Arc-intersect method for 5-axis tool positioning

Arc-intersect method for -axis tool paths on a 5-axis machine

“…The 5-axis AIM machining results were presented by Gray et al [20] and are used here for comparison purposes. Because each process was not fully optimised for tool dimensions, feed direction, and rapid traverse parameters between tool passes, and since different part geometries, machines, cutting parameters and cutting tools can affect the performance of each method, a complete comprehensive comparison is not possible.…”

“…Similar to the Principal Axis Method [3], the 5-axis AIM, developed by Gray et al [20] is based on the fact that the widest machined strip width is cut when the tool is tilted along the feed direction ( Fig. 1).…”

Integrated method for tool path generation in five-axis sculptured surface machining

“…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.…”

Optimization of 3D laser cutting head orientation based on the minimum energy consumption

“…The two rotations on the table and one additional rotation on the tool axis are determined by the shortest path optimization. Gray et al [6] proposed an AIM method for a 5-axis tool positioning. The AIM is an area-based method that generated gouge-free tool positions without using iterative gouge-check and correction algorithms.…”
