Today, characteristic-based quality analysis has been popular in academia and industry with its ability to show the error evolution of parts during manufacturing. To date, research on characteristics mainly focuses on characteristic sequence, characteristic extraction, characteristic deflection, and characteristic identification, which are all for individual characteristics. However, a key characteristic is not only influenced by each machining itself but also by further machining linked-characteristics. This paper analyzes manufacturing characteristic interactions and presents algorithms, simulation, and experiment for linked characteristic interactions in manufacturing process planning. Firstly, a geometric model shows the tolerance/datum interactions. Secondly, thin-walled parts of aluminum alloy are used to analyze and simulate the machining interactions based on ANSYS system. By analyzing the simulation and experiment results, discussion and evaluation of the results and conclusions are submitted.
