Most of CAD/CAM systems for CNC lathe have been developed as the form of automatic programming systems which can generate autormatically or interactively the NC code from the process sheets and design drawings of products. But these systems have some problems during the modeling process of product shap since the shape is not described by the features intimate with system users such as chamfering, rounding, groove, arc and so on. Therfore, in this paer, the feature based CAD/CAM system for CNC lathe which is able to represent the truned product shapes by the typical features, is developed. Especially the system has the various capabilities such as the automatic determination of cutting domains, the automatic generation of CL data and NCcode, the real time cutting simulation for verification of NC code, the DNC operation and so on.

Recently, the various driving simulator have been used widely to analyze the handling performance of vehicle and to verify the motion control algorithm of vehicle. In this study, a driving simulator based on the 20-DOF vehicle model is realized to estimate the handling performance and stability of a four-wheel-steering and/or four-wheel-driving vehicle. Especially the DC motor controlled four-wheel-steering actuator is modelled in order to reflect the effect of the responsiveness of actuator on the handling performance and stability. And the realized simulator can be applied to develope a real time simulation system for designing and testing the real vehicles.<br/>
