英文要約Title:Construction of conceptual design methods using topology optimization for rapid and creative product development

Nagase integrex co., ltd takes the role in the development of ultra-precision processing technology in the implementation no.3 "Development of device design and device manufacturing technology by the device design method". In 2015, we introduced an ultrasonic elliptical vibration cutting device, which has achievements direct processing with glass material and steel material by diamond bite, and examined mirror-finishing process with STAVAX material using it. After verified the function of itself and ultrasonic elliptical vibration cutting method, we also verified the process with insulation material and copper-plated insulation material. We selected tools for processing considering the groove pattern (several tens μm to 200μm width and target accracy is ±10μm) and structure needed for the final product and characteristics of the material which come as the result of the discussion with another project participants last year. Furthermore we manufactured a simultaneous 6-axis ultra precision cutting machine to verify process on free-form surface.
Grooving on free-form surface, machine must have 6-axis and control them all at a time. However, such software suitable for the 6-axis structured machine does not exist at a market, creating processing program for the machine is extremely difficult. Thus we developed a method to control the 6th axis (controls tool to processing direction) by monitoring the other five axis in real time and calculating its movement automatically. Using this method, required software function is 5-axis control at a time. Therefore we introduced simultaneous 5-axis CAM software.
Verification of the electromagnetic device fabrication method using three-dimensional modeling, 6-axis cutting machine and simultaneous 5-axis CAM software is scheduled from next turm. We are planning to introduce a multi-component dynamometer to measure cutting force of precision machining and promote research and development.
During copper-plating and the insulating material processing using the ultrasonic elliptical vibration cutting device, the tool chipping or breakage occured. This is concluded that cracks preexixting the tool is caused to undergo influence of heat. Considering the overall like processing condirions, it is necessary to suppress the thermal effect of the tool and the machine surface. Therefore, verification using the ultrasonic elliptical vibration cutting device will be taken over next year.
