三维实体造型系统中加工特征的识别

FEATURE RECOGNITION IN A 3D SOLID MODEL SYSTEM

本论文是以I-DEAS的GEOMOD造型为识别对象,提出“环一环匹配”和“环一环求交”的法则识别三维零件的加工特征一通孔、盲孔、凹槽、台阶及槽沟等,从而将CAD、CAPP与CAM联成一个统一体。

The feature recognition in this paper is besed on the GEOMOD module of I-DEAS. 'Loop-Loop Matched' (LLM) and 'Loop-Loop Inter-section' (LLI) rules are presented for the recognition of machined features, such as through holes, blind holes, pockets, steps and slots, etc. in attempt to integret CAD, CAPP and CAM.
