A Flexible production System(FMS) is a manufacturing system in which there is a certain degree of adaptability that permits the mechanism to react in the instance of changes, even if it is predicted or unpredicted. Flexibility is the rate at i m sorry a system deserve to react to and also accommodate change. Come be taken into consideration flexible, the versatility must exist during the whole life bike of a product, from architecture to production to distribution. Flexible manufacturing System is a computer-controlled device that can develop a selection of parts or assets in any kind of order, there is no the time-consuming task of changing machine setups.
You are watching: A basic characteristic of flexible manufacturing is that it
The adaptability being talked about is generally thought about to loss into two categories, which both contain numerous subcategories. The first category, maker Flexibility, consist of the system’s ability to be adjusted to produce brand-new product types, and ability to change the bespeak of operations executed on a part. The second category is referred to as Routing Flexibility, which is composed of the ability to use multiple makers to execute the same procedure on a part, and the system’s ability to absorb large changes, such as in volume, capacity, or capability.
The main benefit of an Flexible manufacturing System is the high adaptability in managing manufacturing resources prefer time and also effort in order to manufacture a brand-new product. The best application of an FMS is uncovered in the manufacturing of small sets of commodities like those native a mass production.
FM solution are claimed to carry out the manufacturer with efficient flexible makers that increase productivity and also produce quality parts. However, FM systems space not the price to all manufacturers’ problems. The level of adaptability is minimal to the technological abilities of the FM systems. FM systems room being used almost everywhere the production world and also though out industries. A simple knowledge that this type of modern technology is an extremely important since FM equipment are involved in virtually everything that you come in call with in today’s world. Native the coffee an equipment to your remote control FM solution are used all over.
History the Flexible manufacturing Systems
At the turn of the twentieth century, Flexible production System did no exist. There was no pressing need for efficiency because the industries were national and also there to be no foreign competition.Manufacturers could tell the consumers what to buy. Throughout that period, Henry Ford had been quoted as saying “People can order any type of color of automobile as long as the is black.” all the power stayed in the hands of the manufacturer and also the consumers hardly had any type of choices.
However, after the second World war a new era in manufacturing was come come. The discovery of brand-new materials and also production techniques boosted quality and also productivity. The war led to the emergence of open foreign markets and brand-new competition.The emphasis of the market shifted from manufacturer come consumer. The first Flexible production System to be patented in 1965 by Theo Williamson that made numerically regulated equipment. Instances of numerically controlled equipment are choose CNC lathes or mills which space varying species of FM systems.
During the 1970s, v the ever-growing developments in the ar of technology, manufacturers started dealing with difficulties and hence, FM systems came to be main-stream in production to accommodate brand-new changes whenever required. Throughout the 1980s for the an initial time manufacturers had actually to take it in factor to consider efficiency, quality, and also flexibility to stay in business.
The procedure of Flexible production Systems
A flexible manufacturing system is an incorporated manufacturing system of computer-controlled maker tools, transportation and handling systems under the regulate of a larger computer. Versatility is attained by having actually an overall system of manage that directs the attributes of both the computer-controlled machine tools and the handling systems. These computer systems space designed to it is in programmed or grouped conveniently with other tools to it is in able to permit fast and also economical changes in production process, permitting quick responses come the market alters and enabling mass customization that products.
As has been discussed over the flexible manufacturing system have the right to be generally classified into two types, relying on the nature of flexibility current in the process, device Flexibility and Routing Flexibility
Flexible manufacturing Systems essentially comprise of three main systems.The processing stations: these are basically automated CNC machines.The automated material handling and also storage system: These affix the work machines to optimize the flow of parts.Central manage computer: This controls the activity of materials and device flow.
The Flexible production System as a system stands out due to the fact that it does no follow a fixed set of process steps. The process sequence changes according to requirement to allow maximum efficiency. Succession of material flow from one device to another is not fixed nor is the sequence of operations in ~ each tool fixed.
Key functions of Flexible production Systems
Some attributes that identify Flexible production System from conventional manufacturing systems room their technological flexibility, i.e., the ability to quickly change mix, routing, and sequence that operations within the components envelope and additionally complexity result from the integration, mechanization, and reprogrammable regulate of to work i.e., parts machining, material handling, and tool change. Some vital features the the procedure are discussed below.
