In an era where technology and automation dominate the industrial landscape, harnessing their power to create a more efficient manufacturing environment has become a no-brainer. For many businesses today, the Flexible Manufacturing System (FMS) is not just another tech buzzword—it's revolutionizing operations. Dive into this post to appreciate how FMS works, seamlessly blending automation, adaptability, and speed.
It masterfully orchestrates assembly, adapting to the volume requirements and meticulously planning the order of operations to deliver undeniable benefits industry-wide. The future of productivity looks bright—and surprisingly flexible.
A flexible manufacturing system is a sophisticated manufacturing concept that utilizes automated computers to adapt production processes based on changing requirements and variations in product types. The central control computer oversees the operation, directing the transitions between production stages and assembly order.
Production machines play a vital role by receiving instructions from the main control computer and swiftly adjusting tasks as needed. Material handling systems ensure the smooth movement of materials and product components to the production machines.
By employing this integrated approach, flexible manufacturing systems enhance efficiency, reduce costs, and enable industries such as automotive manufacturing and customizable consumer goods to meet diverse market demands effectively.
Understanding Flexible Manufacturing Systems
Over the years, manufacturers have sought ways to increase production efficiency and reduce waste. One of the solutions that came into being was the development of the Flexible Manufacturing System (FMS). FMS is a computer-controlled production system that can efficiently produce small batches of parts, thereby eliminating the need for constant tool changeover.
At its core, FMS seeks to offer an integrated and flexible approach to manufacturing, ensuring that a product is produced with high precision, low lead time, and at a reduced cost.
Imagine an automobile company that produces 10 different car models with varying volume requirements. Under traditional manufacturing systems, different machines would be needed for each type of car. In contrast, an FMS system has a central control system that coordinates all the manufacturing processes required to produce any car type, accounting for variations in their assembly order.
The result is a well-coordinated process that eliminates wastefulness and reduces manufacturing time. This also makes it possible to produce on-demand products that align with consumer preferences.
By 2024, over 85% of manufacturing industry leaders identify flexible manufacturing systems as critical to their operational success strategy.
As per Boston Consulting Group research, in 2023, companies utilizing flexible manufacturing systems reported a productivity increase of up to 30%.
According to a report by IBM, industries leveraging the advantages of flexible manufacturing systems have seen an approximately 20% growth in revenue generation.
Core Components of FMS
Any flexible manufacturing system has three fundamental components: the central control computer, production machines, and material handling systems.
Central Control Computer
The central control computer acts as the brain of the operation in an FMS setup. It ensures seamless communication between production processes by sending orders to other production machines based on pre-programmed algorithms. The computer monitors the entire assembly process, analyzes data collected from sensors in real-time, and adjusts as needed.
Production Machines
Production machines carry out the physical work in FMS systems. They take orders from the central control computer and rapidly change tasks when needed, adapting to the different production requirements. These machines work together in sync, ensuring high-quality products are produced consistently while reducing overall processing time. Examples of these machines include CNC machines (Computer Numerical Control), milling machines, grinders, and lathes.
Material Handling Systems
Material handling systems deliver the raw materials needed for production to the production machines and assist in retrieving produced items. The FMS uses automated material handling systems that operate on tracks or conveyor belts, ensuring a smooth flow of materials through production. These systems ensure that resources are utilized efficiently, with the capability of maximizing production efficiency, keeping a check on the amount of resources used and the number of outputs produced.
Think of an FMS system as a restaurant kitchen, where the chefs (production machines) follow instructions given by the head chef (the central control computer) to prepare each dish (product), and the wait staff (material handling system) deliver ingredients and retrieve the finished product. In addition to this, they also need to have real-time access to the ongoing work to ensure everything runs smoothly.
Now that we have established the core components of FMS, let us focus on how automation plays a crucial role in its success and how adding automated systems enhances its capability.
Role of Automation in FMS
Automation is the backbone of flexible manufacturing systems, enabling industries to react swiftly to changes in demand and reducing costs. A combination of robotic technology and computers helps transition a raw material into an end product. The central control computer operates with sensors to monitor the number of inputs during production. It then uses this feedback data to make decisions automatically, allowing the manufacturing system to operate without human intervention, focusing on the capability to handle a large amount of work effortlessly.
Let's consider an automobile manufacturer producing a specific vehicle type. Several specialized workers would traditionally be responsible for building each vehicle component separately. Each subsystem component (e.g., engine, transmission) would require particular machine tools meant for that process and unique operators experienced in handling them. This process was less efficient since it required coordination between different units and increased inventories, leading to losses in the long run.
