CPT Industry 4.0 & Emerging Technologies

Question 1

What does IIoT stand for in the context of Industry 4.0 manufacturing?

Accepted Answer

Industrial Internet of Things

Answer

IIoT stands for Industrial Internet of Things — the network of sensors, devices, and machines on the shop floor that collect and share real-time production data to improve efficiency and decision-making.

Question 2

Which Industry 4.0 technology overlays digital information onto a technician's view of real equipment to assist with maintenance or assembly?

Accepted Answer

Augmented reality (AR)

Answer

Augmented reality (AR) overlays computer-generated information — such as assembly instructions, part labels, or fault indicators — onto the real-world view of machinery, helping technicians work faster and with fewer errors.

Question 3

Additive manufacturing (3D printing) builds parts by:

Accepted Answer

Depositing material layer by layer from a digital model

Answer

Additive manufacturing builds objects by adding material layer by layer based on a digital CAD model, allowing complex geometries that traditional subtractive machining cannot easily produce and reducing material waste.

Question 4

On a smart factory floor, IIoT sensors on machines primarily help production teams by:

Accepted Answer

Collecting real-time operational data to monitor performance and predict failures

Answer

IIoT sensors capture real-time data on temperature, vibration, cycle times, and other parameters, enabling predictive maintenance, faster troubleshooting, and continuous process improvement without requiring manual data collection.

Question 5

In an Industry 4.0 environment, autonomous robots are most commonly deployed to:

Accepted Answer

Perform repetitive, precise, or hazardous tasks that benefit from consistent automation

Answer

Autonomous robots excel at repetitive, high-precision, or hazardous tasks — such as welding, painting, or heavy material handling — improving safety and consistency while freeing human workers for tasks requiring judgment and problem-solving.
