DELTA COLLEGE COUNSELING/ADVISING & CAREER SERVICES CNC MACHINE PROGRAMMER/OPERATOR Salary Range: $20,600 - $48,760 annually Personal Interests: Mechanical, technical and a scientific interest Work Environment: Primarily indoor, both at desks and in manufacturing plants Description Computer Numeric Controlled (CNC) Machine Tool Programmers/Operators use computer driven machine tools such as lathes, mills, profilers, lasers, water jet, wire electrical discharge machines, tube benders, punches, and grinders to shape metals to precise dimension. Although some programmer/operators can work with a wide variety of CNC machine tools, most specialize in one or two types. Numerical control of machine tools is a form of automated fabrication. Tool programmers write the programs that direct machine tools to perform functions automatically. Programmers must understand how the various machine tools operate and know the working properties of the metals and plastics that are used in the process. functioning properly and that the final product is correct. Numerical Control Tool operators set up and operate single- or multi- purpose numerical control machines to perform machining operations, such as milling, drilling, reaming, or broaching, on metal work pieces according to specifications. Tool operators read blueprints and setup instructions to determine the machining to be done, mount the work piece on an indexing table, and install tools in the tool magazine, turret, or spindle of the machine. They then insert the CNC instructions in the machine control unit (sometimes also write the programs), start the machine checking operation for malfunction, making minor adjustments or tool changes, and then check the work piece to see that it meets specifications. Writing a program for a numerically controlled tool involves several steps. Before tool programmers can begin writing a program, they must analyze the blueprints of whatever function is to be performed or item is to be made. Programmers then determine the steps that must be taken and what tools will be needed. After all necessary computations have been made, the programmers write the program, most often using computer-aided design (CAD) systems. Working Conditions To ensure that a program has been properly designed, tool programmers often perform a test or trial run. Trial runs help ensure that a machine is Programmers usually work in offices of manufacturing plants under the supervision of a senior programmer or coordinator. They may work with a Numeric Control Tool Operators usually work in specialized production departments or tool rooms of factories, tool shops, or job shops under the direction of section leaders, supervisors, or both. Safety rules are established in the plant area; however, operators are exposed to metal chips, abrasive dust, loud noises, sharp cutting tools and revolving parts, where loose-fitting clothing or jewelry is not permitted since it could become tangled in the machines. team of Tool Programmers or alone with complete responsibility for programming. They work in offices that are well lighted and air-conditioned. Generally, Tool Programmers perform their work at desks with occasional trips to the production floor to observe machining operations and test programs. Training, Other Qualifications Sometimes you may find some on-thejob training provided by the employer, although a Certificate, an Associate’s or Bachelor’s Degree will more likely qualify you for this career. Delta College offers an Advanced Certificate in Computer Numerical Control Technology. Tool programming, generally, is not considered an entry-level job; most employers prefer to hire those with experience and technical training. An individual who has completed courses in tool programming, however, may be hired in spite of a lack of experience. Most often though, firms promote skilled machine workers to programming jobs and then pay for their technical training. Other workers enter this field through apprenticeship programs. A growing number of machinists and CNC programmers receive most of their formal training from community or technical colleges. To boost the skill level of machinists and to create a more uniform standard of competency, a number of training facilities and colleges have recently begun implementing curriculums incorporating national skills standards developed by the National Institute of Metalworking Skills (NIMS). After completing such a curriculum and passing a performance requirement and written exam, a NIMS credential is granted to trainees, providing formal recognition of competency in a metalworking field. This designation can lead to advancement or confirmation of skills during a job search. Job Outlook Employment nationally of both computer controlled machine tool operators and numerical tool and process control programmers is expected decline through 2014. In Michigan, growth will be more slowly than average with limited employment opportunities. Earnings Earnings vary widely and depend on job specialty, industry site, and size of employer. Nationally, CNC Machine Tool Programmers had averaged hourly earnings of $9.91 to $22.45 in early 2006. In Michigan they earned from $10.33 to $23.44 per hour.
