Core Responsibilities

Primary Functions

Analyze and interpret complex engineering drawings, blueprints, and 3D CAD models to determine the optimal sequence of operations for fabricating tools and dies.
Set up and skillfully operate a wide variety of machine tools, both manual and CNC (e.g., lathes, milling machines, surface grinders, EDM machines), to produce precision components within extremely tight tolerances.
Perform intricate bench work, including the precise fitting, filing, scraping, and aligning of tool and die components to ensure perfect function and assembly.
Construct, assemble, and commission new stamping dies (progressive, compound, transfer), injection molds, jigs, and fixtures from raw stock and components.
Conduct comprehensive troubleshooting and diagnostic analysis on existing production tooling to identify the root cause of part defects, machine malfunctions, or premature wear.
Execute complex repairs and perform preventative maintenance on dies and molds, which often includes precision welding, grinding, and replacing worn or broken sections to restore them to original specifications.
Utilize a full range of precision measuring instruments, such as micrometers, indicators, gauge blocks, and coordinate measuring machines (CMM), to verify part dimensions and geometric conformity.
Collaborate directly with production and engineering teams to perform tool tryouts, validating that new or repaired tooling functions correctly under production conditions.
Machine and fabricate unique or hard-to-find replacement parts for tooling and production equipment as needed, often working with minimal direct supervision.
Read and apply Geometric Dimensioning and Tolerancing (GD&T) principles to ensure parts are manufactured and inspected correctly according to design intent.
Program, set up, and operate Wire EDM and Sinker EDM machines for creating intricate shapes, sharp corners, and features that are difficult or impossible to machine conventionally.
Test completed tools and dies to ensure they are fully operational and produce parts that consistently align with all engineering specifications and quality control standards.
Mentor and train apprentice toolmakers, sharing critical knowledge and best practices to develop the next generation of skilled tradespeople.
Select appropriate metals and materials for tooling projects based on their properties, heat treatment requirements, and the specific application's demands.
Perform or manage the heat treating and hardening processes for tool components to achieve desired durability, toughness, and wear resistance.

Secondary Functions

Provide expert technical support and troubleshooting expertise to production teams on the floor to resolve tooling-related issues and minimize equipment downtime.
Contribute to the organization's continuous improvement (Kaizen) initiatives by recommending and implementing modifications to tooling designs and fabrication processes.
Collaborate with design and manufacturing engineers during the design phase to provide feedback on manufacturability (DFM) and ensure new tool designs are robust and production-ready.
Participate in project planning and review meetings, providing accurate time estimates and technical feedback for new tooling builds and major repair projects.
