Toolmaker Course

Lesson 1 • The Toolmaking Trade Overview

Defines the toolmaker role, industry scope, and career pathways. Establishes context for all subsequent technical learning in the course.

Lesson 2 • Engineering Drawing Basics

Introduces orthographic projection, dimensioning, and tolerance notation. Drawing literacy is prerequisite for interpreting all tooling specifications ahead.

Lesson 3 • Measurement and Inspection Basics

Teaches use of rules, calipers, and micrometers to verify dimensions. Accurate measurement underpins quality control in all subsequent work.

Lesson 4 • Toolmaking Materials Introduction

Surveys ferrous and non-ferrous metals, plastics, and carbide used in tooling. Material selection principles recur in every fabrication chapter.

Lesson 1 • Surface Plate and Layout Work

Introduces granite surface plates, height gauges, and angle plates for layout. Accurate layout transfers drawing dimensions to raw stock before machining.

Lesson 2 • Gauge Types and Applications

Covers plug, ring, snap, and thread gauges for go/no-go inspection. Gauge selection directly supports tolerance verification in tooling work.

Lesson 3 • Geometric Tolerancing Verification

Applies GD&T concepts to measure flatness, roundness, and perpendicularity. Connects drawing callouts from Chapter 1 to physical inspection methods.

Lesson 4 • Inspection Documentation and Reporting

Covers first-article inspection reports, measurement uncertainty, and traceability. Proper records support quality systems and tooling approval processes.

Lesson 1 • Engine Lathe Setup and Operation

Covers chuck work, between-centers turning, and taper cutting on the engine lathe. Lathe skills form the core of rotational component production in toolmaking.

Lesson 2 • Milling Machine Fundamentals

Teaches knee mill setup, cutter selection, and climb vs. conventional milling. Milling produces flat surfaces, slots, and pockets central to die and fixture work.

Lesson 3 • Drilling, Reaming, and Tapping

Covers drill press setup, hole location, reaming to size, and hand tapping. Accurate holes are critical in die sets, fixtures, and mold components.

Lesson 4 • Surface Finish and Dimensional Control

Teaches finishing cuts, surface roughness measurement, and in-process gauging. Dimensional control during machining prevents costly rework on precision tooling.

Lesson 1 • Tempering and Stress Relieving

Covers tempering cycles, double tempering, and stress relief annealing. Tempering reduces brittleness while retaining hardness in finished tooling components.

Lesson 2 • Metallurgy Essentials for Toolmakers

Covers iron-carbon phase diagrams, grain structure, and alloying effects. Metallurgical knowledge enables informed material and treatment selection for tooling.

Lesson 3 • Hardening and Quenching Processes

Explains austenitizing temperatures, quench media, and distortion control. Correct hardening produces the wear resistance required in cutting and forming tools.

Lesson 4 • Case Hardening Methods

Introduces carburizing, nitriding, and induction hardening for surface hardness. Case hardening extends tool life where core toughness must be preserved.

Lesson 1 • Tool and Cutter Grinding

Teaches resharpening of end mills, drills, and form tools on the tool grinder. Maintaining sharp cutting tools reduces cost and maintains machining accuracy.

Lesson 2 • Cylindrical and Internal Grinding

Covers between-centers and centerless grinding of shafts, pins, and bores. Cylindrical grinding achieves the roundness and size tolerances needed in punch and die sets.

Lesson 3 • Lapping, Honing, and Polishing

Introduces abrasive lapping, bore honing, and hand polishing for final finishes. These processes achieve surface roughness and fit quality beyond grinding capability.

Lesson 4 • Surface Grinding Techniques

Teaches magnetic chuck setup, depth of cut, and cross-feed strategies. Surface grinding produces flat reference surfaces and precise thickness on tooling plates.

Lesson 1 • CNC Machine Fundamentals and Setup

Covers machine axes, coordinate systems, and work offset setting on CNC machining centers. Correct setup is the foundation for accurate CNC tooling production.

Lesson 2 • Process Optimization and Quality Verification

Teaches feeds and speeds optimization, in-process probing, and first-article verification on CNC parts. Optimized processes reduce cycle time while maintaining tooling tolerances.

Lesson 3 • CNC Turning for Tooling Components

Covers turning center setup, live tooling, and sub-spindle operations for round tooling parts. CNC turning complements milling for complete tooling component production.

Lesson 4 • CAM Software for Tooling Applications

Introduces CAM toolpath strategies for 2.5D and 3D tooling surfaces. CAM output is verified against manual programming knowledge to catch errors before cutting.

Lesson 1 • Locating and Clamping Principles

Explains the 3-2-1 locating principle, datum selection, and clamping force direction. These principles govern all fixture designs produced in this and later chapters.

Lesson 2 • Drill Jig Design and Construction

Covers jig body design, drill bushing selection, and leaf vs. box jig configurations. Drill jigs ensure repeatable hole location across production quantities.

Lesson 3 • Fixture Fabrication and Assembly

Covers material selection, component machining, and assembly sequence for fixtures. Fabrication skills from Chapters 3 and 5 are applied to produce complete assemblies.

Lesson 4 • Fixture Verification and Tryout

Teaches dimensional verification of locators, trial machining, and fixture sign-off. Verified fixtures prevent scrap and ensure process capability before production.

Lesson 1 • Blanking and Piercing Die Design

Covers clearance calculation, punch and die size relationships, and strip layout. Correct clearance determines cut quality and die life in blanking operations.

Lesson 2 • Die Assembly, Tryout, and Sharpening

Teaches assembly sequence, press tryout, and die sharpening to restore cutting edges. Proper tryout and maintenance extend die life and maintain part quality.

Lesson 3 • Forming and Bending Die Design

Explains springback compensation, bend radius selection, and blank development. Forming die geometry must account for material behavior to achieve final part shape.

Lesson 4 • Die Set Components and Terminology

Introduces die shoes, guide posts, bushings, punches, and stripper plates. Component knowledge is essential before designing or fabricating any die assembly.
