Abstract: To solve the problem of expressing process information based on the 3D model is
a hot-point. An expression method for machining process information based on MBD and GB/T
24734-2009 is proposed. This method defines effectively the information sign and the
combination sign, relating the process information and model by 3D annotation. It is showed that
process model and information can be browsed directly. Based on the research, the method has
been validated on the Pro/E platform and an example is presented.

Key words: MBD, process information, 3D annotation
