MCQ Questions and Answers on CAD, CAM, and Automation

Q.

The following code will produce dwell for a specified time

A. G18

B. G65

C. G45

D. G04

Answer : Option:- D

Explanation :

The G04 code in CNC programming is used to create a dwell, which is a pause or delay in the machine's operation. This pause allows the machine to remain idle for a set amount of time, ensuring that processes like cooling or settling are completed before moving to the next operation. Dwell time is important in operations that require precise control, such as cutting, drilling, or finishing, to avoid defects or errors caused by premature movement.
