“…The published algorithms can be classified broadly into local and global methods (Fan and Ball 2008). In the local methods (Vickers and Quan 1989, Bedi et al 1997, Rao and Sarma 2000, Jensen et al 2002, Yoon et al 2002, only normal curvatures of C (or W i ) and S are considered to orient C. The main disadvantage of the local methods is that there could still be rear gouging, and consequently a secondary iterative gouge-check and correction algorithm has to be implemented (Gray et al 2005). The global methods overcome the disadvantage by using an area of S beneath C to determine the orientation (Warkentin et al 2000, Gray et al 2003, Hosseinkhani et al 2007, Fan and Ball 2008.…”

Computer-Aided Design, Elsevier, 2008, 40 (10-11) Abstract: This paper deals with optimization of 5-axis trajectories in the context of high-speed machining. The objective is to generate tool paths suited to high speed follow-up during machining in order to respect cutting conditions while ensuring the geometrical conformity of the machined part. For this purpose, the optimization of the tool axis orientations is performed using a surface model for the tool path which allows integrating kinematical limits of the machine tool as well as classical geometrical constraints. The illustration of the optimization through an example highlights the gain in machining time, thereby demonstrating the feasibility of such an approach.

“…The G-code is derived from a toolpath The toolpath optimization usually aims to reduce the total length of the toolpath or the total machining time, maintaining the prescribed accuracy. Alternatively, the user may wish to improve the accuracy while keeping or even reducing the machining time [1,2].…”

Abstract. We propose a new framework for toolpath generation for 5 axis machining of part surfaces represented by the StereoLithography (STL) format. The framework is based on flattening the STL part and generation of curvilinear toolpaths adapted to the vector field of optimal directions. The experiments show that there is no universal sequence of steps applicable to every surface. However, a correct choice of the tools available within the proposed ACTframework always leads to a substantial improvement of the toolpath, in terms of its length and the machining time.6847 Stanislav S.
