Multi-User Collaborative Tool Path Planning Using Process Decomposition

Andrew S. Priddis, W. Edward Red, Brigham Young University

Abstract. Red notes that single-user tools constrain developers in collaborative work environments at every step of the product development process, from idea generation to manufacture. Single-user applications like CAD, CAE, and CAM force a strictly serial design process, which ultimately lengthens time to market. New multi-user applications such as NXConnect address the issue during the design stage of the product development process by enabling users to work in parallel. Could not multi-user collaborative tool path planning software address the same serial limitations in tool path planning, thereby decreasing cost and increasing the quality of manufacturing processes? As part complexity increases, lead times are magnified by serial workflows. Multi-user tool path planning can shorten the process planning time. But, to be effective, it must be possible to intelligently decompose the manufacturing sequence and distribute path planning assignments among several users. Tool path planning is unique in that the processes naturally decompose into distinct activities that can be divided among users. The processes can be defined independently of each other with little regard for what other users have done. There has been some research conducted in decomposition of features in multi-user modeling CAD, but a literature review has not discovered similar research in multi-user tool path planning.
