Overview of Computer-Aided Manufacture (CAM)

Computer-Aided Manufacture (CAM) refers to the use of software and computer-controlled machinery to simplify manufacturing processes.
The key purpose of CAM is to create a faster production process and components and increase the quality of the final product.
CAM works in conjunction with CAD software where the output of CAD software becomes the input for CAM software.

CAM Software

Different CAM software packages are available, each with its unique set of functionalities, such as CNC programming, toolpath generation, and machine simulation.
CAM systems utilize algorithms for toolpath calculation to ensure efficient and effective part machining.
Key software in this domain includes Mastercam, GibbsCAM, and SolidCAM.

CAM offers the potential for enhanced manufacturing precision as all actions are purely computer-based and thus less error-prone.
It provides an opportunity for mass production as the same detailed instructions can be precisely replicated.
CAM can significantly reduce waste as it optimises the use of raw materials.
It facilitates a smooth transition from design to production via the integration of CAD/CAM systems.

There is a large initial cost to install the necessary machinery and software.
CAM requires skilled operators and programmers, necessitating potentially expensive training and retraining.
Its use could potentially cause a reduction in employment, as computerised systems replace manual jobs.
The reliability of the production depends on the constant availability of the computer systems.

CAM promotes the concept of ‘lights out’ manufacturing, enabling a round-the-clock production capability with minimal human intervention.
The integration of CAM systems with CAD systems is increasingly enabling a direct CAD to product manufacturing process, improving production efficiency.
It facilitates flexible manufacturing systems, allowing for a high mix of different products to be produced with the same machinery.
CAM has caused a significant shift towards automation in manufacturing industries, with implications on the workforce and productivity.
