Computer numerically controlled tool operators operate computer-controlled machines or robots to perform machine functions on work pieces. Because of the equipment they work with, CNC operators must have a strong understanding of electronics and computers in addition to materials and manufacturing processes. They may enter computer-generated commands, instructions, and specifications into equipment, install or repair cutting tools or other equipment. When a product has been processed, CNC operators will carefully assess and measure parts to ensure they meet specifications and quality standards.
To become a CNC tool operator requires at least a high school diploma and one to two years of on-the-job training. Some employers require the completion of certifications or apprenticeships. Computer numerically controlled tool operators earn approximately $19.26 an hour.
