Core Responsibilities

Primary Functions

Analyze and interpret complex blueprints, engineering sketches, 3D CAD models, and geometric dimensioning and tolerancing (GD&T) to determine fabrication methods and operational sequences.
Set up, program, and operate a variety of CNC and manual machine tools, including lathes, milling machines, surface grinders, and electrical discharge machines (EDM), to produce high-precision tooling.
Fabricate, fit, and assemble components to build and repair a wide range of tools, progressive dies, stamping dies, injection molds, jigs, and fixtures according to exacting specifications.
Perform intricate bench work, including hand-fitting, lapping, polishing, and scraping, to achieve critical alignments, finishes, and clearances on tooling assemblies.
Conduct diagnostic testing and systematic troubleshooting on malfunctioning or underperforming tools and dies, identifying root causes of failures and implementing effective, long-lasting repairs.
Verify dimensional accuracy of machined parts and assembled tools using advanced precision measuring instruments such as micrometers, calipers, height gauges, bore gauges, and Coordinate Measuring Machines (CMM).
Execute preventative maintenance schedules on all production tooling to minimize unexpected downtime and extend the operational life of these critical assets.
Work directly with stamping presses or molding machines to spot and fit new tooling, performing trial runs to ensure tools produce parts that meet all quality and production standards.
Select appropriate metals, alloys, and other materials for tooling projects based on specifications, strength requirements, heat treatment, and wear resistance.
Perform and manage heat-treating processes for various tool steels to achieve required hardness, toughness, and durability.
Develop and document standardized procedures for tool setup, maintenance, and repair to ensure consistency and knowledge transfer within the team.
Read and interpret CMM reports to make necessary adjustments or modifications to tooling to bring parts into conformance with specifications.
Plan and lay out work, calculating and determining machine settings, cutting tools, speeds, and feeds required for each operation.
Safely operate overhead cranes, forklifts, and other material handling equipment to move large dies and tooling components.
Perform TIG or laser welding to repair cracks, chips, or wear on die components, followed by re-machining to original specifications.
Participate in design review meetings with engineering teams, providing critical feedback on the manufacturability, durability, and serviceability of new tool designs.
Maintain a clean, organized, and safe work environment in the tool room, adhering to all company safety protocols and 5S principles.
Document all tool modifications, repairs, and maintenance activities in the Computerized Maintenance Management System (CMMS) for historical tracking and analysis.
Assist in estimating time and material costs for the fabrication and repair of tooling to support project planning and budgeting.
Mentor and train apprentices and junior-level machinists, sharing knowledge of advanced techniques and best practices in tool and die making.

Secondary Functions

Collaborate with the Quality Assurance department to resolve part quality issues that are directly related to tooling performance.
Participate in continuous improvement (Kaizen) events aimed at optimizing tool room workflow, reducing setup times, and increasing production efficiency.
Support the R&D department by fabricating prototype components and fixtures for new product development projects.
Maintain inventory levels of spare parts, tooling components, and raw materials needed for timely repairs and fabrication projects.
