CNC machinists are responsible for creating some of the most important manufactured parts on the planet. Computer numerical control (CNC) machines turn and shape materials like metal, plastic and wood into intricate parts and complete products. Components created using CNC machines are found in medical equipment, cell phones, computers and many other products that people use every day.
During and after a CNC machine creates a part or product, a quality control inspector ensures the piece adheres to specifications. This is an important job because the quality control inspector is responsible for the final product. A faulty part or component could render an entire product useless or unsafe.
Learn more about what a quality control inspector does, how to become one, and what the job outlook is like for quality control inspectors.
Quality control inspectors check finished products made with CNC machines. They also inspect CNC machines and parts as they’re being made and before they’re ready for finishing. Sometimes quality control inspectors work during the process to save time and ensure the part comes out correctly, especially when a parts program is still being developed. Once whatever the CNC machine produces is finished, the inspector will once again check the part.
The quality control inspection process typically includes the following steps:
A qualify control inspector makes sure parts and products adhere to the established standards of measurements, quality, strength and endurance. If not, they can become a costly and dangerous problem.
Completing a formal training program like the CNC Machining Technology program offered at NASCAR Technical Institute can give you a great foundation of skills to build on if you’re looking to become a quality control inspector.1 During the 36-week program, you can learn how to operate CNC machines and ensure parts are created to correct specifications.
CNC machine quality control inspectors need to have experience using computers to work with computer-aided manufacturing (CAM) technology and need to know how to use CNC machine tools and computerized measuring machines.
CNC quality control inspectors must have physical strength and stamina, since they’re on their feet working with machinery. They also need to have technical skills, mechanical skills, math skills and dexterity to ensure products are completed successfully.
Certifications are not typically required for quality control inspector positions, but formal training like UTI’s CNC Machining Technology program and certifications can help make candidates stand out. The American Society for Quality offers a Certified Quality Inspector designation, plus various Six Sigma certifications that can provide value to employers. There are also industry-specific programs like the Skills Certification System from The Manufacturing Institute that are available to help train quality control inspectors.
Many quality control inspectors began their careers in CNC machining. According to the Bureau of Labor Statistics (BLS), the median annual salary for computer numerically controlled tool operators in the United States was $46,760 in May 2022.34 This means half of CNC machinists earned more and half earned less. Keep in mind that salary depends on several factors, including experience, employer, demand and cost of living in the area.
Settings in which quality control inspectors can work include:
Wherever parts and goods are manufactured, quality control inspection must take place before they are sold or distributed.
CNC quality control inspectors have very important roles in ensuring parts and products are fit to specifications. These are parts that are in machines people use for transportation, in equipment that powers hospitals and life-saving products, and in devices people rely on for work and communication. Quality control inspectors can play a major role in the production of essential items.
