CNC Jobs - What is the Job of a CNC Machinist? What does a CNC Programming Job Involve?
CNC programmers and CNC operators are responsible for using computer numerically controlled machines in order to cut and shape automobile and machine parts. CNC machinists will use lathes, spindles, milling machines, laser cutting machines, and other machines in order to form a finished manufactured project.
CNC machines will also cut away excess material from a metal or plastic block, in order to form a finished part. CNC programmers will produce large quantities of a single part, frequently called batches. CNC programmer jobs will use their knowledge of computer systems and metals in order to create machine products that will meet demanding specifications.
CNC programmers may also be called numerical tool and process control programmers, and they have the responsibility of writing the CNC programs that operate CNC machines.
A CNC programmer will use computer aided design in order to create a blueprint of a part in then they will determine the actions that the machine will need to make in order to create the finished project. These calculations can include how fast the metal should be fed into the computer numerically controlled machine, where the metal should be removed, and where the CNC machine should cut holes into the metal.
CNC programmers will then taken this blueprint and turn it into a series of instructions, also known as commands, which are typically a series of numbers that would describe the types of cuts, the speed of the cut, and how the cuts should occur. CNC programmers will debug the computer numerically controlled programs in order to make sure that the CNC machine is functioning properly, and CNC operators may run a test to make sure that the machine will not be damaged.
After CNC programming jobs are completed, a CNC setup operator will begin installing or configuring the machine for the job project. Computer controlled machine tool operators will position the machine correctly, download the program, and start the CNC machine. A setup operator has at least minimal programming skills in order to identify any programming errors,. If any problems are detected with the CNC programming, a CNC programmer will modify the program to make sure that it is functioning properly and to improve the computer numerically controlled manufacturing process.
After the work of the CNC setup operator and the CNC programmer are finished, the work will then fall to a CNC machine operator, who will load pieces into the machine and press the start button. If there is a problem with the machine after it has been running for extended period of time, they will call a CNC setup operator to fix any problems.
CNC operator jobs require good hearing in order to listen for specific sounds which can be symptoms of much larger problems, which can damage a CNC machine. These noises can include excessive vibrations and harmonic distortions, and they usually signify that the machine is not properly lubricated or that it should be allowed to rest so that the CNC machine can cool off.
Most CNC machining instruments require very little input from a CNC operator, so one operator can usually work several machines at once.
Working Conditions for CNC Machining Jobs - How is the Working Environment for CNC Operators Jobs?
CNC jobs are usually well lit and ventilated. Machinist jobs can be noisy and present hearing dangers, and CNC tool operators will wear protective equipment and safety glasses in order to protect themselves against flying metal and hearing damage.
CNC control programmers and CNC operators will usually have to work on desktop computers in order to create machine processes, although they may need to go on the floor in order to test a new CNC machine process.
Most CNC programmers, machinists, and operators, will work a 40 hour week, except when new expensive machinery must be installed.
CNC Operator Education - How to Become a CNC Programming - How to Receive Your CNC Machining Training
CNC machine operator education takes a few weeks of on the job training, but CNC setup operators and CNC programmers must have years of experience in order to be able to write programs effectively. Computer programmers and CNC operators will usually enter into technical college programs in order to learn their skills, and computer operators working in shipbuilding or airspace technologies will require an engineering degree.
Courses that a computer control operator and programmer will learn include blueprint reading, computer programming, architectural drafting, computer aided design, and metalworking. Other skills learned can include safety practices, machine processes, and complex physics.
CNC programmers and CNC operator training never ends, as new machines require individuals to update their knowledge of skills, and most machinery employers will offer free training for those who want to advance their skills of machinery processes.
CNC Jobs Training Requirements - How to Become a CNC Machinist
Other qualifications to become a CNC machinist or programmer include a good knowledge of computers and experience with heavy machinery. The National Institute of Metalworking Skills offer certification for those with experience in a metalworking field, and accreditation will expand ones opportunities to enter the field.
CNC machinists can advance to become CNC operators, who themselves may advance to become CNC programmers. Depending on the size of the manufacturing firm, a CNC programmer may become an administrator or open up their own machinist shop.
CNC Operator Employment - What is a CNC Programming Job?
Over the next decade, CNC machine jobs should decline by about 4%, due to advances in CNC machine technology that further automates the process, increasing CNC operator productivity. Increased computer automation of tooling processes is also decreasing employment opportunities for CNC programmers.
While all of these factors may sound like the job prospects for CNC machinists are slim, the opposite is actually true, as very few people decide to enter into the field, and those with training and experience should have no problems finding employment in computer control jobs.
CNC Machining Pay Scale - How Much Do CNC Operators Earn?
In 2006, CNC jobs working in both metal and plastic manufacturing earn $15.23 an hour, with those in metalworking having the highest median wages at $17.45. CNC programmers earned $20.42 on median hour in the same time period.
