CNC Machinist

CNC machinists work with computer numeric controlled (CNC) heavy machinery from setup to operation to produce parts and tools from metal. CNC machinists make adjustments to the machine to control speed, material feed and path of the cut, as well as make sure the machines are set up properly, working well, and producing quality product. CNC machinists make sure their machines are working at full capacity, are stocked with needed materials, well-maintained and perform periodic checks on output.

Using measuring tools such as micrometers, calipers and depth micrometers the operator will perform detailed inspection of parts and pieces, ensuring the product meets production guidelines. CNC machine operators report quality-control problems such as defects in raw material and finished products, suggesting changes and adjustments to both the raw materials and machine, while maintaining a clean workspace and wash or polish finished products when needed.

Specific duties included but not limited to:

• Figure machine offset positions - through the use of Edge Finders/Mathematical equation
• Sets tooling & Loads in machines
• Downloads program into machines (G-code, Mazak)
• Proves program through 1st piece approval
• Completes inspection data sheet
• Deburrs parts through the use of deburring tools and equipment
• Manual equipment experience to include, but not limited to, drill press, manual milling machines, manual lathes, manual surface grinders

CNC machinists can gain skills through vocational schools, technical colleges or community college programs, or apprenticeships. Typically, it takes 4-5 years of combined education and on-the-job training to become fully trained. To excel, machinists need many years of experience and must show aptitude for math, problem-solving and computer skills.
