Question 2 of 30

How well do you know G-code?

G-code is the most widely used CNC programming language. G-code is also called preparatory code. This code tells a machine what kind of actions to perform, such as rapid movement, controlled feed movements, switch coordinate systems, set tool information, and more. G-code also communicates what kind of motion is desired. These motions include linear feed, circular fee, rapid positioning, and more.

Discuss with the interviewer your overall knowledge of G-code. Mention where you gained this knowledge and be sure to include how you will apply this knowledge to benefit them, should you be hired.

      Answer Example

      "I am very comfortable with G-code. I first learned G-code while earning my certification in CNC Programming. First, I took the basics, such as programming with G00 & G01 linear movement, G02, and G03 radius generating. Then, I learned FANUC G-Code and how to apply it for mill programming. Overall, I rank my G-code skills as intermediate, and I am eager to expand my knowledge by taking coursework in macro-programming."
