Abstract: There are many problems in the development process of large-scale and complex
CNC system, such as high cost, long period of development and poor efficiency of reusability.
According to the comparability and intercommunity in each system in the domain of CNC, a
development model that oriented domain of CNC is introduced which is based on
component-based software product line method. The architecture of software product line and the architecture of core asset are given, which can enhance efficiency of software reusability, reduce cost, shorten period of development and meet the demand of user’s customization.
