CONTROL SYSTEM

Computers have revolutionized manufacturing. They have given manufacturing engineers control over events in the factory. With this information, processes can be reorganized for maximum efficiency and production steps can be rearranged for maximum cost savings. You can know what is occurring on the floor now.

Because of computers tasks are done more quickly and accurately. It enables engineers to make changes or corrections that will utilize equipment and people optimally.

An important quality of computers is that they are flexible. Change the program and you have a "new computer".

Software. Computers cannot run without software; that is, without some instructions on what to do. Software controls the flow of information in a computer system. The software makes a computer la specific device — a calculator, a designer, a program­mer, a cost estimator, an expert.

Simulation software is another type of software which is now becoming quite popular. This type of software lets you see your proposed factory layout at work "on paper".

Simulation software helps in the design and development of automated work cells, manufacturing systems and factories such as FMS.

An FMS without software is not flexible, has little use in manufacturing and is not even a system.

The main problems that FMS software should solve are as follows:

Keep track1 of the materials being manufactured, determine the exact physical location in the system and perform the correct sequence of operations.

Prevent the different operations from interfering with2 each other.

Determine error conditions and minimize their impact on the system.

Keep management informed on parts, production, part programming, system status.

Determine the best production schedule to meet due data and maximize machine utilization.

Forecast system needs at due time — fixtures, tools, lubricants and coolants.

Direct in real-time the operations of people in charge of3 the above facilities. Compare actual and forecast performances.

Inform the plant management with the required data from FMS, for production planning and control, accounting and reporting.

Thus, the FMS control system manages the total combination of devices in the system that contributes to the automatic operation of the production process. This includes the machine-tool controllers, the material handling system, the system monitoring devices, the system communications, and finally the system computer. Computer software supplies all the control management and monitoring functions that enable the system to achieve high utilization.

The control system is easily visualized4 by considering all the elements of the system in a structured arrangement according to its function. This structure and how each function of the structure relates to the overall system performance will be discussed later.
