In the manufacturing of high value-added products such as molds, aircraft parts, and medical devices, cutting processes using numerically controlled machine tools are primarily employed. In recent years, there has been a demand to further enhance the intelligence of computer-equipped numerically controlled machining tools to create shapes that include complex structures and freeform surfaces defined by CAD software, as well as to develop functions that allow for processing in response to variations in various phenomena.
In our laboratory, we are conducting research in collaboration with various companies on computer-aided techniques for cutting processes that manufacture high value-added metal parts with high shape accuracy by partially removing material. This involves predicting in advance the tool movement paths, tool postures, and the state of material removal by the cutting edge of the tool through simulation, in order to optimize the operation of numerically controlled machine tools such as machining centers and multi-tasking machines.
We are also working on the development of new technologies such as skyving, a next-generation gear cutting technique, and cutting using vertical articulated robots.
