 Abstract In this paper, 3D modeling and motion simulation of the typical products and CAI courseware are made for machinery manufacturing professional comprehensive training. Today computer-aided design, checking and system motion simulation has gradually become the direction of the mechanical design. The assembly and disassembly of the product also are difficult. How to guide students to correct assembly and disassembly and ensure recycled use of product has become the focus of laboratory personnel. CAI courseware will effectively solve the problem.

The following work is done including disassembly, mapping, engineering drawings, 3D modeling, process development, NC machining simulation processing and so on, through analysis of the work principle and internal structure based on the construction and the related technical parameters. We concentrate on the 3D Modeling and visual assembly of component based on Solidworks to present the movement of products more vivid and concrete. We machine the engine frame and use Mastercam to program the box component automaticly, and NC machining process system simulation by Vericut. We make the exploring view, 3D animation and motion simulation video by VideoStudio to compile the words and soundtrack. Then, we integrate those video into CAI courseware to show the dismounting procedure and movement in order to guide the operator the dismounting of product.
