“…Subsequently, this system was extended to the physical simulation for the prediction of the cutting forces based on the material removal rates [24]. For the optimization of the cutting parameters, Karunakaran et al [12] found good results compared to the experimental. In Refs.…”

“…The bijective surfaces are the most suitable ones. For a set of surfaces, it is not always [12] possible to machine all surfaces. For each line, all intersections with all surfaces are calculated and the highest intersection belonging to the skin of the part is retained thereby allowing the machining the outer envelope of the part [2].…”

“…Discontinuous and periodic nature of the cut in milling is also the cause of systematic vibrations of the system constituted by Part-Tool-Machine. Other investigations are related to the prediction of the cutting forces to optimize the cutting conditions [12]. Artificial intelligence is used to avoid collisions for multiaxis machines [13].…”

In industry, the evolution of productivity and quality of mechanical manufacture of complex shape parts (mold, automobile, form : : : ) is marked by the development of several machining simulation techniques for modeling and predicting the manufacturing process to represent the most realistic cut phenomenon. There exist several machining simulation techniques and touch various levels. Thus, this chapter summarizes the literature review and presents the techniques in a simplified scheme for the rapid exploration in this area, and in order to direct the reader to select an appropriate approach linked to a geometric or physical problem at a given scales in Part-Tool-Machine system. Particular attention is given to geometric simulation methods of the macroscopic scale; completed by brief comparison between models of workpiece representation for material removal process (Dexel, Voxel, Triple-Dexel).

“…This way, the mechanistic modeling module does what an adaptive controller will do with the help of force sensing. Therefore, the NC program optimization done using the Oct-OAC system is actually offline adaptive control (Karunakaran et al, 2010). For the computer animation processes, modeling, tracking and rendering are essential.…”

In order to improve capability of some traditional algorithms for 3D virtual reality animation, this article comes up with a new improved algorithm, which can improve traditional ones and is more suitable for 3-D graphic environment. There are two steps. The first step is to break down the entire 3-D scene and then setup the Octree structure. The second step is to transform the Octree onto 2-D plane, and write down nodes which are modified and then render the modified ones. Many experiments demonstrate the superiority of the algorithm. Especially, in the process of blanking, the quadrants are shown from far to near and achieve 3-D display more effectively, according to the given object and the location of view.

“…[16] showed the performance of the approach using a rotational tool in combination with a dexel model. A similar approach uses an Octree-based workpiece model to calculate the cutting forces and optimize the process related to the feed rate [9]. In machining of thin walled workpiece the consideration of the workpiece deviation is important.…”
