Surgical simulator reconstructs the deformation and the elasticity of the organs by software algorithm. As this calculation is complicated, phase-lags or the sudden elasticity would arise when we press the surface of the organ models with our fingertips. In this paper, we propose a method to solve these problems by correcting the computing time delay using the nonlinear estimation of the finger position and smoothing the elasticity value using the cubic spline interpolation. Further, experiments by simulation carried out to ensure the validity of this method.

5-axis control machining has the potentials of producing workpieces with complicated shape efficiently and accurately in comparison with conventional 3-axis control one. NC data for 5-axis control machine tools are in general offered by CAD/CAM systems, which create collision-free CL data from the workpiece and tool shapes. The post-processor plays an important role of providing actual NC data from CL data, taking account of a variety of 5-axis control machine tool structures. The study deals with the proposal of how to construct generalized post-processor, independent of the machine tool structures, by applying a concept of the form shape function, which represents the linkage and kinematics of control axes. As the result, the validity of the proposed generalized post-processor is experimentally confirmed.
