CNC Machinist / ProgrammerThe CNC Machinist / Programmer is responsible for creating, managing, and optimizing CNC programs using Mastercam for mainly 3-axis milling with occasional 5-axis milling. This role requires an adequate programming background to analyze engineering data and develop tooling strategies that support the broader production team. The CNC Machinist / Programmer sets up and operates milling machines to machine aluminum and trim composite parts, interprets blueprints and engineering specifications, and monitors quality to ensure all work meets customer tolerances and company standards.
Candidates with additional experience programming and operating a gantry-style CMM for dimensional inspection are not required but would be a plus. This role would also be responsible for creating setup documentation when requested by supervisor.Duties & ResponsibilitiesCreate, modify, and store original CNC programs using Mastercam for 3-axis milling machinesAnalyze drawings and design data to determine appropriate tooling, work holding, machine speeds, and feed ratesVerify and simulate CNC programs against CAD models to ensure accuracy prior to runningTroubleshoot and resolve program and process issues, coordinating with supervisor and other functional areas.Plan, design, and produce work holding and job-specific fixtures as requiredAssist operators and machinists with program processes and provide in-process production support when requested by supervisorEnsure parts and tools are loaded correctly and quality is consistently maintained throughout each assignmentChange and adjust cutters as required to meet quality and tolerance requirements; ensure machinery and tools are properly maintainedEnsure accurate documentation is entered on Manufacturing Orders, including correct quantities and specification recordingFocus on continuous improvement through increased throughput and reduced changeover timeStay current with new versions of Mastercam and related programming softwareWhen required, program and operate the company's gantry CMM to perform dimensional inspections and generate inspection reportsProduce setup documentation, tooling documentation, and shop-aided drafting prints to support operators and machinists when requested by managementPerform other duties as assignedSkills & KnowledgeExpert proficiency in Mastercam CAM software for 3-axis programming. Note: 5-axis a plusStrong working knowledge of G-code and CNC machine setup, monitoring, and change-out proceduresAbility to analyze engineering drawings, blueprints, and design data to develop effective machining strategiesProficiency with machine probing for in-process part measurementAbility to apply mathematical functions related to machining, tooling design, and dimensional computationExperience in both production and prototyping environmentsStrong mechanical aptitude and meticulous attention to detailExperience creating setup and tooling documentation to support shop floor operationsCMM programming and operation experience preferred but not required, ideally with gantry-style or large-format equipmentFamiliarity with GD&T and its application to dimensional inspection is a plusProficient in Microsoft Office (Excel, Word, PowerPoint)Effective written and verbal communication skills, with the ability to collaborate across functional teamsMinimum QualificationsAssociate degree in Machining Technology or equivalent relevant work experience (2–3 years)3–5 years of Mastercam experience with 3-axis programming requiredExcellent knowledge of G-code requiredCMM programming and operation experience preferred but not requiredAbility to lift and/or move up to 25 lbs.
