CNC Machinist; 3rd Shift

SUMMARY

The Machinist sets up and operates CNC and conventional machining equipment to mill, drill, bore, ream, and finish parts produced from extrusions, bar stock, forgings, plate, and assemblies. This position interprets technical documentation, controls CNC programs at the machine, uses precision measuring equipment to verify conformance, and supports safe, efficient production of parts that meet or exceed customer specifications.

• Set up and operate 3-, 4-, and 5-axis CNC machines and conventional equipment using a variety of machine controls
• Mill, drill, bore, ream, and finish parts manufactured from extrusions, bar stock, forgings, plate, and assemblies
• Read and follow blueprints, mylars, engineering orders, statistical process controls, planning change requests, planning documents, setup sheets, work instructions, shop charts, and verbal instructions
• Control CNC programs at the machine in accordance with established procedures and protocols
• Select, install, and verify cutters, tools, tool holders, fixtures, offsets, and related setup components
• Use precision measuring equipment to inspect work throughout the production process and verify customer requirements
• Ensure company-owned precision measuring equipment is within its required calibration period
• Maintain quality standards, identify workmanship issues, troubleshoot quality problems, and reduce scrap and defects
• Perform preventive maintenance according to the checklist located at the machine
• Use forklifts, hoists, overhead cranes, and deburring tools such as orbital sanders, angle grinders, cut-off wheels, and burr knives as trained and authorized
• Maintain machine tie-in and production records; document problems and communicate them to the lead, next operator, supervisor, engineering, or programming personnel
• Complete Planning Change Requests, program prove-out sheets, root-cause and corrective-action documents, DRATS, and other required production records as applicable to assigned level
• Coordinate with tooling, quality, engineering, scheduling, programming, and other departments to maintain production flow
• Evaluate setup and run processes to reduce internal setup time, improve productivity, and enhance quality with supervisor or lead approval
