Sample answer
“I have worked with both Haas and Fanuc CNC machines during my training at TAFE Queensland, where I learned to create programs using G-code. I always double-check my measurements using calipers and micrometers to ensure precision. In one instance, I noticed a slight deviation in a part I was machining; I recalibrated the tool and adjusted the feed rate, which solved the issue and ensured the parts met specifications.”
