Currently industrial needs exceed traditional design approach solutions. To satisfy that need designer have to deal with mutually exclusive restrictions. The solution to this problemis to maintain these restrictions with proper methodthat guarantees right result. The concrete casting matrixes are not only transits beauty and art but they have also important technical sense in final product. The master model represents the final product a concrete sidewalk brick which have specified form of the top surface. This special structure of the top surface helps drain water off the brick in order to maintain proper griping properties of it after it rains. As soon as the master model wasscannedit was necessary to change outer border line of 3D model because themaster model appeared to be a little bit bigger than the original one. Finally the 3D model it is the outer border line and its geometry were modified in order to keep the original model functionality. All modifications were done with application of reverse engineering and CAD/CAM software.

In order to meet the needs of enterprises for chamfering complex parts, based on the customization of commercial CAD/CAM software, chamfer programming software is developed. According to user’s machining demands for a part, a chain of edges of a part is extracted from its 3D model. With preprocessing of the chain of edges, the continuity of the chain is estimated, and the start and end point of those edges are automatic obtained. Furthermore, with human-machine dialogue, machining parameters is set by users. By definition of the primary and secondary surfaces of the chain of edges, and interpolation of the edges, the positions of cutter location point and postures of cutter are calculated. Finally the interference of tool path is checked, and tool path is simulated. The software solves the programming problem of chamfering complex parts.

With the help of IGES standard file which was the exchange specification of initial graphics, different CAD system could change the data of product by neutral file’s format conversing. The automatic generation of 3D-Model curve surface in the MCNP input file was realized by using VC++ language.This method has solved the problem of the complication of MCNP geometric modeling process and the 3D-Model input problem in the MCNP. The input of MCNP was transferred the application problem of CAD/CAM software. The data and figure of varies software could be shared and converted. The work of design could be simple, the process of design could be speeded up and the cycle of design was shorted. Work efficiency and practicability were improved. If precision was controlled in 3D-Model, the result could be expected by contrast.

Object customization in Computer Aided Design (CAD) is a method used to modify the sketch parameters and change the model geometries. This method is one of important features in part modelling which empowered CAD user to simply modify their product. The conventional method of modifying CAD model is usually relied on the manual editing. This paper outlines a development of program than can be integrated in CAD/CAM system for real time object customization. It uses Visual Basic (VB) programming with custom Graphical User Interface (GUI) generated in NX10 (CAD/CAM software) interface. The main contribution of this research is a tool for real time object customization that capable to assist the modification of 3D model. In order to develop the tool, 3D model modification instructions are translated into programming codes by using Journaling tools in NX interface. Editable parameters are identified based on the model shapes. The related codes are reconstructed, modified and linked to the functional GUI.  This allows user to simply modify the model shapes in real time with minimum process steps. The performance of the method is evaluated in terms of the reduction of process steps and time in modifying the 3D model in CAD system. All the findings and details of approach are presented.

The exhaust manifold system is mountedon the cylinder head of theengine. It is associated with the catalyst converter at the other end. The emitted gases transmitted from the chamber come out at temperatures of about 800 °C and with pressures extending from 100 to 500 kPa. The exhaust manifold system is exposed to high temperatures and weights which will lead to thermo mechanical failure. Redesigning an exhaust manifold by determining Thermal stresses and deflections exhibited under various operating conditions with different materials and temperatures. The objective is to ensure the suitability of the design for a particular material from the view point of reliability and serviceability.  Defects in existing manifold are cracks usually occur due to prolonged exposure to extreme temperatures, defects in casting and Heat cycling. High end cad cam software such as Unigraphics and Ansys is used for modeling and analysis. The 3d Model of exhaust manifold is subjected to thermal and structural loads and results are tabulated according to the procedure for the Exhaust manifold.

Architectural design is one of those areas that have actively employed interactive design tools such as CAD/CAM software. In order to add a realistic view of the design results in the 3D work process, there have been several recent attempts to employ a virtual reality technology that allows architects to explore design in 3D space. However, VR’s weakness is that common interaction tasks, such as navigation and selection, are still not supported conveniently in 3D space. In addition, VR devices are generally unfamiliar to the average person and are too expensive to use. This paper presents a VR framework that makes the design task easily achieved by employing a PDA interface for a VR interaction applied to street-view emotional color design problems.

With the development of scroll technology, the requirements of more efficient and more accurate processing method for scroll compressor parts become more urgent. This paper proposes a method to improve the machining effect of scroll compressor. The approach is based on 3-point arc approximation method which divides combined profile of scroll wrap into subparagraph arcs that can be interpolated on CNC System. This approach simplifies the programming process and improves the curve fitting effect. The results indicate that the fitting error is in the predetermined range, and the interpolation points of cutter center track are significantly less than those based on CAD/CAM software. The method presented in this paper is of significance to the NC machining of novel precise scroll profile.

The impeller blades are hard to machine for its complex and curved surface structures. It is almost impossible to manufacture the blades by manual programming on Numerical Control Tool. Now, the program almost is completed by the three-dimensional CAD/ CAM software, such as UG, Pro/Engineer, CimatronE which have a lot of machining strategies suitable for a wide variety of parts. However, the result is not perfect if you choose improper strategies. Even more, machining marks will be left on the parts’ surface. This paper takes the impeller for an example and gives the solutions for eliminating machining marks left on the impeller blades’ surface through a comparative analysis on the 3-axis finish machining strategies in CimatronE.
