What this role is
Experienced individual contributor who programs, sets up, and operates CNC and robotic machining equipment to produce complex precision parts with minimal oversight. At the Senior Professional (P4) level, the role owns a system or set of related features, devises new approaches, and drives multi-team / function outcomes. Technical lead for focused efforts; mentors several.
What this level does
- Collaborates with engineers to optimize machining processes — revising speeds, feeds, tool paths, and fixturing to cut cycle time and scrap on complex or hard-to-hold parts
- Serves as the technical problem-solver for jobs others cannot get to run, isolating root cause across program, machine, tooling, and material variables
- Develops and proves out new machining processes for difficult parts, selecting methods and work-holding rather than following a fixed routing
- Leads the machining of complex, close-tolerance components and reviews other machinists' setups and programs before release to production
- Maintains equipment reliability and drives corrective action when recurring dimensional or surface-finish problems appear across a part family
- Knowledge applied
- Applies in-depth expertise to optimize processes and prove out difficult parts, selecting methods, work-holding, and toolpaths rather than following a fixed routing.
- Complexity & problem solving
- Performs in-depth analysis of complex, interacting machining variables to solve jobs others cannot run and reduce scrap on a part family.
- Collaboration & interaction
- Coordinates with engineers and other machinists, reviews their setups and programs, and may lead the machining of complex components.
- Typical experience
- 8+ years, with deep experience on close-tolerance and complex machining work.
Skills at this level
- Machine operation and setup
- — Sets up and troubleshoots mills, lathes, drill presses, grinders, hones, and CNC centers, applying good manufacturing practices and selecting tooling and machining resources appropriate to the part being made.
- CNC programming (G-code)
- — Generates and modifies programmatic G-code instructions that the machine interprets to cut components, applying knowledge of speeds and feeds, machine tooling, work-holding, and material behavior.
- Blueprint and GD&T reading
- — Reads blueprints and Geometric Dimensioning and Tolerancing callouts to interpret datums, position, profile, and dimensional specifications for a part before machining and inspection.
- Precision measurement and inspection
- — Reads instrumentation and gauges to measure machined dimensions within a .001 tolerance, performing first-article and in-process inspections to confirm parts meet the print.
- Machining mathematics
- — Uses trigonometry and shop math to follow technical drawings and calculate part dimensions, tool positions, machine speeds, and feed rates for precision work.
- Machining process optimization
- — Revises speeds, feeds, toolpaths, sequencing, and fixturing in collaboration with engineers to reduce cycle time and scrap and improve the capability of an entire machining process.
- Fault diagnosis and troubleshooting
- — Diagnoses machining problems by isolating root cause across program, machine, tooling, fixture, and material, using logic and reasoning to weigh alternative fixes.
- Tooling and equipment maintenance
- — Maintains machine tools and manages tooling inventory, monitoring cutter wear and equipment condition to keep parts within tolerance and machines running reliably.
- Fabrication and part repair
- — Fabricates, reconstructs, and repairs mechanical parts and tooling from detailed blueprints, including welding and manual finishing where the routing is not fully defined.
- Failure prediction through analysis
- — Predicts where tolerance stacks, thermal growth, tool deflection, and fixturing will cause a part to fail before it is cut, so high-consequence jobs run correctly the first time.
- Shop mentorship and training
- — Trains junior and senior machinists on setup, programming, and inspection, and establishes proven standard methods that others in the shop adopt.
