Abstract: diseussion is given on the exchange of data between arbitrary plaees via computer netwoks as communication medium the use of STEP standard to construct the STEP exchange file,and the design of preand pastproeessors for the exchange of FEM resuIls. At last,an example is given to illustrate the implementation of the exchange of FEM results between different CAD/CAM systems。

Key words: computer aided design, computer aided manufacturing, standards, data, exchanging
