Core Responsibilities

Primary Functions

Lead, schedule and prioritize daily CNC production activities for assigned cells or shifts to meet on-time delivery and customer requirements while maintaining compliance with safety and quality standards.
Supervise, coach and mentor a team of CNC operators and setup technicians, conducting regular performance feedback, training in G-code/CAM, and skills development to build a high-performing machining team.
Program and optimize CNC toolpaths using CAM systems (e.g., Mastercam, Fusion 360, GibbsCAM) and validate programs via simulation to reduce cycle time and eliminate collisions or rework.
Perform complex machine setups and first-article setups for new parts, including fixture design, workholding selection, tool selection, offsets, and trial cuts to ensure right-first-time production.
Generate, review and maintain CNC programs (G-code) for 3-axis through 5-axis mills and multi-axis lathes, and update programs to incorporate engineering changes, tooling improvements, or process optimizations.
Analyze and optimize feeds, speeds, and cutting strategies to extend tool life, improve surface finish, and increase machining throughput while maintaining dimensional tolerance.
Collaborate with engineering and tooling vendors to qualify new tooling, cutting inserts, and fixture concepts; negotiate tooling specs and validate performance in production conditions.
Drive continuous improvement projects (Kaizen, 5S, SMED, Value Stream Mapping) to reduce setup times, scrap, and non-value-added activities, tracking cost savings and productivity gains.
Interpret engineering drawings and prints using GD&T principles to ensure parts are produced to specification; partner with quality to resolve tolerance and inspection issues.
Oversee in-process inspection and final inspection activities, operate and program CMMs, and ensure measurement traceability and documentation for first articles and production lots.
Troubleshoot complex machining problems—vibration, chatter, tool breakage, and tolerance drift—performing root cause analysis and implementing corrective actions that prevent recurrence.
Maintain production reports, SPC charts and key performance indicators (OEE, yield, cycle time) to inform management decisions and identify areas for improvement.
Ensure machine preventative maintenance schedules are followed, coordinate repair activities with maintenance personnel, and minimize downtime by implementing effective MTTR and MTBF strategies.
Enforce shop floor safety, PPE usage, lockout/tagout procedures, and environmental regulations while promoting a culture of safety-first and continuous learning.
Coordinate with production planning, purchasing and supply chain teams to manage work orders, material availability, and lead times for long-lead tooling or fixtures.
Manage change control for process documentation, routings, and work instructions, ensuring all production staff have current, accessible procedures and tooling lists.
Lead new product introductions (NPI) for machined components, including capability studies, run plans, pilot builds and cross-functional readiness reviews with engineering, quality and planning.
Control scrap, rework and non-conforming parts by implementing containment, identifying root causes, and driving permanent corrective actions to improve first-pass yield.
Mentor operators in basic programming, tooling changes, and setup best practices to build internal bench strength and reduce reliance on external programmers.
Support cost reduction initiatives through cycle time reduction, material utilization improvements and standardized work to positively impact part cost and margin.
Manage supplier relationships for critical tooling, cutters, and accessories; evaluate supplier performance and ensure timely delivery of quality tooling at competitive prices.
Coordinate multi-shift handovers, maintain clear shift logs, and ensure continuity of actions and issue resolution between shifts.
Maintain accurate BOMs, tooling lists, and NC program libraries in the company’s ERP or PDM system for traceability and repeatability.
Implement and monitor process capability (Cp/Cpk) for critical features and work with engineering on design for manufacturability (DFM) suggestions to simplify production.
Participate in customer audits, technical reviews and supplier audits as needed to demonstrate machining capability, quality controls and continuous improvement outcomes.

Secondary Functions

Support production scheduling adjustment requests and provide realistic machine capacity and setup time estimates to planning and customer service teams.
Contribute to departmental budgeting and capital equipment proposals by providing cost/benefit analysis for new machines, automation, or tooling investments.
Collaborate with HR to define role descriptions, hiring criteria and onboarding programs for CNC roles to sustain required staffing levels and skills.
Participate in cross-functional Kaizen events and lean workshops to spread best practices and standard work across manufacturing cells.
Maintain and update training matrices, SOPs and competency records for machining personnel to ensure compliance and skills traceability.
Serve as the technical escalation point for machining-related supplier quality issues or warranty claims requiring forensic machining expertise.
Assist continuous improvement teams in capturing data for process control and implementing shop floor digitalization initiatives (e.g., tool monitoring, OEE tracking).
Act as subject matter expert for machining capability when quoting new business or providing technical input to sales and estimating teams.
