Question 1

In CNC machining, what does the G41 command specify?

Accepted Answer

Cutter radius compensation left

Answer

G41 activates cutter radius compensation to the left of the programmed tool path.

Question 2

Which manufacturing process uses a focused beam of electrons to melt and fuse metal powder layer by layer?

Accepted Answer

Electron Beam Melting (EBM)

Answer

Electron Beam Melting (EBM) uses a high-energy electron beam in a vacuum to fully melt metal powder.

Question 3

What is the primary purpose of a Digital Twin in Computer-Aided Manufacturing?

Accepted Answer

To create a virtual replica for simulation and monitoring of physical assets

Answer

A Digital Twin mirrors a physical asset in real time, enabling simulation, predictive maintenance, and process optimization.

Question 4

In sheet metal forming simulation, which criterion is most commonly used to predict fracture during deep drawing?

Accepted Answer

Forming Limit Diagram (FLD)

Answer

The Forming Limit Diagram (FLD) maps strain states where sheet metal fractures or wrinkles during forming.

Question 5

Which communication protocol is most commonly used for real-time data exchange in industrial IoT (IIoT) manufacturing environments?

Accepted Answer

OPC-UA

Answer

OPC-UA (Open Platform Communications Unified Architecture) is the standard for secure, platform-independent industrial data exchange.
