| Popis: | 99 There is a great demand of end mills for milling workpieces owing to the development of the aeronautical industry, die and mold processing, automobile parts, and 3C products manufacturing industry, etc. The advanced science and technology leads to products stand in need of high precision. High quality and high precision cutting tools are in great demand and more urgent for machining manufacturers. The geometric accuracy and the performance of machining of end mills essentially depend on the grinding procedures. It is an important issue how to effectively keep the grinding accuracy of the cutting tools. Therefore, this thesis aims to analyze and discuss the grinding characteristics and parameters when grinding tungsten carbide tools with diamond grinding wheels. Furthermore, we also proposed a tool surface roughness prediction system. In the experiments, a series of different grinding parameters have been utilized by the 33 and 43 factorial experimental planning for the same geometric profile of an end mill. The control factors in this study included the grain size, spindle speed, feed rate, and depth of cut. We used a five-axis CNC tool grinder to grind end mills, and measured the surface roughness and grinding ratio of the tools. The prediction system was developed by employing the abductive network for training of tool surface roughness. |
