CNC Machinist II - Mills or Lathes

P & F Industries•Cranberry Township, PA

20h•$30 - $40•Onsite

About The Position

The CNC Machinist II sets up, proves out, and runs CNC work independently across turning and machining centers, and owns the process decisions that go with it — operation sequence, tooling and insert selection, workholding, and cutting conditions. The role works from prints and models rather than proven paperwork, edits and corrects programs at the control, and brings new and revised parts into tolerance without supervision. The Machinist II is the shop's dependable CNC capability: the person given the job that has to run right the first time. Multi-axis and mill-turn prove-out, fixture and process design, and training sign-off remain with Level III. Competencies are defined and assessed in the Skills Matrix.

Requirements

Program G/M-code and canned cycles and make minor edits to run new jobs
Prove out CAM programs and collaborate with CAM to release parts
Troubleshoot chatter, drift and finish to maintain quality
Operate 4-axis, live tooling and fixturing to produce complex parts
Operate bar-feed / robot machines to increase throughput
Analyze more complex machines (dual-turret, dual-spindle) to run them proficiently
Optimize time and efficiency to meet ~85% utilization
Set up, prove out, and run unassisted: CNC lathes, including live-tool and bar-fed turning centers; CNC vertical and horizontal machining centers.
6–9 years of relevant work experience in CNC machining, or equivalent progression from CNC Machinist I with all Skills Matrix competencies above met and verified.
Demonstrated ability to set up and prove out work independently and to hold close tolerances and specified finishes on production work.
Fluency with the shop's CNC controls, including program editing and offset structures.
High school diploma or GED.

Nice To Haves

Multi-axis and mill-turn prove-out, fixture and process design, and training sign-off remain with Level III.
Working proficiency — run unassisted, set up with guidance: CNC mill-turn and multi-axis turning centers; twin-spindle lathes. Active development on at least one multi-axis workcenter is expected.
As assigned: CNC OD grinding and CNC gear equipment; manual lathes, mills, grinders, saws, and presses in support of CNC production.
Apprenticeship completion
Multi-axis or mill-turn exposure
CAM experience
Manual machining background
Machining certificate or diploma from a technical school
Completion of a formal machinist apprenticeship
NIMS credentials in turning, milling, and CNC programming.

Responsibilities

Perform complete setups independently on CNC turning and machining centers — workholding, tooling, program load, offsets, and first-piece qualification — without supervision.
Prove out new and revised programs at the control, correcting toolpaths, offsets, feeds, and speeds to bring parts into tolerance and cycle time.
Decide operation sequence, tooling and insert grade, workholding, and cutting conditions for new and problem parts; document the decisions so the job is repeatable.
Edit and correct programs at the control, including canned cycles, work and tool offset structures, and subprogram calls.
Interpret prints, models, and GD&T — datums, feature control frames, position tolerance, profile, and runout — and translate them into setup and inspection decisions.
Apply trigonometry and shop math to bolt circles, angles, tapers, compound setups, and dimensional stack-ups.
Own dimensional quality at the machine using the full range of precision measuring equipment, indicators, height gauges, gauge blocks, and comparators; present and support first-article inspection.
Fabricate or specify simple fixtures, soft jaws, stops, and holding devices required to run the work.
Recover machines and processes after alarms, crashes, and interruptions; re-establish offsets and requalify parts before returning to production.
Diagnose and correct process problems — chatter, poor finish, dimensional drift, tool life, chip control, workholding movement — and separate process problems from machine problems.
Report mechanical faults to maintenance with accurate symptom detail; support repair and requalification.
Contain nonconforming material and escalate per quality procedure; do not run through a known nonconformance.
Support and orient Machinist I and operator personnel on assigned workcenters; provide programming feedback on tooling, workholding, and cycle time from the floor.
Author and correct setup sheets, tool lists, and work instructions so jobs are repeatable by others; contribute to scrap reduction, tooling standardization, and 5S.
Follow all safety rules, lockout/tagout, machine guarding, and PPE requirements without exception; report unsafe conditions and near-misses. Maintain accurate labor, quantity, and scrap reporting in the shop system.
