Component Importance in an FMS
What is a Flexible Manufacturing System (FMS)?
A Flexible Manufacturing System (FMS) is a method of production designed to easily adapt to changes in the type and quantity of the product being manufactured. An FMS consists of three main systems: (1) a set of processing workstations (often CNC machines), (2) an automated material handling and storage system, and (3) a central computer control system. The core purpose is to combine the flexibility of a job shop with the productivity of a transfer line. When people ask, “to calculate FMS which of the following is not used,” they are typically trying to understand the fundamental building blocks of this advanced manufacturing concept. An FMS allows for the automated production of a variety of parts in small-to-medium batches without significant downtime for changeovers.
Common Misconceptions
A primary misconception is that an FMS is completely devoid of human workers. In reality, humans are crucial for management, maintenance, programming, and overseeing the system. The automation applies to the direct processing and transfer of materials. Another misconception is that any automation equals an FMS. An FMS is specifically characterized by its ability to process *different* part styles simultaneously and flexibly, a feature not always present in simpler automated systems. Understanding this is key to figuring out ‘to calculate FMS which of the following is not used’.
FMS Core Components and the ‘Odd One Out’ Logic
Unlike a financial calculation, determining the components of an FMS is a matter of definition. The question ‘to calculate FMS which of the following is not used’ is a logic problem. The “formula” is to identify which element contradicts the core principles of high automation and flexibility. An FMS integrates key automated systems to function.
| Component (Variable) | Meaning | Unit/Type | Typical Range/Example |
|---|---|---|---|
| Processing Workstations | Machines that perform the manufacturing operations. | Hardware | CNC Machining Centers, Assembly Robots |
| Material Handling System | Automated system to move parts between stations. | Hardware/Software | AGVs (Automated Guided Vehicles), Conveyors |
| Central Control Computer | The ‘brain’ that coordinates all machines and transport. | Software/Hardware | Distributed Control System (DCS) |
| Human Operators | Personnel for supervision, maintenance, and control. | People | System Manager, Maintenance Crew |
| Manual-Only Stations | (Distractor) Stations requiring full manual labor without automation integration. | Process Type | Hand-tool assembly benches (not part of FMS core) |
Practical Examples (Real-World Use Cases)
Example 1: Automotive Component Manufacturing
An automotive supplier needs to produce three different types of transmission casings (A, B, and C) on the same line.
- Inputs: An FMS is configured with 5 CNC machining centers, a fleet of 4 AGVs for material transport, and a central computer.
- Process: The computer schedules production. An AGV picks up a raw casting for casing A and delivers it to CNC 1. Simultaneously, another AGV moves a semi-finished part B from CNC 3 to CNC 4 for a different operation.
- Interpretation: The system flexibly produces all three casing types without stopping the line to re-tool. If demand for casing C suddenly increases, the central computer can dynamically re-route parts to maximize output of C. This illustrates how the system works without relying on manual stations, which answers ‘to calculate FMS which of the following is not used’.
Example 2: Aerospace Parts Production
A manufacturer produces low-volume, high-variety aerospace brackets. Each bracket has a unique geometry.
- Inputs: An FMS with multi-axis CNC machines, a robotic arm for tool changing and part handling, and an advanced CAD/CAM-integrated control system.
- Process: The system loads a new CAD file. The robotic arm picks the correct raw material block and secures it in the machine. It then automatically changes tools as needed during the complex milling process.
- Interpretation: This high level of automation and data integration is the essence of an FMS. A manual station would be a bottleneck and is therefore not a core component. The system’s ability to switch between vastly different parts with zero setup time is its key advantage.

Key Factors That Affect FMS Definition
Understanding the factors that define an FMS is critical to deducing which components are essential. The query ‘to calculate FMS which of the following is not used’ is really about these defining principles.
- Level of Automation: The very definition of an FMS relies on a high degree of automation in both processing and material handling. A component that is purely manual contradicts this principle.
- Flexibility: The system must be able to process various part types and change production volumes with minimal effort. This is managed by the central computer, not manual intervention.
- Integration: All components—workstations, handling systems, and computers—must be tightly integrated to work as a single, cohesive unit. Standalone, non-integrated components are not part of an FMS.
- Computer Control: A sophisticated central computer is non-negotiable. It schedules, dispatches, and tracks all activities, making it a cornerstone of the system.
- Routing of Parts: An FMS allows for multiple paths or routes for parts to travel through the system, enabling dynamic response to machine availability or production priority changes.
- Tooling: Automated tool changing and management are often key features, allowing workstations to handle different part requirements without manual setup.
Frequently Asked Questions (FAQ)
-
1. What does FMS stand for?
FMS stands for Flexible Manufacturing System. -
2. Is an FMS the same as an assembly line?
No. A traditional assembly line is typically a ‘fixed’ automation system designed for high-volume production of a single product. An FMS is designed for variety and flexibility in lower-to-medium volumes. -
3. Why is answering ‘to calculate FMS which of the following is not used’ important?
This question tests your fundamental understanding of what defines a modern, automated manufacturing system. It separates core, integrated components from auxiliary or non-essential ones. -
4. Can an FMS have zero human involvement?
No, this is a common myth. An FMS requires skilled personnel for management, programming, loading/unloading raw materials, and performing maintenance. The ‘automation’ refers to the part processing and transfer, not the entire factory operation. -
5. What is the main disadvantage of an FMS?
The primary disadvantage is the high initial investment cost. The complex hardware and software required are expensive to purchase, implement, and maintain. -
6. How does a computer control an FMS?
The central computer manages the master production schedule, dispatches instructions to machines and material handling systems, monitors operational status, and collects data for performance analysis and reporting. -
7. Is a ‘Material Handling System’ always required?
Yes, an *automated* material handling system is a defining characteristic. Without it, you have a collection of standalone machines, not an integrated system. For anyone asking ‘to calculate FMS which of the following is not used’, this is a critical component. -
8. What industries use Flexible Manufacturing Systems?
They are most common in industries with a need for product variety and moderate production volumes, such as automotive, aerospace, heavy equipment, and electronics manufacturing.
