The acronym CAD stands for PC Helped Design; more importantly, CAD is the center of the new product development process. With CAD, we create all parts and assemblies of a product on the computer. We can use these files to form prototypes, production parts, animations, photographic renderings and run analysis.
To make a part, each details is made as a feature. Each parts starts out as a basic shape and more features are added or removed to make the final part. There are numerous technical requirements that drive the design like wall thickness depending on the type of material,process and need, draft angle needed to remove parts from and injection molding tool, and features that allow parts to fit together correctly.
Assemblies are a collection of parts placed together as they'd be in a product. Then parts can then be viewed in some ways to insure proper fit, to show how parts move and just to grasp the overall look of the entire product. Cross section views can show parts as if they were cut in two. Changing the parts to appear to made from a clear material can help visualise inside workings of products. Files can be saved from the assembly to permit pictures and 3D information to be reviewed by any person.
Prototype and Production Files
At diverse points in the design process, files can be easily made and sent to fabrication sellers for prototypes. Prototypes can range from rough check parts to working assemblies that look just like production parts. Cost of the prototype parts will vary greatly depending on size, material, process and level of finishing. Once the design is complete, all prototypes are tested and proved out and the final design is signed off, files can be made for production parts. There are countless thousands of production sellers in the USA and the world nonetheless , almost every seller can read the common files that may be made with CAD. This process insures the production parts received are will as matching as practicable to the CAD files and prototypes tested.
Animations and Renderings
Creating functional or non-functional prototypes is a critical step in the development process. It allows all members of the design team to see, touch and manipulate the physical model. 3D CAD models on the computer screen are intensely useful for development and are crucial to an effective process, but there is not a replacement for holding actual parts in your hand and working with them in context. There are many forms of prototype like SLA, SLS, Cast Urethane, just to name one or two. We will be able to talk about what with our shopper what options are available as the development moves forward.
Analysis of physical models and prototypes is as vital as evaluation of the ideas. Sometimes totally functional models are created and tested just as production parts would be tested to insure the design will meet the requirements before expensive tooling is initiated. Evaluation will alter for every product primarily based on the prerequisites.
