Digital design and manufacture revision notes

Digital Design and Manufacture

Computer Aided Design (CAD)

• Advantages of CAD: CAD allows for precision, easy modifications, and efficient presentation of ideas. It enhances creativity by enabling complex designs that may be difficult to achieve manually.
• Disadvantages of CAD: Initial costs can be high, and there may be a learning curve for users. Additionally, reliance on technology can lead to issues if systems fail.
• Industrial Applications: CAD is used for creating detailed design drawings, utilizing datum points and geometry to ensure accuracy.

Computer Aided Manufacturing (CAM)

• Processes: CAM includes various manufacturing processes such as fabric manufacture, fabric printing, automated cutting, and sewing operations. Each process enhances efficiency and consistency in production.
• Tolerances: Understanding tolerances is essential for ensuring parts fit together correctly in the final product.

Virtual Modelling and Testing

• Importance: Virtual modelling allows designers to simulate and test products before physical production, reducing waste and improving design accuracy.
• Processes: This includes simulation, pattern design systems, and computer-controlled printing for sample fabrics.

Electronic Data Interchange (EDI)

• Usage: EDI facilitates communication between businesses, streamlining processes such as order placement and inventory management.

Production Planning and Control (PPC)

• Role: PPC systems are vital for managing materials, scheduling, and coordinating with suppliers and customers to ensure smooth manufacturing operations.
