🎯 Role Definition

The CNC Operations Analyst is a hybrid operations-engineering role responsible for optimizing CNC machining processes, developing and validating CNC programs, collaborating with production and quality teams, and driving measurable improvements in efficiency, quality, and cost. This role blends hands-on CNC programming (G-code/CAM), shop-floor troubleshooting, tooling and fixturing strategy, data analysis (SPC/MRP), and cross-functional project leadership to ensure on-time delivery of precision machined components.

Core Responsibilities

Primary Functions

  • Develop, validate, and optimize CNC programs for milling and turning using CAM software (Mastercam, Fusion 360, Siemens NX, HyperMILL), producing clean, efficient G-code for Fanuc, Siemens, Heidenhain and other common controllers.
  • Analyze shop-floor production data (cycle times, setup times, scrap rates, OEE) to identify bottlenecks and implement process improvements that reduce cycle time and cost per part.
  • Lead tooling and fixturing selection, design, and validation to improve workholding stability, reduce rework, and maximize cutter life across multi-op machining sequences.
  • Create and maintain standard operating procedures (SOPs), setup sheets, and work instructions that include tooling lists, offsets, probing routines, and inspection steps to ensure repeatable setups.
  • Program, test, and optimize probing cycles and on-machine inspection sequences (Renishaw, Blum) to minimize first-piece inspection time and automate in-process quality checks.
  • Interpret and apply GD&T, engineering drawings, and BOMs to ensure programmed part features meet tolerance, surface finish, and functional requirements.
  • Conduct first-article inspections and new product introductions (NPIs), collaborating with quality and design engineers to resolve manufacturability issues prior to production ramp.
  • Implement Statistical Process Control (SPC) plans, monitor control charts, and lead corrective actions for out-of-control processes to stabilize production quality.
  • Troubleshoot complex machining issues in real time — chatter, tool wear, poor surface finish, dimensional drift — and execute root cause analysis using 5-Why, fishbone diagrams, and corrective action plans.
  • Optimize tool-path strategies (high-speed machining, trochoidal milling, adaptive clearing) to maximize material removal rates while maintaining part integrity and tool life.
  • Collaborate with maintenance and reliability teams to establish preventive maintenance plans for CNC machines, spindles, and auxiliary equipment to minimize unplanned downtime.
  • Manage tooling inventory and lifecycle tracking including tool presetter data, tool offsets, and regrind schedules to control tooling cost and ensure availability.
  • Deploy lean manufacturing techniques (SMED, 5S, Kaizen events) on the shop floor to reduce changeover time, eliminate waste, and increase throughput.
  • Support ERP/MRP operations by providing accurate routing times, setup data, and labor standards used for capacity planning and scheduling.
  • Maintain and update CAM libraries, tooling databases, and post-processor configurations to ensure consistent program output across multiple machines.
  • Lead cross-functional continuous improvement projects to reduce cost-per-part, increase first-pass yield, and shorten lead times for priority product families.
  • Train and mentor CNC operators and junior programmers on best practices for program loading, offset management, and safe machine operation, improving team capability and consistency.
  • Coordinate with design and R&D teams to provide DFM (Design for Manufacturability) feedback on print tolerances, surface finish requirements, and material choices that impact machining strategy.
  • Execute dimensional verification plans using CMM, calipers, micrometers, and optical comparators and integrate inspection feedback into program revisions.
  • Prepare and present production performance reports, root cause analyses, and continuous improvement results to operations leadership using data visualizations and KPI dashboards.
  • Validate and commission new CNC machines and automation (pallet changers, robot loading) including acceptance testing, capability studies, and baseline process documentation.
  • Ensure compliance with company safety standards, environmental regulations, and ISO/AS quality system requirements as they relate to machining operations and tooling handling.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.
  • Assist procurement with technical specifications and supplier qualification for specialty tooling, cutters, and fixtures.
  • Support continuous improvement of scrap reduction programs and corrective action verification.
  • Help coordinate contract manufacturing or outsourcing decisions by evaluating quoting, lead times, and capability alignment.
  • Provide technical input to cost-reduction initiatives such as material substitution, nesting optimization, and consolidated machining strategies.