However, with automation, everything is combined into one machine - robots build each part simultaneously without changing equipment or stopping between tasks. In essence, by eliminating unnecessary steps, automation not only reduces time and cost but also leads to optimum utilization of resources, handling the large amount of work needed in a shorter time and with greater precision.
Understanding the role of automation, let's take a closer look at how operations flow within a flexible manufacturing system, including the number of processes and how they interact.
Operation of a Flexible Manufacturing System
Flexible manufacturing systems operate on three distinct levels - the part level, machine level, and system level - working together as one seamless whole unit.
At the part level, raw materials enter the line from a storage unit where they are stored until their release by central control's predetermined program. The processing cycle starts immediately after raw materials are released. They are cut into size using end mills or other cutting tools before entering turning machines; after this stage, they are ready for further production at higher levels.
The next level in FMS operation is called the machine level. Here, mechanical arms equipped with robotic technology move around obstruction-free areas, connecting different processing machines as per the central program's demands. The machine level is where drilling, milling, and threading are accomplished.
Finally, the system level brings everything together, where materials processed at the machine level are used for end product creation with a feedback loop to central control for modification based on customer demand or production glitches.
A summary of these 3 levels is presented in the table below:
Level | Process | Equipment Used |
|---|---|---|
Part Level | Raw Material Size Cutting | End Mills and Other Cutting Tools |
- | Turning | Turning Machines |
Machine Level | Material Processing and Machining | Drilling Machines, Milling Machines, Threading Machines |
System Level | Product Creation | Combination of outputs from different machines |
Understanding how flexible manufacturing systems operate, let's delve into how they transition and produce end products, considering the number of steps required and the capability of the system to handle them.
From Setup to Production
Flexible Manufacturing Systems, or FMS technologies, enable the development of a more integrated manufacturing process, making it possible to produce customized products while keeping costs low efficiently. One of the central aspects of the FMS workflow is the setup phase, where specialized machines are pre-programmed to manufacture specific products or components according to unique specifications.
This setup allows operators to have quick access to production variations as required. At this stage, precise cutting and shaping tools and other equipment necessary for production are installed into CNC machines that form part of the overall system. Simultaneously, robotics are employed to optimize machine operations, contributing to the customization of the production process and better inventory management.
Once the machines have been configured, they are set into motion in what's known as the production phase. During this period, sequential tasks are executed continuously without human intervention.
This approach results in minimal human error and reduces product reject rates, saving manufacturers substantial money that would otherwise be lost to failed components or material waste. Here, logistics optimization comes into play as the machines are programmed for maximum efficiency.
Consider an example of a furniture manufacturer looking to customize their designs on demand. The company could utilize FMS technology, bolstered by advanced robotics, to optimize its production process. With an efficient inventory system, they can produce high-quality custom pieces more efficiently in less time than traditional methods.
By integrating all steps under one roof, from conception and design to production lines with computerized controls and flexible machinery, manufacturers can reduce downtime between orders and ultimately improve customer satisfaction.
Role of Technology and Integration
Flexibility has become increasingly essential in modern manufacturing industries, necessitating technological advancements in machine learning capabilities and integrating these systems seamlessly.
Advanced technology such as collaborative robots (cobots) is crucial in automating flexible manufacturing systems by streamlining processes between different production stages, thereby optimizing logistics.
Integrating these systems further to maximize efficiency requires connecting data from various sensors throughout the factory floor through the Internet of Things (IoT). This mechanism enables real-time monitoring of multiple processes across different levels - from materials and inventory management right through to post-production quality control – facilitating faster decision-making based on accurate data.
Technology | Features |
|---|---|
Collaborative robots | Enhances flexibility in the manufacturing process, automate repetitive or hazardous tasks, and promote better accuracy |

Internet of Things | Enables system integration and facilitates faster decision-making based on accurate data |
Machine learning | Learn from previous quality control checks to improve the production process, including inspection systems, production processes, and even scheduling. |
As part of the customization efforts, advanced systems such as Digital Twins can be instrumental in identifying bottlenecks and potential issues before they erupt into a crisis. A digital twin is a virtual replica of physical systems/processes that operators can use to test changes.
Despite these benefits, concerns exist about FMS technology's effect on employment levels. The automation aspect of modern manufacturing, bolstered by robotics and machine learning, reduces labor demand, limiting job opportunities in factories that rely more on manual labor. Employers must understand this shift to develop a long-term workforce strategy that considers inventory management and logistics optimization.
Ultimately, flexible manufacturing systems have numerous benefits for industries across multiple sectors. By executing complex tasks faster and more efficiently than traditional methods while producing high-quality products at high volumes, FMS technologies improve productivity while keeping costs low. Advanced robotics and machine learning aid in optimizing and customizing these processes, taking inventory and logistics into account.
