CNC Machinist III - Mills or Lathes

P & F Industries•Cranberry Township, PA

20h•$34 - $44•Onsite

About The Position

The CNC Machinist III is the most capable and self-directed machinist in the shop, responsible for handling difficult jobs, tight tolerances, and new parts. This role involves independent setup and prove-out across a full range of assigned workcenters, including multi-axis and mill-turn. The position requires ownership of dimensional quality and process at the machine, as well as the ability to develop other machinists. Unlike lower levels, the Machinist III works from prints and models, authors and restructures programs at the control, and designs fixturing and processes. This is the top-tier machinist role, feeding directly into the CNC Leadman position.

Requirements

9+ years of relevant work experience in CNC machining, or equivalent progression from CNC Machinist II with all Skills Matrix competencies above met and verified.
Demonstrated ability to take a new or undocumented part from print or model to a proven, repeatable process without supervision.
Demonstrated multi-axis or mill-turn setup and prove-out capability, and program authoring at the control.
Full working command of precision measuring equipment and first-article verification.
High school diploma or GED.
Completed workcenter qualification cards across all CNC categories, with training and competency sign-off authority granted by the supervisor.
Stands and walks on a concrete shop floor for the majority of an 8- to 12-hour shift, including overtime and weekend work as scheduled.
Frequent bending, reaching, twisting, kneeling, and overhead reaching to load, unload, and reach into machine work zones.
Frequently lifts, carries, pushes, and pulls up to 35 lbs unassisted; heavier material and workholding moved with carts, hoists, and lift assists.
Sustained fine motor control and hand-eye coordination for gauging, tool handling, and offset entry.
Vision correctable to read prints, dial and digital gauges, and control screens.
Exposure to cutting fluid and coolant mist, oils, metal chips, moving machinery, elevated noise, and seasonal temperature variation.
Required PPE includes safety glasses with side shields, hearing protection, appropriate footwear, and cut-resistant gloves where specified.
No loose clothing, jewelry, or unrestrained long hair near rotating equipment.
Dependable attendance and punctuality.
Communicates clearly with supervision, quality, and maintenance.
Takes direction and asks before deviating.
Owns and corrects mistakes.
Works safely and cooperatively.
Flexible on shift and overtime as production requires.

Nice To Haves

Apprenticeship completion or journeyman status.
CAM programming experience.
Fixture design experience.
Prior experience training machinists.
Machining certificate or diploma from a technical school.
Completion of a formal machinist apprenticeship.
Journeyman card.
NIMS credentials in turning, milling, and CNC programming.

Responsibilities

Set up and prove out new, revised, and undocumented parts from print or model across all assigned workcenters, including multi-axis and mill-turn — planning sequence, tooling, workholding, 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, workholding 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, workholding 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, workholding, 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, lockout/tagout, machine guarding, and PPE requirements; correct unsafe conditions and report near-misses. Maintain accurate labor, quantity, and scrap reporting in the shop system.
