Computer Aided Design (CAD) in Design and Product Development (D&PD)
CAD is a process based on the analysis and design of a recreation of the product, with the use of virtual design as a starting point. During the design process of new products, computer aided models are created for different types of prototypes in order to test, evaluate, and validate the conceptual design (Chen, 2009). This process is often iterative and involves several changes to the original design.
For Concept design, Embodiment Design, and Detail Design, CAD is a valuable solution to extract the dimensions of handmade models, clay models and prototypes. For quality control and dimensional inspection, 3D geometry of existing objects can be made to incorporate some of their characteristics in new product design (Jaquero, 2009). In addition, a solution based on 3D scans can also become a powerful tool to preserve the recording and archiving the various iterations of the design.
Question No.2.1
Need the CAD Interface or CAD and Roles in Design and Product Development
Computer Aided Design has been developed to meet a growing demand for designers, mechanical designers, team programmers, technicians and engineers. CAD includes all the software and geometric modelling techniques to design, draw, test, and implement virtual design and product development. The different products constituting CAD cover a wide range of areas, ranging from mechanical design to the design of electrical systems, design or computer aided manufacturing CAD interfaces facilitates design collaboration, encouraging innovation across the extended enterprise (Engell, 2001). It is intended for contractors and their sub-contracting chain, and small and medium enterprises (SMEs). CAD software is widely used in the aerospace sector.
Question No.2.2
AutoCAD interfaces help conceptualization of preliminary structural parts, design parts and assemblies using advanced technologies. It creates, modify, manage and quickly validate the parts, assemblies, and product structure 2d and 3D dimensions. It helps in managing tools for mechanical assembly based on principles of real and tangible structuring. Similarly, Solid works for 2D and 3D carry out various tests by performing calculations of conventional and finite element modelling (Narayan et al., 2008). This helps in product development that stimulates the effective designing process. With Solid works and AutoCAD Civil 3D option, engineers can carry out projects of engineering structures quickly and more accurately (Chen, 2009). Core of Civil 3D is tested in practice dynamic modelling technology that combines the processes of design and creation of working drawings.
Question No.3
Reverse Engineering - Design and Development of a New Product
Reverse engineering (product dissection) is a redesign methodology. Reverse engineering is a systematic methodology to analyze the design of an existing device or system. This means that design is a process that can be applied to an existing product, a prototype or a detailed concept (Leondes, 2001). Reverse engineering is a process that uses a variety of techniques in the form of models, drawings, standards and normative theories to dissect and fully design a product. Product dissection and benchmarking processes are commonly used reverse engineering components in industry to improve product design, produce superior performance and increase product quality ...
