Position Summary

The CNC Machinist III is the shop's most capable and self-directed machinist — the person who takes the difficult job, the tight tolerance, the new part, or the problem machine and returns it to production without hand-holding. The role is defined by three things: independent setup and prove-out across the full range of assigned work centers including multi-axis and mill-turn, ownership of dimensional quality and process at the machine, and the ability to develop other machinists.

Unlike Levels I and II, the Machinist III works from prints and models rather than proven paperwork, authors and restructures programs at the control, and designs the fixturing and process rather than executing someone else's. This is the top rung of the machinist ladder and the direct feeder into CNC Leadman. Competencies are defined and assessed in the Skills Matrix.

• Set up and prove out new, revised, and undocumented parts from print or model across all assigned work centers, including multi-axis and mill-turn — planning sequence, tooling, work holding, and process without direction.
• Author, restructure, and optimize programs at the control, including canned cycles, subprograms, work offset structures, and macro or parametric routines where required.
• Own process decisions for new and problem work — operation sequence, tooling and insert grade, work holding strategy, cutting conditions, and cycle-time approach — and document them for repeatability.
• Hold the tightest tolerances and finishes produced in the shop, including work on difficult material, thin-wall and long-reach parts, and features requiring indicated location.
• Design and specify fixtures, soft jaws, arbors, holding devices, and checking gauges; fabricate or coordinate their manufacture to support production.
• Interpret prints, models, and GD&T fully — datums, feature control frames, true position, profile, runout, and tolerance stack-up — and translate them into setup and inspection decisions.
• Apply trigonometry and advanced shop math to compound angles, bolt circles, tapers, rotary and indexed work, and dimensional stack-ups.
• Own dimensional quality on the work performed; support and interpret first-article inspection, translate inspection findings into process corrections, and contain nonconforming material per quality procedure.
• Recover machines and processes from crashes, alarms, and interruptions; re-establish setups, requalify parts, and determine root cause rather than restarting blind.
• Diagnose and correct chatter, poor finish, dimensional drift, tool life, chip control, work holding movement, and thermal effects; separate process problems from machine problems and partner with maintenance on the latter.
• Support programming and engineering on new work — tooling, work holding, sequence, fixturing, and cycle-time feedback from the floor — and support quoting with realistic cycle and setup estimates.
• Train and mentor Machinist I and II and operator personnel; sign off setup, machine, and skill competency as authorized by the supervisor.
• Author and correct setup sheets, tool lists, and work instructions so jobs are repeatable by the crew; drive tooling standardization across the cell.
• Drive scrap and rework reduction, cycle-time improvement, preventive maintenance compliance, and 5S in the assigned area.
• Follow and enforce all safety rules,…
