Abstract: Today most of the Computer-Aided Manufacturing (CAM) software are predominantly surface modellers. The toolpaths are generated mainly based on the areas that are to be manufactured. However, in many occasions, it is more desirable to make use of the information of the entire cut volume rather than just specifying the surfaces. This paper presents a Parametric Implicit Solid Modeller (PISM). Its Laplace-based solution enables the interior parameterisation of the entire cut volume. These developments lead to the realisation of a boundary-conformed morphing technology that can be applied to the unification of multi-stage manufacturing processes.

Keywords: CNC machining; morphing; multi-stage manufacturing processes; parameterisation; parametric implicit solid modelling; freeform surfaces; CAM; cut volume.
