Lesson 2 • Cutting Tool Anatomy

Breaks down blade geometry, edge angles, and tool composition. Correct tool identification is prerequisite to safe and effective operation.

Lesson 3 • Material Properties and Behavior

Examines how hardness, grain, and ductility affect cut quality. Understanding material behavior prevents tool damage and poor results.

Lesson 4 • Measurement and Layout Fundamentals

Introduces measuring tools, marking techniques, and tolerance concepts essential for accurate cuts. Precision layout directly determines cut accuracy.

Lesson 1 • Chisel and Gouge Techniques

Introduces mallet-driven and hand-pressure chisel work for notching, paring, and mortising. Bevel orientation and mallet control determine cut quality.

Lesson 2 • Shears and Snips for Sheet Material

Demonstrates shear mechanics for cutting sheet stock, fabric, and thin metal. Proper jaw alignment prevents distortion and burr formation.

Lesson 3 • Workholding and Support Strategies

Explains clamping, vises, and bench stops that stabilize workpieces during hand cutting. Secure workholding is critical for accuracy and injury prevention.

Lesson 4 • Knife and Blade Control

Teaches grip, stance, and stroke mechanics for utility and craft knives. Controlled blade pressure prevents slipping and ensures clean separation.

Lesson 1 • Circular Saw Setup and Use

Covers blade selection, depth setting, fence use, and feed rate for circular saws. Correct setup prevents kickback and produces consistent straight cuts.

Lesson 2 • Dust, Chip, and Noise Management

Explains extraction systems, chip deflectors, and hearing protection strategies for power cutting environments. Effective controls protect health and maintain visibility.

Lesson 3 • Angle Grinder Cutting Applications

Addresses disc selection, guard positioning, and controlled cutting strokes with angle grinders. Proper technique prevents disc fracture and workpiece overheating.

Lesson 4 • Jigsaw and Reciprocating Saw Techniques

Teaches blade selection, orbital settings, and curve-cutting strategies for jigsaws and reciprocating saws. These tools enable internal and irregular cuts impossible with circular saws.

Lesson 1 • Table Saw Fundamentals

Covers blade height, fence alignment, splitter use, and push-stick technique for table saws. Correct setup is the primary defense against kickback injuries.

Lesson 2 • Machine Maintenance and Calibration

Covers blade changes, fence squaring, and lubrication schedules for stationary cutting machines. Regular calibration maintains accuracy and extends machine service life.

Lesson 3 • Scroll Saw and Detail Cutting

Introduces blade threading, tension adjustment, and feed control for intricate interior cuts on scroll saws. Fine blade control produces complex profiles without breakout.

Lesson 4 • Band Saw Setup and Operation

Teaches blade tensioning, guide adjustment, and feed pressure for band saws. Proper blade tracking enables accurate resawing and curved cuts.

Lesson 1 • Kerf Management and Material Allowance

Explains kerf width, blade set, and material allowance planning to achieve net dimensions. Accounting for kerf prevents undersized parts and material waste.

Lesson 2 • Quality Inspection of Cut Parts

Introduces go/no-go gauges, surface inspection, and dimensional verification methods. Systematic inspection catches defects before parts enter assembly.

Lesson 3 • Compound and Angled Cuts

Covers trigonometric layout, bevel calculations, and machine setup for compound angles. Mastery enables accurate joinery and complex geometric profiles.

Lesson 4 • Jig and Template Design

Teaches construction of cutting jigs and templates that guide tools along precise paths. Jigs eliminate layout repetition and reduce operator error on production runs.

Lesson 1 • Laser Cutting Parameters

Teaches power, speed, focus, and assist-gas settings for laser cutting thin to medium stock. Parameter optimization balances cut speed with edge quality and kerf width.

Lesson 2 • Waterjet Cutting Fundamentals

Introduces abrasive waterjet mechanics, pressure settings, and material suitability for cold cutting. Waterjet eliminates heat-affected zones and suits heat-sensitive materials.

Lesson 3 • Thermal Cutting Principles

Explains the physics of flame, plasma, and laser cutting including heat-affected zones and oxidation. Process selection depends on material type and required edge quality.

Lesson 4 • Post-Process Edge Treatment

Covers deburring, slag removal, and edge finishing methods following thermal and abrasive cutting. Clean edges are required for safe handling, coating adhesion, and assembly fit.

Lesson 1 • Automated System Monitoring and Troubleshooting

Covers alarm interpretation, sensor diagnostics, and corrective actions for CNC cutting system faults. Rapid fault resolution minimizes downtime in production environments.

Lesson 2 • CNC Machine Setup and Homing

Covers machine homing, work coordinate system setup, and tool length measurement for CNC cutting machines. Correct setup prevents crashes and ensures part accuracy.

Lesson 3 • Toolpath Optimization Strategies

Teaches lead-in/lead-out design, tab placement, and nesting to maximize material use and cut quality. Optimized toolpaths reduce cycle time and minimize scrap.

Lesson 4 • CNC Program Editing and Verification

Introduces G-code structure, block editing, and simulation tools for verifying CNC cutting programs. Simulation catches collisions and errors before machine execution.

Lesson 1 • Cut-List Planning and Scheduling

Teaches cut-list creation, material yield calculation, and job sequencing for production environments. Effective planning reduces material cost and machine idle time.

Lesson 2 • Tooling Cost and Life Management

Covers tool life models, replacement triggers, and cost-per-cut calculations for production cutting. Managing tooling cost directly impacts profitability of cutting operations.

Lesson 3 • Lean Principles in Cutting Operations

Applies value stream mapping, 5S, and waste elimination to cutting workflows. Lean methods expose non-value-adding steps and reduce overall lead time.

Lesson 4 • Continuous Improvement and Root Cause Analysis

Applies PDCA cycles, fishbone diagrams, and 5-Why analysis to recurring cutting defects. Structured problem-solving prevents defect recurrence and builds process knowledge.
