type abrasives are the most suitable for grinding high tensile materials such as steel and ferritic cast irons. The more friable types of alumina are preferred on harder steels and applications having large arcs of contact. Low tensile strength materials and non-metallic materials are most efficiently ground or cut with silicon carbide abrasive. The hardness of the material governs the …

nonuniform rational basis spline interpolation for off

Large-diameter aspheric mirrors made of hard and brittle materials suffer from low efficiency in the grinding stage, making them difficult to process. In this study, a nonuniform rational basis spline (NURBS) interpolation method is proposed and developed based on the grinding wheel path planning. The characteristic parameters of NURBS machining program are calculated to ensure the accuracy of
