Core Responsibilities

Primary Functions

Conduct initial machine setup and configuration at the start of each production run, including calibration, cleaning, and tooling changes, to ensure alignment with specific job orders and blueprints.
Diligently monitor and control machine operations, actively adjusting settings such as speed, feed rate, temperature, and pressure to maintain optimal performance and product quality.
Safely and accurately load raw materials, workpieces, or components into machinery, whether semi-automated or fully automated, ensuring a continuous and efficient production flow.
Perform rigorous in-process and final quality inspections on parts and finished products using precision measuring tools like calipers, micrometers, gauges, and coordinate measuring machines (CMM).
Interpret and work from technical documents, including blueprints, engineering drawings, schematics, and work orders, to produce parts that meet exact specifications and tolerances.
Execute routine and preventative maintenance tasks on machinery, such as lubrication, cleaning, and minor repairs, to minimize downtime and extend equipment life.
Identify, troubleshoot, and resolve minor operational problems and machine malfunctions in a timely manner, escalating complex issues to maintenance technicians or supervisors.
Maintain a clean, organized, and safe work area by adhering to 5S principles and company-wide safety protocols, including Lockout/Tagout (LOTO) procedures.
Accurately complete all required production documentation, including logs, quality reports, and output records, using both paper-based and digital systems (MES).
Observe machine operations to detect and diagnose abnormalities, such as worn tools, material defects, or unusual mechanical sounds, and take appropriate corrective action.
Unload finished parts or products from the machine, performing any necessary secondary operations like deburring, cleaning, or assembly before staging them for the next process.
Collaborate effectively with team members, supervisors, and quality control personnel to ensure production goals and quality standards are consistently met.
Manage the inventory of raw materials and supplies at the workstation, notifying supervisors or material handlers when replenishment is needed to prevent production stoppages.
Adhere strictly to all health, safety, and environmental (HSE) regulations and policies to foster a secure working environment for oneself and colleagues.
Participate in continuous improvement initiatives, providing valuable feedback and suggestions for enhancing process efficiency, safety, and product quality.
Change out and set up tooling, dies, and fixtures as required for different production jobs, ensuring proper alignment and secure installation.
Operate material handling equipment, such as pallet jacks or forklifts, to move raw materials and finished goods within the production facility (if certified).
Perform first-article inspections to verify that the initial part produced in a run meets all dimensional and quality requirements before proceeding with full production.
Monitor and manage the flow of coolants and lubricants, ensuring proper levels and functionality to prevent tool wear and overheating.
Assist in the training and mentoring of new or less experienced operators, sharing knowledge of machine operation, safety procedures, and quality standards.
Package and label finished products according to customer specifications and internal standards, ensuring they are ready for shipment or storage.
Verify that all safety guards and emergency stops on the machinery are functioning correctly before and during each shift.

Secondary Functions

Assist in periodic inventory counts and material reconciliation activities.
Contribute to team meetings and problem-solving sessions to address production challenges.
Support maintenance technicians during more complex repairs or equipment installations.
Participate in cross-training programs to learn the operation of other machinery within the facility.
