Abstract

The paper presents an efficient realtime simulator for 3-axis milling processes. In this system, solid modeling is performed using isometric projection with a z-map structure. As a result, all the solid elements are either fully exposed or fully hidden, and they are well arranged and symmetrical. These characteristics make visible surface determination for the raster display more efficient, and they reduce the memory requirements considerably. As a result, this efficient and realtime voxel-based model can simulate NC milling processes satisfactorily even in personal computers, without the aid of extra hardware devices or coprocessors. This simulation system will be useful to NC programmers and machining operators for identifying programs and checking gross programming errors visually.

    [Show abstract] [Hide abstract] ABSTRACT: The simulation techniques development for multiaxis machining is key to the evolution of productivity and quality in the manufacture of mechanical parts with complex shapes (aerodynamic shapes, molds, etc.). The machining simulation representing accurately the cutting phenomenon is indispensable. However, this technique is penalized by the lack of knowledge of the cut. This field is wide and deals with various aspects. In this paper, the main machining simulation techniques are classified by category (geometrical and physical), by scale (multi-scale approach) and Part-ToolMachine (dynamic and geometric) system. In the end, particular attention is given to geometric simulation techniques at macroscale.

    • "Geometric simulation of the material removal process is an essential aspect in CNC machining simulation. Three groups of modelling methods have been applied, namely, the solid modelling and approximation methods9101112, the discrete vector intersection (DVI) methods [13,14], and the spatial partitioning representation (SPR) methods using dexels151617. Using the approximate solid modelling methods and the DVI methods, the geometric simulation process can be simplified by converting the 3D models into 2.5D objects. "
    [Show abstract] [Hide abstract] ABSTRACT: CNC machining simulation has been developed to validate NC codes and optimize the machining process. Conventional simulation systems are usually performed in virtual environments, and this has the limitation that the operator needs to transfer the knowledge from the software environment to the real machining environment. The ARCNC system is proposed in this paper where the operator can observe in situ simulation between the real cutter and a virtual workpiece. The system design and the research problems addressed are discussed in this paper, including the tracking and registration methods and the physical simulation approach based on an enhanced dexel model.
