Design With 3D CAD Models
Designing products with 3D CAD data has many benefits compared to previous designs in 2D format. Advances in technology, and interfacing the data with other processes allow the following benefits:-
(1) There are many different programs that can be used when designing in 3D. Some of these programs such as solidworks, autocad and pro-engineer are formatted such that they can read and use each others data to create there own files. This is beneficial as the different programs have strengths and weakness with their processing and manipulation of the data.
(2) Design data can be imported into machining centres that enables direct part manufacture so that the designs can be evaluated, or used in full production process. It also allows for tooling cavities to be machined for tooling dies to be used in die casting or plastics moulding.
(3) Design data can also be used to manufacture rapid prototypes or 3D prints. These rapid prototypes can then be used to evaluate the design, by checking clearances in assemblies, the functionality and full movements, and the aesthetics of the design. Once the design has been proven, tooling can then be machined from the data
(4) Significant cost savings can be achieved from evaluating a design in 3D. Once the design has been evaluated and proven, tooling can be machined from the data, which will give the correct sizes post manufacture. With older technology, tooling would require modification to achieve correct sizing, and repeatability of sizing for multiple cavitation could not be guaranteed. This all added cost to the final design of the product.
