Abstract: After providing the assembly feature definition and mathematical representation, this paper addresses the problem of how to convert design features into assembly features, with the help of a mathematical model of feature conversion. Assembly feature is defined and represented mathematically using the concept of assembly intents. Some very useful information that can be obtained from the assembly features are mentioned. The mathematical model of feature conversion is represented by a mapping function which is a synthesis function of two process mapping functions. The process of feature mapping is demonstrated with the help of a real-life example.

Keywords: assembly features; feature representation; feature conversion; feature mapping; mathematical modelling; design features.
