Abstract

According to the characteristics of prismatic parts

a feature-based approach is proposed and applied to reduce the design period of numerical control(NC)programming. The essential idea illustrates that NC programming of prismatic parts can be carried out in the variant method to improve the reusability and manageability of NC codes. Thus

a machining feature model with NC code generated in parameter driven way first should be defined based on the standard operations in specific part manufacturing processes

then a feature library should be created to store and manage the machining features. As a result

NC programming on a complex part can be performed in modular design by combining the codes of several machining features together in reason sequences

and these machining features are extracted from the complex part by using an expert system with manufacturing knowledge library. The prototype has been developed and applied in a heavy cart company in China.
