Abstract: The paper presents the process of building and testing a geometric and kinematic model of a five-axis machining center, which can be used for accurate cutting processes simulation of complex parts. After building the model, it was be tested by simulating the machining process of a hip joint prosthetic device. The prosthetic device was chosen because of its complex shape and because it was obtained by a 3D scanning process, which means that the part was reconstructed using meshes, instead of surfaces, which makes the toolpath control more difficult.

Abstract: Using CAD / CAE / CAM softwaresolidworks obtain material barrels three-dimensional model. The analysis date of dropping simulation, the material barrel filled with heavy objects, free-fall from the height of 1.2 meter on non-normal condition, is got by the function of dropping test and the method of equivalent load setting. The result of analysis is very close to the results of the theoretical calculations. It shows that the design to improve product quality and efficiency has a very important theoretical and practical value.

Abstract: Robots are required to operate in different environmental conditions facing varieties of end-effector to perform the workspace interactions. This paper deals with integrated CAD/CAE/CAM system for SCORBOT-ER Vu plus Industrial robot manipulator. The DH (DenavitHartenberg) coordinate transformation method was used to perform the robot position analysis. The robot manipulator parametric solid models were constructed using Pro/ENGINEER (Pro/E). Pro/Mechanica was used to simulate the dynamic simulation and working space, CATIA was used to implement the cutting simulation, and the prototype was manufactured using a CNC milling machine. Finally, a CAD/CAE/CAM integrated system for a robot manipulator was developed. This integrated system not only promotes automation capabilities for robot manipulator production, but also simplifies the CAD/CAE/CAM process for a robot manipulator.

Abstract: Mold steel 3Cr2Mo has been used widely in manufacturing of plastic mold formed parts, owing to fine mechanical properties. However, it is also very difficult to cut mold formed parts of steel 3Cr2Mo due to high hardness. Ordinary NC cutting method of steel 3Cr2Mo is unable to relate to modern mold manufacturing due to bad cutting property, so it is extremely significant for improving cutting property of steel 3Cr2Mo to study the high speed milling technology. On the basis of improving the traditional cutting force formula, the mathematical model of high speed milling force for steel 3Cr2Mo was derived and solved by using the experimental data and constructing matrix equation based on MATLAB software. Comparing with experimental data, the error of mathematical model of high speed milling force could be controlled within 6 percent. Due to high precision the model of high speed milling force can meet practical engineering requirement and has great value in the fields of CAD/CAM/CAE.

Abstract: This paper takes the parallel indexing cam mechanism as research object and analyzes the formation of the profile of cam. On the basis of Visual C++6.0 object-oriented method, we have successfully developed the CAD/CAE/CAM system of parallel indexing cam mechanisms, which provides the parameter input dialogue frame with friendly interface. We can generate accurate profile data by using it, then create the three-dimensional model of the parallel indexing cam and assemble it with other parts under the Pro/E environment. At last, we don’t build virtual prototype until we transform the model into ADAMS through special interface Mechanism/Pro. Finally, this paper has researched the theory of contact and collision, carries out the motion simulation. We have received many valuable conclusions of practical application through all of the process.

Abstract: Take air conditioner panel for example, it is introduced that the whole process of hot runner injection mold design and manufacture based on CAD/CAE/CAM technology. The panel structure and injection process were analyzed using HuaSu CAE software, then the panel structure was designed using UG/Mold Wizard software, the NC programming and manufacture simulating of the formed parts were done by UG/MACHINE module at last. Compared with the traditional mold design method, CAD/CAE/CAM technology not only can improve the efficiency, shorten production period, but also can reduce the cost of mold design and manufacture greatly.
