AGILE MANUFACTURING
INTRODUCTION
The idea of Agile Manufacturing (AM) now had been around for nearly a decade. AM is the first major manufacturing theory that has sense of history built into it, in fact integral to it.
Agility is the measure of manufacturer’s ability to react to sudden unpredictable change in customer demand for its products and services and make a profit.
Agile Manufacturing may be defined as “The ability of an organization to thrive in the competitive environment of continuous and unanticipated change and to respond quickly to rapid change in markets driven by customer based valuing of products and services.”
CHARACTERISTICS OF AGILE MANUFACTURING
Manufacturing companies that are agile competitors tend to exhibit these principles or characteristics .The four principles are:
Organize to Master Change
Leverage the Impact of People and Information
Enrich the Customer
Cooperate to Enhance Competitiveness
AGILITY CAPABILITY INDICATOR
This shows the key factors of an organization and the relationship between these factors.
It is intended that this model should not slavishly follow functional divisions, or processes, but encapsulate the idea of generic organizational relationships.
AGILE WOKCELL
In agile manufacturing rapid changeover is accomplished through the use of reusable software, quick-change grippers for the robotic manipulators, modular worktables, and part feeders.
These are flexible enough to handle several types of parts without needing mechanical adjustment.
These feeders use vision, in place of hard fixturing, to determine the position and orientation of parts.
AGILE WOKCELL
Design strategies for agile manufacturing
Vision-based flexible parts-feeder systems.
The introduction of “spurs” within the conveyor system.
The use of modular worktables supporting specialty fixturing and tooling.
Multipurpose, modular end-of-arm tooling.
Flexible Parts Feeders
Flexibility encompasses every part of the work cell design, including hardware and control software.
Our flexible feeders consist of three conveyors working in concert.
Spurs and Worktables
It has introduced the concept of “spurs” and modular worktables for flexibility and efficient use of space.
A recent improvement in the modular is the introduction of quick-connect pneumatic and electrical harnesses
Agile Grippers
The gripper design is an important aspect of achieving efficient and reliable robotic part handling.
Figure shows a part being lifted from the feeder and being rotated into an orientation needed for assembly.
DESIGN FOR AGILE MANUFACTURABILITY
Agile work cell should be capable of designing new products.
Design for manufacturability teaches that the interaction of the components in a product is critical to a successful automated assembly.
A few, often simple, changes to a product in the early stages of design can have a marked impact during final production.
SOFTWARE ARCHITECTURE FOR AGILE MANUFACTURING
Comparison of Dedicated, Agile, Flexible manufacturing
APPLICATIONS
Several companies have implemented what may be considered “agile” manufacturing.
Motorola has developed an automated factory with the ability to produce physically different pagers on the same production line.
At Panasonic, a combination of flexible manufacturing and just-in-time processing is being used to manufacture bicycles from combinations of a group of core parts.
Advantages:
Lowers Manufacturing cost
Increase market share
Facilitate introduction of new products
Eliminate non-value added activities
Increase Manufacturing Competitiveness.
Conclusion
Product design for manufacturing and assembly play a key roll in facilitating feeding and assembly.
Agile parts feeding can be addressed with flexible part feeders exploiting machine vision.
The modular worktable and conveyor spurs are important concepts for optimizing use of valuable robot workspace as well as supporting rapid change over to new assembly tasks.
Agile Manufacturing does not contribute any of other manufacturing concepts So that elements and extensions of best practices documented in them may be incorporated to support Agile Manufacturing as long as they are integrated to achieve agility collectively.
