New Technology of Manufacturing for Coil Springs Used in Automotive Suspensions 2002-01-0318

Recently, the following two new items are strongly required for coil springs used in automotive suspensions. One of them is the control of the force action line of the spring. The second item is to design the geometry of the spring so that the spring can be installed within the space allowed. In order to meet these demands, precise design and production technology is required. However, it has been difficult to produce the springs exactly as they are designed. The developed CAD-CAM system is capable of materializing the designed geometry of the spring without the help of workers' skills and experiences. This system allows us to automatically generate NC data for coiling from the geometry of the spring obtained by the finite element analysis.
