The manufacturing industry has changed drastically in the last decade or so. We have gone from manual assembly to cutting-edge robotics and AI faster than we thought. We have witnessed the move from traditional manufacturing, which has mostly involved manual labour and repetitiveness, to smart, intelligent systems that were built at the core to reduce errors and conduct operations in a more efficient way. It is no longer that fascinating idea of automation, but the current state of manufacturing practice.
With such rapid development in technology and increasing competition, companies will use automation more often to have better control of their operations. Whether it is robotics on the factory floor or AI systems for predictive maintenance, it is becoming a base, standard way of operating that is being adopted in the manufacturing industry.
What is Automation in Manufacturing?
Manufacturing automation refers to the use of various technologies to control and monitor production processes with little or no human intervention, including mechanical systems, electrical controls and hardware (its components), software applications, robotics, and artificial intelligence.
Types of Automation:
- Mechanical Automation: This is the use of tools and machines to perform activities like cutting, welding, or assembling.
- Electrical Automation: This includes the use of sensors, PLCs (Programmable Logic Controllers), and control systems.
- Software-Based Automation: This employs software to plan, schedule, and monitor production.
- Robotic Automation: This uses robots for operations that require precision, speed, or safety.
- AI and Machine Learning: These utilize algorithms that allow systems to make decisions based on data and to get better over time.
Historical Background:
Automation in manufacturing has its origins in the Industrial Revolution: the mechanization of equipment. In time, the development of assembly lines (by Henry Ford) and CNC machines in the 1950s opened the door to today’s smart manufacturing systems.
Current Trends in Manufacturing Automation
Integration of Robotics and AI
More and more modern factories are turning to robotics and AI to carry out tasks not previously able to be done. Robots can also operate alongside humans and complete tasks like picking, placing, welding, quality inspection, etc., with more accuracy and speed.
Shift Toward Smart Factories
Smart factories utilize connected devices and systems to build a fully automated, flexible production environment. Integrated data from things such as sensors, machines, and ERP systems, is used to make smart decisions in real-time.
Rise of Industry 4.0
A typical Industry 4.0 concept will involve collaboratively exchanging data and allowing the companies to have independent identities but blueprints with 3 – 4 intertwined manufacturing resources, systems, felt sleeves, resources, and processes completed simultaneously instead of piecemeal processes alone.
