Full Time Intermediate Cranberry Township, PA, US

Salary Range: $30.00 To $40.00 Hourly

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, work holding, 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.

• Perform complete setups independently on CNC turning and machining centers — work holding, 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, work holding, 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, work holding 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 work centers; provide programming feedback on tooling, work holding, 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.
• 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
