Day 1 on the Tool Design Engineer path.

What a Tool Design Engineer does

Designs molds, dies, and fixtures for manufacturing teams so parts can be made safely, accurately, and on time.

  • Design molds, dies, jigs, and fixtures to meet part specs and production targets
  • Create 3D CAD models and 2D drawings with dimensions, tolerances, and notes
  • Select materials and standard components for strength, wear, and cost
  • Review designs with manufacturing, quality, and suppliers to prevent issues
  • Run basic checks for fit, clearance, and forces to reduce tool failure risk
  • Support tool build, tryout, and first production runs; troubleshoot problems
  • Update designs and documentation after changes, tests, or quality findings

A day in the life

  1. Check production issues and prioritize tool fixes with manufacturing and quality
  2. Model a new fixture in CAD and release drawings for machining or fabrication
  3. Join a design review to confirm tolerances, safety, and ease of use on the line
  4. Visit the shop floor to measure parts, watch a tryout, and adjust the design

Tools you will use

CAD: SolidWorks, Autodesk Inventor, CATIA2D drawings: GD&T, drawing standardsPrototyping: 3D printing, basic machiningMetrology: calipers, micrometers, CMMAnalysis: hand calculations, basic FEAPlanning: checklists, Gantt charts
