What this role is

Sets up and operates computer-controlled machining equipment to produce parts to specification. At the Developing Professional (P2) level, the role owns defined deliverables / small features, applies established patterns, and drives own and immediate-team deliverables. May guide interns.

What this level does

  • Sets up basic machining jobs from setup sheets and verbal instructions and independently runs a variety of machines including CNC milling and turning centers
  • Reads instrumentation and gauges to measure part dimensions within a .001 tolerance and reworks or scraps parts that miss the print
  • Analyzes drawings, blueprints, and design data to calculate correct part dimensions, select tooling, and set machine speeds and feed rates
  • Operates and maintains common machine shop tools — mills, lathes, drill presses, grinders, hones, and welders — for routine fabrication and repair jobs
  • Programs and modifies simple CNC codes to correct offsets, add passes, or adjust feeds during a running job
Knowledge applied
Applies defined machining procedures — setup sheets, speeds/feeds, tolerance measurement to .001 — across mills, lathes, and CNC centers in familiar contexts.
Complexity & problem solving
Uses judgment on conventional jobs: selects tooling, calculates dimensions, and modifies simple CNC codes; refers unusual setups upward.
Collaboration & interaction
Builds working relationships with senior machinists and inspectors; takes and follows general instruction with some routine independence.
Typical experience
2+ years of shop-floor machining, or completion of a machinist training program.

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.
