14.4 Computer Integrated Manufacturing (CIM)

Computer Integrated Manufacturing (CIM) is a game-changer in modern factories. It uses computers and automation to connect every step of making stuff, from design to shipping. CIM makes everything run smoother, faster, and with fewer mistakes.

This ties into our chapter on automation by showing how computers and robots work together in factories. CIM is like the brain that coordinates all the automated parts, making sure everything works as a team to make better products more efficiently.
