Computer-aided design and manufacturing (CAD/CAM)

Computer-Aided Design (CAD)

CAD: Stands for Computer-Aided Design, a technology where computer systems are used to aid the greatest parts of the design process.
3D Modelling: Understand how CAD allows for detailed 3D models of products to be created, tested and refined before any physical prototypes are made. CAD can be used to simulate how a product will behave under different conditions.
Design Efficiency: Recognise the ways in which CAD enhances design efficiency by speeding up the design process, allowing for quick alterations to designs, and facilitating easy sharing and collaboration.
Design Accuracy and Consistency: Note that CAD helps in maintaining design consistency by providing precise measurement and specification tools, reducing errors and maintaining consistency across different versions of a design.
Documentation and Record Keeping: Be aware that CAD helps with the creation of comprehensive documentation including geometric specifications, dimensions, material requirements, and assembly instructions, making it an integral tool in the product design process.

CAM: Understand what is meant by Computer-Aided Manufacturing - the use of software and computer-controlled machinery to simplify a manufacturing process.
Interface with CAD: Know that CAM software often interfaces directly with CAD software, allowing for the direct transfer of product designs into manufacturing instructions.
Process Automation: Remember that CAM allows for a high degree of automation, with machinery able to carry out complex processes with minimal human intervention.
Quality and Efficiency: Recognise that CAM can increase efficiency and reduce errors by automating manufacturing processes, leading to higher quality products and reduced wastage.

Rapid Prototyping: Understand the role of CAD/CAM in creating rapid prototypes for testing and evaluation, including methods such as 3D printing.
Scalability: Appreciate the scalability provided by CAD/CAM, with the same design file being used to manufacture individual components, create prototypes, or enable mass production.
Cost and Time Effectiveness: Reflect on how CAD/CAM can help reduce time-to-market and overall product development costs by streamlining the product design and manufacture process.
Standardisation and Customisation: Note that CAD/CAM allows for mass customisation, where standard product designs can be alter subtly to meet individual customer requirements, without the need for a complete redesign.
