Computer-Control Machine Tool Operator
A Computer-Control Machine Tool Operator is a skilled professional responsible for setting up and operating computer numerical controlled (CNC) machines, which are essential for shaping and cutting metal and plastic materials in various manufacturing industries. This role typically requires a high school diploma, and while formal postsecondary education is not mandatory, completing certification programs in technical schools or community colleges can enhance job prospects. Operators work with different types of CNC machines, such as lathes and mills, and are tasked with monitoring machine operations, making adjustments, and ensuring safety and quality standards are upheld.
The work environment is often found in machine shops, where operators must adhere to strict safety protocols due to potential hazards, including noise and exposure to contaminants. Individuals in this profession tend to have a strong interest in machinery and mechanical problem-solving and must possess a keen attention to detail for precision tasks. On-the-job training is common, allowing operators to gain the necessary skills to perform their responsibilities effectively. The job outlook for this occupation indicates a slight decline in demand, reinforcing the importance of continuous skill development and adaptability. Overall, Computer-Control Machine Tool Operators play a critical role in the manufacturing sector, contributing to the production of a wide range of products.

Overview
Sphere of Work. Computer-control machine tool operators are responsible for the setup and operation of computer numerical controlled (CNC) machines, including lathes, mills, and turning machines. They operate machines that form, shape, and cut metal and plastic materials used in factories. Operators are responsible for monitoring machines and adjusting them as needed. Computer-controlled machine tool operators work in a wide range of industries, from automotive manufacturing to machinery and plastics production.
Work Environment. Computer control machine tool operators work in machine shops. As these shops present a number of safety hazards, operators must wear earplugs for protection from work noise, safety goggles to protect eyes from flying particles, and reinforced boots to protect feet from heavy equipment. Operators are expected to adhere to strict quality control and safety standards. Most computer-control machine tool operators stand throughout the day, but movement is limited and repetitive.
Occupation Interest. Individuals drawn to the profession tend to be independent workers who are interested in complex machinery. They should be able to perform routine tasks without losing attention to detail. Operators are invested in accuracy and precision and interested in mechanical problem-solving. Although they work independently, operators must cooperate regularly with colleagues. Individuals interested in the computer-control machine field must be knowledgeable about computer programming, design templates, and computer software. They must work well under pressure and be able to remain focused for long periods.
A Day in the Life—Duties and Responsibilities. The daily duties of a computer control machine tool operator include inspecting machines for wear and damage before beginning machine operation. Once a machine is in operation, the operator calculates how best to lift and feed materials through the machine and monitors the size and shape of cuts. Some operators may use cranes or lifts to maneuver large pieces. Operators listen for sounds that may indicate worn or faulty components and check for changes in machine vibration and temperature that might indicate a problem. Lubricants and cooling systems are employed to ensure proper machine operation. On occasion, an operator may stop a machine to make minor repairs or to modify or adjust processing according to preset machining sequences.
Computer control machine tool operators use precision tools to install, align, or replace bits and cutting heads. They prepare materials for processing while the machine is in operation, ensuring smooth workflow. They also inspect and measure finished pieces with gauges and calipers to ensure correct machine operation and may work with production lines that include hoists and conveyor belts. Operators are also responsible for cleaning their machines and performing closing inspections at the end of the workday.
Operators are not often required to write, but they must be able to follow complex written instructions. They are often responsible for the input of production data and sometimes the creation of reports. Computer-control machine tool operators may confer with programmers and supervisors to identify problems with machining programs.
Numerical Control Milling-Machine Operators (605.380-010). Numerical Control Milling-Machine Operators set up and operate multi-axis, numerically controlled milling machines to mill surfaces on metallic and non-metallic workpieces.
Numerical Control Drill-Press Operators (606.362-010). Numerical Control Drill-Press Operators set up and operate numerically controlled drill presses that automatically perform machining operations such as drilling, reaming, counter-sinking, spot-facing and tapping of holes in metal workpieces.
Numerical Control Jig-Boring Machine Operators (606.382-014). Numerical Control Jig-Boring Machine Operators set up and operate numerically controlled jig-boring machines to perform such jigging operations as boring, drilling and counter-sinking holes in metal workpieces.
Work Environment
Immediate Physical Environment. Most computer-control machine tool operators work in machine shops contained within larger factories. Some operators work with very large pieces of material, such as aerospace components, and must use hoists, cranes, and other lifting devices. Machine shops may be noisy and may contain contaminants such as particulates and hazardous fumes; operators must wear protective gear such as clothing and masks to reduce exposure.
Human Environment. Although computer-control machine tool operators carry out their daily tasks independently, they usually work in a team setting, so physical proximity to other workers is common. Noise and vibration make routine communication difficult. Periodic contact may be made with others to ask for advice or receive instructions.
Technological Environment. Computer-control machine tool operators must have some knowledge of computer-aided design (CAD) programs, as they may be required to perform basic programming functions. They sometimes use industrial control software that monitors workflow and inventory and enter data into spreadsheets for reporting purposes.
Education, Training, and Advancement
High School/Secondary. Students interested in the field of computer-control machine tool operation should study mathematics and mechanics and take any available classes in basic engineering, design, and drafting. Courses in shop math and geometry are also beneficial to those interested in the field.
Postsecondary. Although postsecondary education is typically not required, aspiring computer control machine tool operators may benefit from certified training programs available at many community colleges and technical and vocational schools. Training for the field is also available in the military. Professional organizations such as the National Institute for Metalworking Skills (NIMS) provide resources for those interested in pursuing certified training, including lists of accredited programs. Courses in CAD programs and industrial design may also be helpful.
