Transient thermal analysis for grinding fabrication of hard and brittle material

One of the major problems that restricts the widely use of hard and brittle materials is the quality and efficiency of fabrication. To deal with this,improving fabricaiton efficiency and quality of hard and brittle materials needs to be quickly solved. To a large extent, high efficiency could imply the quality may get worse. Keeping up high efficiency and good quality seems to be contradictory in the meantime. Since the grinding thermal situation was one of the key elements that could affect the fabrication quality, this article aims to analyze the thermal situation in the process of fabrication of carbon dioxide and aluminum oxide by studying the relationships between grinding temperature and grinding parameters which include grinding wheel linear velocity, grinding depth and workpiece speed. In the meanwhile, it compared the thermal results between carbon dioxide and aluminum oxide in purpose of providing useful information and reference for fabrication.
