CAM is an acronym for Computer-Aided Manufacturing. Some individuals also refer to CAM as Computer-Aided Machining or Computer-Aided Modeling. CAM refers to the use of software to control machine tools. For this reason, CAM is used in CNC operations.
There are several versions of CAM software that you may know, depending on your level of experience with CAM and the focus of your work. Some popular CAM software options may include:
- EDGECAM
- HSMWorks
- LinuxCNC
- Aspire
The interviewer would like for you to discuss the software that you know, and your level of comfortability with each program that you mention. You could specify how much time you have invested in learning your leading CAM software or even talk about your experience training others on these programs.

"I am well versed in a variety of CAM programming and software including Mastercam, GibbsCAM and Siemens PLM Software. My strongest experience is with Mastercam, specifically with their mill and lathe solutions, from my experience at Company ABC. There, I used Mastercam for eight years. My secondary experience would be in GibbsCAM, as I worked with this software for around three years at Shop XYZ. I would rank my experience level in GibbsCAM as intermediate."
