CNC Operators work hard to manufacture the machined parts that we use in our every day lives. Some of these parts are straightforward, and others are highly complex. Talk to the interviewer about the parts that you are accustomed to creating. Perhaps you received digital blueprints for a highly complex part that required a great deal of blueprint interpretation and calculations using trigonometry. What have you found to be the most challenging task in your machining career so far?

"The toughest parts that I have created were surrounding aerospace components for the military when I worked as a CNC Operator for Company ABC. In that role, I faced added pressure for perfection, considering the nature of the parts. The parts we created were are much more complicated than one would think - not only because of the plans and precision but because of the materials we used, such as titanium and Kovar. In this role, I created parts such as miniature gears and sonic nozzles with precision venturis for flow measurement. These parts required skills in various micromachining techniques. Because of this experience, I feel well prepared to machine a multitude of complex parts."
