摘　　要：为了实现机床快速设计目标,研究基于特征约束集的用户自定义特征(UDF)定义方法,利用该唯一性的特征描述方法,构建机床常用特征并组建成UDF特征库,结合Pro/Engineer二次开发软件包Pro/Toolkit,实现了UDF信息准确的提取与重用;开发机床UDF特征库系统,为机床等产品的三维设计提供了快速设计手段,提高了设计效率。In order to design machine tool rapidly,the definition method(UDF) of user defined feature was researched,which was restricted by feature-based constraints. It provided the unique discretional method for features. The commonly UDF library of machine tool was built. Combining with Pro/Engineer secondary development package Pro/Toolkit,the UDF information could be accurate extracted and reused. The UDF feature library system was developed. It provides rapid design tools of three-dimensional design for machine tools and other products,the design efficiency is improved.
