چکیده

This paper describes an algorithm for minimizing the non-productive time or ‘airtime’ for a tool by optimally connecting the toolpaths for that tool. This problem is formulated as a generalized traveling salesman problem with precedence constraints and is solved using a heuristic method. The performance of the heuristic algorithm and the amount of improvement obtained for different problem sizes is also presented. This algorithm has been implemented in our automated process planning system and can be applied easily to other areas of path planning optimization like fused deposition modeling and laser cutting.

Process planning for Floor machining of 2½D pockets based on a morphed spiral tool path pattern

This work proposes a process planning for machining of a Floor which is the most prominent elemental machining feature in a 21⁄2D pocket. Traditionally, the process planning of 21⁄2D pocket machining is posed as stand-alone problem involving either tool selection, tool path generation or machining parameter selection, resulting in sub-optimal plans. For this reason, the tool path generation and...
