Contact A flexible
manufacturing system combines the benefits of highly
automated and controlled systems
- accuracy
- mass production
with the benefits of versatile, adjustable Systems
- flexibilty
- uniqueness of product
A comprhensive describtion of a Flexible Manufacturing System follows here:
A flexible
manufacturing cell (FMC) consists of two or more CNC
machines, a cell computer and a robot.
The cell computer (typically a programmable logic controller) is
interfaced with the microprocessors of the robot and the CNCs.
The functions of the
cell controller include work load balancing, part scheduling, and
material flow control.
The supervision and coordination among the various operations in
a manufacturing cell is also performed by the cell computer.
The software includes features permitting the handling of machine
breakdown, tool breakage and other special situations.
In many applications,
the cell robot also performs tool changing and housekeeping
functions such as chip removal, staging of tools in the tool
changer, and inspection of tools for breakage or expressive wear.
When necessary, the robot can also initiate emergency procedures
such as system shut-down.
Parker-Hannifin Corporation, Forrest City, NC.
The flexible
manufacturing system (FMS) is a configuration of
computer-managed numerical work stations where materials are
automatically handled and machine loaded.
The flexible manufacturing system is principally used in
mid-volume (200 to 30,000 parts per year) mid-variety (5 to 155
part types) production.
Two or more
computer-managed numerical work stations that perform a series of
operations;
An integrated material transport system and a computer that
controls the flow of materials, tools, and information (e.g.
machining data and machine malfunctions) throughout the system;
Auxiliary work stations for loading and unloading, cleaning,
inspection, etc.
- Reduction in
manufacturing cost by lowering direct labor cost and minimizing
scrap, re-work, and material wastage.
- Less skilled labor required.
- Reduction in work-in-process inventory by eliminating the need
for batch processing
- Reduction in production lead time permitting manufacturers to
respond more quickly to the variability of market demand.
- Better process control resulting in consistent quality.
