|
As the subsequent course of Manufacturing ProcessesⅠ, in Manufacturing Processes Ⅱ, the theory and practice of injection molding and pressing, grinding, polishing, welding, joining, additive manufacturing, surface treatment, and related technologies will be taught. (Omnibus / Total 15 classes) (Wataru Natsu / 8 classes) Learn about the theory and practice of technologies of casting, die and mold used for mass production, injection molding, and plastic working. (Hiroyuki Sasahara / 7 classes) Learn about grinding and polishing, which uses abrasive grains to perform highly accurate machining, welding to join metals, additive manufacturing that creates shapes by adding materials, and surface treatments that give functions to the surface. (Omnibus / Total 15 classes) (Hiroyuki Sasahara / 8 classes) Students will learn the machining principle of cutting process of metals, ceramics, plastics, etc. And they also learn machine tools and the relationship with design of the products. (Wataru Natsu / 7 classes) (1) Learn the principles and features of electric discharge machining and electrolytic machining, in which the tool does not contact the workpiece, regardless of the hardness of the material, and the machining system including the machining power supply and control device. |
