🎯 Role Definition

An Outside Machinist is a skilled tradesperson responsible for producing, modifying, and repairing precision metal parts using manual and semi-automated machine tools on the shop floor. This role focuses on setting up and operating manual lathes, vertical and horizontal milling machines, grinders, and drill presses to manufacture components to engineering drawings and tight tolerances. The Outside Machinist will read blueprints and GD&T, select and dress tooling, inspect finished parts with precision metrology instruments, and collaborate with production planners and quality teams to meet delivery and quality objectives. Ideal candidates demonstrate strong mechanical aptitude, shop-floor decision-making, and a safety-first mindset.

Core Responsibilities

Primary Functions

  • Interpret and work from engineering drawings, blueprints, sketches, and specifications to produce precision outside-turned and milled components to specified dimensions and tolerances using manual lathes, vertical/horizontal milling machines, and auxiliary equipment.
  • Set up and operate manual engine lathes to perform turning, facing, threading, grooving, boring, and knurling operations; choose speeds, feeds, and tooling for optimal surface finish and dimensional accuracy.
  • Set up and operate manual and turret milling machines, including vertical and horizontal mills, to perform complex milling operations such as slotting, contouring, keyway cutting, and dovetailing with correct fixturing and workholding.
  • Operate and maintain surface grinders and cylindrical grinders to achieve mirror-finish surfaces and tight surface finish specifications, ensuring proper wheel dressing and coolant application.
  • Perform job setup: select, grind, and dress cutting tools, install fixtures, check runout, and optimize machine parameters to ensure first-article success and minimize scrap.
  • Execute precision measurement and inspection using micrometers, dial indicators, vernier calipers, height gauges, bore gauges, surface plates, and optical comparators to validate conformance to drawings and GD&T requirements.
  • Conduct in-process and final inspections, document measurement results, record non-conformances, and work with Quality Assurance to disposition defective items or recommend rework.
  • Make setup and tooling adjustments on the fly to maintain part quality, troubleshoot machining issues (chatter, tool breakage, dimensional drift), and implement corrective actions to stabilize processes.
  • Perform simple on-machine programming or hand inputs for conversational/manual CNC controls when required; translate setup notes and fixture offsets for downstream CNC processes.
  • Maintain and sharpen tooling as required (tool bits, inserts, drills), manage tooling inventory, and recommend tooling upgrades or alternate cutting strategies to improve cycle time and tool life.
  • Read and apply Geometric Dimensioning & Tolerancing (GD&T) symbols and callouts to assure proper orientation, datum structure, and tolerances for assembled components.
  • Work from sketches or verbal instructions to reverse-engineer or repair worn parts and field service components to restore equipment function, often under time constraints for customer downtime recovery.
  • Follow job travelers, work orders, routing sheets, and production schedules to ensure on-time completion and proper documentation of produced quantities and hours.
  • Adhere strictly to shop safety policies, lockout/tagout procedures, machine guarding requirements, and personal protective equipment (PPE) protocols to prevent injury and maintain a compliant workplace.
  • Maintain machine cleanliness and lubrication schedules, perform daily preventive maintenance checks, and escalate mechanical abnormalities or failures to maintenance staff.
  • Communicate with production planners, QC inspectors, and engineers about lead times, potential design or process improvements, and tooling needs to optimize throughput and reduce cost.
  • Train apprentices and less-experienced machinists on best practices for setup, safe operation, measurement techniques, and finishing operations to build bench strength.
  • Document setup sheets, tooling lists, and process notes so that successful setups can be repeated consistently across shifts and by other machinists.
  • Apply lean manufacturing principles where appropriate—5S, Kaizen, and waste reduction—to improve flow, reduce setup times, and increase shop capacity.
  • Implement quality corrective actions when nonconformances are discovered, update inspection criteria, and assist in root cause analysis and corrective/preventive action (CAPA) implementation.

Secondary Functions

  • Support engineering and production teams by providing feedback on manufacturability, tolerancing, and material selection to reduce machining cost and complexity.
  • Assist with developing work instructions, standard operating procedures (SOPs), and process documentation for recurring jobs and new product introductions.
  • Aid in continuous improvement projects by proposing fixture designs, tooling standardization, and sequence changes to decrease cycle time and improve consistency.
  • Participate in downtime recovery efforts and rapid-response repair jobs for customer equipment or internal assemblies, including limited field service travel when required.
  • Keep tooling and spare parts inventory organized and report low-stock items; recommend vendor or specification changes to improve availability and tool life.
  • Collaborate with Quality to implement sample plans, in-process gauges, and poka-yoke checks to prevent escapes and support ISO/AS compliance initiatives.
  • Mentor and cross-train with other shop functions (CNC, welding, assembly) to create multi-skilled teams and improve scheduling flexibility.
  • Participate in weekly production planning reviews and escalation meetings to align priorities, communicate risks, and mitigate order delays.

Required Skills & Competencies

Hard Skills (Technical)

  • Proven proficiency on manual lathes (engine/center lathes) including turning, facing, threading, boring, and form tool work.
  • Skilled at vertical and horizontal milling machine setup and operation, including complex fixture layout and multi-step milling.
  • Experience with surface and cylindrical grinding techniques, wheel selection, dressing, and maintaining surface finish targets.
  • Strong blueprint reading and interpretation skills, including application of GD&T, geometric callouts, finish symbols, and tolerance stacks.
  • Advanced use of precision metrology: micrometers, vernier calipers, dial indicators, bore gauges, height gauges, surface plates, and optical comparator.
  • Capability to perform manual tool grinding and basic sharpening of single-point tools and cutters.
  • Knowledge of shop math, trigonometry, and feeds & speeds calculations to select cutting parameters for different materials (steel, stainless, aluminum, bronze).
  • Ability to create and follow detailed setup sheets, tooling lists, and inspection documentation; familiarity with ERP/MRP or job tracking systems is a plus.
  • Experience with conversational/manual CNC controls and ability to transfer setup knowledge to CNC operators; familiarity with CAM/Mastercam is beneficial.
  • Competence in preventive maintenance checks, troubleshooting mechanical problems, and coordinating repairs with maintenance teams.
  • Familiarity with heat treatment effects, surface finishes, and post-machining deburring and finishing techniques.
  • Working knowledge of shop safety standards, lockout/tagout, and applicable regulatory or quality system requirements (ISO 9001, AS9100 preferred).
