Building open CNC systems with software IC chips based on software reuse

Based on the concept of software reuse, this paper discussed the feasibilit y and necessity of developing CNC software IC (SIC) chips and proposes a me thodology for building new CNC systems using multiple SIC chips. A SIC chip is an integrated program to execute certain functions in CNC systems. Diff erent SIC chips can be integrated to build a new CNC system for special sys tem requirements. In this paper, the interactive information among differen t SIC chips is analysed, and related specifications for information exchang e are suggested. In addition, a procedure for developing a SIC chip for NC code interpretation is described and its role in building a CNC system is d iscussed. Lastly, an integrated development platform is presented for build ing an open CNC system with SIC chips.
