Core Responsibilities

Primary Functions

  • Conduct comprehensive on-site process and machine tool audits to evaluate CNC machine utilization, setup practices, tool life, fixturing, and flow; document findings and deliver prioritized improvement roadmaps with ROI estimates.
  • Develop, optimize, and validate CNC programs (G-code) and CAM toolpaths for milling, turning, mill-turn, and multi-axis applications using Mastercam, Fusion 360, GibbsCAM or equivalent to reduce cycle times and improve surface finish and accuracy.
  • Design and recommend fixtures, workholding strategies, and tooling setups that minimize part handling, reduce setup time, and maintain tolerance control for high-volume and prototype production runs.
  • Analyze cutting parameters (speeds, feeds, DOC), tool engagement, and spindle utilization; deliver tooling and cutting parameter recommendations to extend tool life and reduce scrap and rework.
  • Implement standard operating procedures (SOPs), machining instructions, setup sheets, and first-article inspection plans that embed GD&T callouts, process limits, and measurement steps to ensure repeatable manufacturing quality.
  • Lead machine commissioning and retrofit projects, including mechanical alignment, controller parameter setup (Fanuc/Siemens/Heidenhain), axis tuning, backlash compensation, and post-upgrade validation.
  • Troubleshoot complex machine and process problems — mechanical, control, and program-related — using root-cause analysis and structured problem-solving methodologies to restore production and prevent recurrence.
  • Integrate CNC centers with automation solutions (robotic loading/unloading, pallet changers, conveyors) to increase uptime and reduce manual handling; produce supplier specifications and oversee vendor installation and acceptance testing.
  • Perform part cost modeling and cycle-time analysis to support quoting, pricing strategies, and make-vs-buy decisions, delivering data-driven recommendations that improve margins.
  • Train and mentor shop personnel — machinists, NC programmers, and process engineers — with tailored curricula on G-code best practices, CAM workflow, spindle/tooling management, and quality inspection methods.
  • Validate and migrate legacy CNC programs into modern CAM-managed workflows; standardize program structure, comments, and revision control to support maintainability and knowledge transfer.
  • Lead continuous improvement initiatives (5S, Kaizen, DMAIC) targeted at machining operations to reduce lead times, eliminate bottlenecks, and increase overall equipment effectiveness (OEE).
  • Implement and interpret SPC (statistical process control) charts, capability studies (Cpk), and tolerance analyses to convert production variability into actionable countermeasures.
  • Advise on materials selection and machinability considerations (aluminum, stainless, titanium, Inconel, high-performance plastics) and recommend tooling/coating strategies to balance cost, cycle time, and quality.
  • Coordinate cross-functional teams for new product introduction (NPI) and transfer of production between sites, ensuring design for manufacturability (DFM/DFMA) principles are applied and process validation is complete.
  • Support supplier and vendor selection for tooling, fixtures, and machine hardware; draft technical RFQs and evaluate vendor capabilities and quotations against technical and commercial criteria.
  • Prepare and present technical proposals, project plans, and status reports to stakeholders and clients, including milestones, risk registers, resource plans, and post-implementation performance metrics.
  • Ensure machining processes and facilities comply with safety, environmental, and quality standards including ISO 9001 and customer-specific quality systems; maintain documentation for audits and certifications.
  • Conduct non-destructive testing (NDT) and coordinate metrology activities using CMM, optical comparators, and handheld inspection tools to verify critical dimensions and support quality claims.
  • Implement and maintain preventive maintenance programs for CNC centers, spindles, and auxiliary equipment to reduce unplanned downtime and extend asset life.
  • Evaluate and recommend ERP/MRP and MES integration points for CNC operations to improve production scheduling, traceability, and scrap/waste tracking.
  • Estimate and deliver cost-saving initiatives through tooling consolidation, scrap reduction, energy efficiencies, and optimized toolpaths; quantify savings and track KPI improvements post-implementation.
  • Provide remote and on-site technical support during critical production ramps, including urgent program updates, toolpath fixes, fixturing adjustments, and corrective action plans.

Secondary Functions

  • Develop training materials and e-learning modules documenting CNC best practices and shop standards to accelerate operator competency growth.
  • Collaborate with R&D and design engineering teams to incorporate machining constraints early in product design, reducing redesign cycles and tooling costs.
  • Support sales and pre-sales teams with technical input for proposals, demonstrations, and proof-of-concept machining runs.
  • Maintain a library of machining case studies and benchmark data to support future consulting engagements and internal knowledge reuse.
  • Monitor industry trends in cutting tool technology, CAM capabilities, additive-hybrid manufacturing, and digital twinning to propose pilot projects and strategic investments.
  • Assist in procurement reviews to ensure tooling and machine purchases align with long-term process capability and business objectives.
  • Facilitate supplier quality agreements and first article inspections for outsourced machining or critical purchased components.
