Kim, DS Jun, CS Park, S 2024-01-21T04:37:51Z 2024-01-21T04:37:51Z 2021-09-01 2005-08 0010-4485 https://pubs.kist.re.kr/handle/201004/136277 This paper presents a new efficient and robust tool-path generation method that employs a curve-based approach for clean-up machining. The clean-up machining discussed in this paper is pencil-cut and fillet-cut for a polyhedral model of the STL form with a ball-end mill. The pencil-cut and fillet-cut paths are obtained from the curve-based scanning tool paths on the xz, yz, and xy planes. The scanning tool path has exact sharp-concave points and bi-contact vectors, both of which are very useful to detect 'pencil-points', to trace the pencil-cut path, and to generate the fillet-cut path. In the paper, some illustrative examples are provided, and the characteristics of the proposed method are discussed. (c) 2004 Elsevier Ltd. All rights reserved.
