抄録

Recently, the following two new items are strongly required for coil springs used for 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. For these requests, the geometry of the spring became complicated. Therefore, it was difficult to produce the spring correctly to the various demands. The developed CAD-CAM system is capable of materializing the designed geometry of the spring without the help of worker's 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. In the case of creation of NC data, this system makes reference to a database of forming machines and spring materials which affect the dimensions of the product. It also includes the prediction of the geometry change in the process of presetting and tempering.