Cell: It consists of number of groupings of two or more automated devices within a company. Each grouping is dubbed a cell. All the machines existing are regulated by a computer. They space programmed to change quickly from one manufacturing run come another. A crucial feature is the automated flow of products to the cell and also the automated removal of the finish item. Numerous cells are connected together by means of an automated materials-handling system, and also the flow of items is controlled by a computer. In this path a computer-integrated manufacturing process is initiated.
Random bypass capability: The material taking care of system has actually a arbitrarily bypass capability, i.e. A component can be moved from any type of tool in the interconnected system to another because the carry system have the right to bypass any kind of tool follow me the path, ~ above demand. This implies:Each part can traverse a variable course through the system.Again, this flexibility in material handling, in combination with multipurpose tools, renders it possible for a flexible manufacturing system to procedure a good diversity the parts.
Automation: computers are the love of automation. They provide the frame for the details systems i m sorry direct activity and screen feedback from an equipment activities. As FMS indicate a wide selection of components, each with their own kind of computer system control, plenty of of these computer system components are mounted as islands of automation, each with a computer system control qualified of monitoring and directing the action. Each of the computer system controls has actually its own communication protocol based on the quantity of data required to regulate the component. Thus, the job of computer system integration is to develop interfaces and also information flow between a wide selection of computer types and models. Computer software provides the ability to transmit timely and also accurate condition information and to utilize details which has actually been connected from other computers in FMS.
Component redundancy: In Flexible production System as the equipment is very integrated, the interruptions of one component impact other components. This outcomes in a higher time to trace the trouble when contrasted with isolated components. In some cases, the interruption could be as result of some other integration effect, and greater downtime may result before the actual cause of the difficulty is found. In this situation, ingredient redundancy provides adaptability with the possibility for choice, i m sorry exists as soon as there space at least two available options. Versatile manufacturing contains functionally indistinguishable machinery. So in case of failure of one device the process flow is directed in the direction of a functionally indistinguishable machine.
Multiple Paths: A route in flexible production represents a component sequence and also requisite fixtures to finish its compelled operations. In a conventional device environment, just one path exists for a component because a single fixture continues to be at a single machine. However, this is no the instance within flexible production systems, wherein there space multiple paths. The number of paths which are current within flexible manufacturing is a measure up of the level of flexibility. Obviously, the higher the number of paths, higher is the degree of flexibility.
Flexibility ranking high in Japan €²s production strategy however not in America €²s. A true flexible manufacturing facility will not only construct different execution of the same car, favor a coupe or a station wagon, top top the same manufacturing line, but additionally a fully different car. This is what the Japanese factory are setting out to do. The expense of one manufacturing facility can it is in spread throughout five or ten cars. Personally from reduced fixed cost, the is additionally less painful to protect against making among those car if it fails to sell.
FMS together a device of manufacturing process can be contrasted to other processes in terms of the product volume that generates and its volume for creating part variations.
The over depicts the place of FMS vis-Ã -vis the of stand-alone machine and transport lines. The horizontal axis represents manufacturing volume level and also the upright axis mirrors the variability the parts. Transport lines are very efficient when producing parts at a big volume in ~ high calculation rate, conversely, stand-alone makers are ideally suited because that variation in rectal configuration and also low production rate. In terms of manufacturing efficiency and also productivity, a space exists in between the high manufacturing rate move machines and the highly flexible machines. FMS, has been related to as a viable solution to leg the gap and also as a gateway to the automated factory of the future.
The Process: Though the functions of this production innovation procedure are comparable across all varieties of firms, the way in which they are embraced and applied depends ~ above product type, manufacturing, maintenance, process planning and quality control processes. That is likewise contingent top top the civilization carrying out these processes; the fertile resources being used and also the organizational arrangements supplied to divide and coordinate the procedures distinguished.
The summary of the layout the a firm that has adopted the flexible production system gives a clean idea of just how the mechanism works in handy life. It has all the functions as mentioned prior to of a common FMS.
Case Study: Toyota’s Lean manufacturing System
Toyota is the most efficient auto agency in the an international industry, many thanks to that is lean production system, developed in an answer to difficulties Toyota’s designers saw with the lengthy production operation of a mass manufacturing system. The problems included the creation of huge and high value inventories, the production of a huge number that defective assets if the initial maker settings to be wrong, and the system’s inability to accommodate diverse customer preferences. Toyota then developed a number of techniques designed come reduce tools setup times–a significant source of fixed costs. This made little production operation economical, which eliminated huge inventories, fewer defective products, and better responsiveness to consumer demands for product diversity. Process innovations allowed Toyota to create a an ext diverse product variety at a lower unit cost than was feasible with traditional mass production.
