This paper describes a novel method for automated process planning from bar stock for rough boring of turned components with monotonic internal geometry. By focussing on a well-defined but substantial part family, we are able to achieve complete automation of all aspects of the process plan, including operations sequencing, parameter selection, NC code generation, etc. Thus, it becomes possible to go from design to NC code in a fully automated fashion. The focus on a tightly defined part family also results in very simple but robust automation algorithms. This is in contrast to much of the reported work on automated process planning, which generally target diverse part families, leading to complex algorithms that fall short of complete design-to-NC automation.
