“…The authors present the decomposition algorithm of the Octree model into three Quadtree models which store the geometry along the three main directions. 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 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).

“…Chiou and Lee (2002) constructed the cutter's swept envelope and applied it to NC verification. The stencil buffer sweep plane algorithm (Bohez et al 2003), octree-based voxel data structure (Yau and Tsou 2009) and octree solid representation (Karunakaran and Shringi 2008) have been employed to develop the algorithm for 5-axis machining verification. The second research issue on manufacturability research of multi-axis surface machining focused on determining the optimal tool orientation and preventing error occurrence during tool path planning (Chiou and Lee 2005).…”

Multi-axis machining of a complex surface is not only efficient but also reduces workpiece set-up errors. However, engineers usually rely on experience when determining set-up orientation and often cannot finish complex surfaces in one set-up. In this paper, a rational evaluation method for workpiece orientation and configuration of machine tool before tool path planning is proposed to increase the efficiency and reliability of process planning.By incorporating the visibility cone into workspace analysis, a software module is constructed in this research for optimum workpiece orientation and configuration of machine tool. First, the configurations of three-, four-and fiveaxis machine tools were synthesised, and the workspace was then analysed using form-shaping function. Both position vector and normal vector of each point along the u and v directions in the machining surface were employed to calculate the visibility range as the point of the visibility cone. In 3-axis machining, all normal vectors of the surface were projected on a unit sphere. All normal vectors were ensured to be within the visibility range of the ballmill cutter as the workpiece set-up orientation changed. In 4-axis machining, the intersection between the visibility cone of each point and the workspace was obtained by changing the set-up orientation. In 5-axis machining, according to different workspaces of 5-axis machine tools, the visibility range of the machining surface was determined to yield the intersection between the visibility cone and the workspace by changing the workpiece orientation.The proposed method for evaluating manufacturability has been demonstrated to generate optimum workpiece set-up orientation and the suitable configuration of machine tools. Tool interference with workpiece surface can be avoided, which can help improve the planning of tool path.

“…As a result, the swept volume method can lead to reduced computation time and provide better and more reliable distance information. The representation of volumes swept out by moving solids (Xia and Ge, 2001;Blackmore and Leu, 1992;Leu et al, 1986;Wang and Wang, 1986) and its applications (Zhu et al, 2009;Karunakaran and Shringi, 2008;Li et al, 2005;Weinert et al, 2004;Hasegawa et al, 2003;Oliver, 1992;Ganter and Uicker, 1986) can be found in several paper in the literature. One early major study among them was an analytical technique to compute swept volumes for real time verification of NC programs was developed by Wang and Wang (1986).…”

The recursive quadratic programming (RQP) technique has been successfully applied for the motion planning problem. This paper inherits the RQP optimization formulation to solve collision-free motion planning problems. The focus of the paper is to develop a more accurate approach to represent the swept volume based on Hermite interpolation. The non-convex swept volume may be described by parametric representation. Based on this idea, the non-convex limitation of the motion planning by the previous RQP technique can be overcome and it has yielded accurate answers in distance calculation. Also, have been presented to illustrate and demonstrate this approach in the paper.
