Based on the characteristics of gear cutters,the information database for gear cutter design was established on SQL server platform,and a C/S-based integrated information system for gear cutters was developed with Visual C++ 6.

A system diagram that bases on the C/S calculating model is given.

With COM, DCOM, COM+ and ActiveX technology application and development, also very big change happened in the idea that the systematic frame of software draws programming, so we can make good use of the support of C/S model frame that populars in recent years.
