The sheet parts are formed with dies conventionally. But this conventional forming process is not suited to small volume and varied production for the reason of high cost. For the solution of this problem, a new forming process, which is called CNC incremental sheet forming, is being introduced. This process can form sheet parts without die, and is very well suited to small volume and varied production in space flight and automobile. In this paper, dieless CNC forming system based on a machining center is developed. A special device to grasp and pull the blank sheet built in the machining center and tool path generation S/W from STL file of 3-D model are developed. Several sheet parts are incrementally formed to verify the effectiveness of the developed system.

When make most products, the standard is made by standard of the young. These are not proper standards for making the supplies for seniors. To adapt the standards of the aged, it is necessary to construct the database which is based on the survey for producing supplies for seniors. In this study, wish to measure life eyesight and ability by color-distinguish that use Flash because uses LandoltC ring and dark adaptation that use contrast and glare to construct sight function measurement system doing to elderly, and construct database because uses measured data.
