Wood Processing course

Lesson 1 • Overview of the Wood Processing Industry

Maps the full supply chain from forest to finished product. Contextualises each processing stage within commercial and environmental frameworks.

Lesson 2 • Wood Defects and Grading Basics

Identifies natural and processing-induced defects that affect material value and usability. Introduces grading systems used to classify lumber quality.

Lesson 3 • Workplace Safety Fundamentals

Introduces hazard identification, personal protective equipment, and emergency procedures specific to wood processing environments.

Lesson 1 • Debarking and Log Preparation

Explains debarking methods and pre-processing steps that protect downstream equipment. Proper preparation reduces blade wear and contamination.

Lesson 2 • Headrig and Primary Sawing

Teaches band saw and circular headrig operation for initial log breakdown. Sawing patterns directly determine lumber recovery and product mix.

Lesson 3 • Lumber Recovery and Yield Analysis

Introduces methods for measuring and improving lumber recovery from logs. Yield analysis drives continuous improvement in primary processing operations.

Lesson 4 • Log Yard Operations

Covers log receiving, sorting, storage, and inventory management. Efficient yard operations directly reduce raw material waste and processing delays.

Lesson 1 • Moisture Content and Wood Movement

Explains how moisture affects wood dimensions, strength, and workability. Understanding wood-water relationships is essential before applying any drying method.

Lesson 2 • Kiln Drying Principles and Schedules

Teaches conventional kiln operation, schedule selection, and psychrometric control. Kiln drying achieves precise moisture targets required for secondary processing.

Lesson 3 • Air Drying Methods

Covers stacking, stickering, and site selection for outdoor and shed drying. Air drying is the lowest-cost first stage before kiln processing.

Lesson 4 • Drying Defects and Remediation

Identifies casehardening, honeycombing, collapse, and surface checking caused by improper drying. Remediation techniques restore value and prevent further degrade.

Lesson 1 • Sanding and Surface Preparation

Covers belt, drum, and wide-belt sander operation for final surface preparation. Correct grit progression and pressure settings determine coating adhesion quality.

Lesson 2 • Cutting Tool Theory and Geometry

Explains rake angle, clearance angle, and chip formation in wood cutting. Tool geometry knowledge underpins correct setup for all machining operations.

Lesson 3 • Routing, Boring, and Tenoning

Introduces router, boring machine, and tenoner operations for joinery and component production. These operations require precise depth and speed settings to avoid tearout.

Lesson 4 • Planing and Moulding Operations

Teaches surfacer, planer-moulder, and profile cutter setup for dimensioned and shaped products. Correct feed rate and knife projection control surface quality.

Lesson 1 • Panel Finishing and Quality Control

Covers sanding, trimming, and surface treatment of panels before shipment. Quality control tests verify dimensional tolerance, bond strength, and emission compliance.

Lesson 2 • Medium-Density Fibreboard Production

Covers fibre refining, blowline resin application, mat forming, and pressing for MDF. Fibre quality and moisture uniformity are critical to surface smoothness and machinability.

Lesson 3 • Oriented Strand Board Production

Teaches strand geometry, orientation, and pressing for structural OSB panels. Strand alignment and resin distribution determine bending strength and moisture resistance.

Lesson 4 • Plywood Production Process

Covers veneer peeling, drying, gluing, and hot-press operation for structural and decorative plywood. Veneer quality and lay-up sequence determine panel strength and appearance.

Lesson 1 • Pressure Treatment Processes

Covers full-cell and empty-cell pressure impregnation cycles used in industrial treatment plants. Process parameters determine preservative distribution and retention in treated timber.

Lesson 2 • Wood Degradation Mechanisms

Identifies fungi, insects, marine borers, and weathering as primary degradation agents. Understanding attack mechanisms guides treatment selection and retention requirements.

Lesson 3 • Non-Pressure and Surface Treatments

Introduces dipping, brushing, spraying, and diffusion methods for lower-hazard applications. These methods suit on-site remedial treatment and species with limited treatability.

Lesson 4 • Environmental and Safety Compliance

Addresses worker exposure controls, effluent management, and end-of-life disposal for treated wood. Compliance with environmental regulations protects workers and surrounding ecosystems.

Lesson 1 • Lumber Grading Standards and Rules

Teaches visual and machine stress-rated grading methods for structural and appearance lumber. Correct grading ensures products meet end-use performance and market requirements.

Lesson 2 • Statistical Process Control in Sawmilling

Applies control charts and process capability analysis to sawing and drying operations. SPC identifies variation sources before they produce out-of-specification product.

Lesson 3 • Dimensional Measurement and Tolerances

Covers precision measurement tools and tolerance standards for sawn and machined lumber. Dimensional accuracy directly affects product fit, customer satisfaction, and waste reduction.

Lesson 4 • Panel Product Testing and Standards

Covers mechanical, physical, and emission tests required for panel product certification. Test results verify compliance with performance standards used in construction and furniture markets.

Lesson 1 • Residue Management and Circular Economy

Covers sawdust, bark, chips, and trim utilisation strategies to maximise value from all wood fractions. Residue valorisation reduces disposal costs and supports circular economy goals.

Lesson 2 • Energy Management and Efficiency

Analyses energy consumption in drying, pressing, and machining operations and identifies reduction opportunities. Energy efficiency lowers operating costs and reduces the carbon footprint of production.

Lesson 3 • Equipment Maintenance and Reliability

Introduces preventive, predictive, and total productive maintenance strategies for processing equipment. Maintenance programmes reduce unplanned downtime and extend equipment service life.

Lesson 4 • Production Planning Fundamentals

Covers demand forecasting, production scheduling, and capacity planning for sawmill and panel operations. Effective planning aligns raw material supply with market demand and equipment capacity.
