  • Design and manufacturing were closely integrated, with the same individuals responsible for both aspects.
• Industrial Revolution (18th-19th Centuries):
  • The advent of machinery and mass production led to the separation of design and manufacturing.
  • Engineers began to focus on designing machines and processes for efficient production.
  • Early pioneers like Henry Ford introduced assembly line techniques, revolutionizing manufacturing.
• 20th Century:
  • The development of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) technologies transformed the field.
  • CAD software enabled engineers to create detailed designs and simulations.
  • CAM systems automated manufacturing processes, improving precision and efficiency.
  • The rise of automation and robotics further enhanced manufacturing capabilities.
• Late 20th and Early 21st Centuries:
  • The integration of digital technologies, such as the Internet of Things (IoT) and cloud computing, has led to the development of smart manufacturing systems.
  • Additive manufacturing (3D printing) has emerged as a disruptive technology, enabling rapid prototyping and customized production.
  • Lean manufacturing and Six Sigma methodologies have become widely adopted to optimize processes and reduce waste.
