Aerospace CAD-CAM Design and Development

Modern computer technology allows the designer to handle the huge number of designs, materials, and process applications under the design of composite material for example. In the past, the designer has to limit the material, process, and design choices to those that were familiar. Now, with the help of a computer, you can develop a series of design concepts, rapidly assess the basic functional and performance criteria established in a wide range of materials and processes, and make any necessary design changes. Finished drawings and specifications may be provided with greater precision and confidence, often in less time than ever before possible. For example, if a size that is changed alters many other dimensions, all sizes will be changed automatically by the computer at the same time the initial changes are made.

It is true that, entering in the first three-dimensional geometry for various concepts in the computer is often more time than the development of sketches with conventional methods. However, subsequent revisions and analyzes of the geometry can be run many times faster than manual methods.

CAD / CAM design and the sharing of database development.

And 'this concept of sharing the database that CAD has made a tremendous time and labor saving tool for the designer. In the past, the evaluation of design concepts to determine their profitability has been a long and tedious. Using a CAD system, initially reported three-dimensional geometry can be refined, modified and manipulated rapidly and preliminary finite element analysis and economic analysis for various materials and processes can be performed. In addition, the database can be copied for CNC tool paths already scaled by the factors shrink to allow a designer to prepare a preliminary draft molds mold.

Design and development models.

Three-dimensional wire frame mockups and models can be constructed to help visualize the product and to serve as a framework for many other modeling programs. These wire frame models are constructed in three dimensions and can be normally displayed in orthographic, axonometric, or perspective, often simultaneously. A change point of view alters all the other points of view. Wire frame can be easily modified, and changes in design can be constructed in a period of relatively short time. This wire frame model, the designer can iteratively merged into one shape into another parameters. Therefore, a wall section or volume of a part can be kept constant, while the shape can change in an incremental manner for a given number of iterations. This process often produces a configuration of potential that has not been possible to find the time-consuming manual methods.

The ability to replace parts of an assembly is of great help in refining and checking some of the operations and functional uses of the product. The parts can be aligned on a common center and modified games and verified from the database. Many hours of cumbersome calculations can be eliminated. The moving parts can be incremental or dynamically rotated about an axis, and interference can be controlled in every position. Color raster technology is further benefit in the verification process. Interferences are more easily when they are each part or position is in a different color .......
