The model of a computer can be described by four basic units in high-level abstraction which is shown in figure The control of the process remains in the hands of human operators, who may be guided by the information compiled by the computer. The computer is not used to control the operation directly. Computer process monitoring involves a direct computer interface with the manufacturing process for the purpose of observing the process and associated equipment and collecting data from the process. ‘These are the indirect applications in which the computer is used in support of the production operations in the plant, but there is no direct interface between the computer and the manufacturing process.Ĭomputer monitoring and control can be separated into monitoring applications and control applications. These are the direct applications in which the computer is connected directly to the manufacturing process for the purpose of monitoring or controlling the process. As indicated by the definition, the applications of computer-aided manufacturing fall into two broad categories: Examples of these application programs include stress-strain analysis of components, dynamic response of mechanisms, heat transfer calculations, and numerical control part programming.Ĭomputer-aided manufacturing (CAM) can be defined as the use of computer systems to plan, manage, and control the operations of a manufacturing plant through either direct or indirect computer interface with the plant’s production resources.

The computer systems consist of the hardware and software to perform the specialized design functions required by the particular user firm, It is the technology concerned with the use of digital computers to perform certain functions in design and production.Ĭomputer-aided design (CAD) can be defined as the use of computer systems to assist in the creation, modification, analysis, or optimization of a design. CAD/CAM is a term that means computer-aided design and computer-aided manufacturing.
