Frames supporting the processing units of ful-color copiers and printers require high rigidity and accuracy. Traditionally, the general practice was to add rigidity to parts of the frames. A product recently put into volume production suffered a significant problem of frame shape deformation. To solve this problem, the frame shape was optimized by quality engineering and CAE using the finite element method. Six test pieces were optimized in this way and compared with each other to determine the degree of quality. The individually optimized test pieces were mated with an actual machine and further optimized for minimum deformation. As a result, a frame shape having 0.7-mm deformation under test conditions alld 0.16-mm deformation in actual machine conditions was obtained. This method also reduced the development cost by 45% and the number of process steps by 37%.
