| Outline and Purpose of the Course | Basic and advanced methods for the measurement, analysis and control techniques required for the research on wood processing are taught through practices. Practices on non-destructive evaluation of physical properties, defects and biodeterioration of wood and wooden structures as well as practices on monitoring of wood processing are involved. | ||
| Course Goals | Students will aim to master the experiment methods necessary to conduct research related to wood processing. | ||
| Schedule and Contents |
1. Processing measurement and assessment (6 sessions) Students will master the methods of measuring and analyzing various types of wood processing by conducting experimental and theoretical examinations of such topics as: measurement and analysis of temperature of cutting tools; evaluation of the finishing surface based on roughness parameters; coating and its evaluation; pattern recognition of cutting and grinding noise; prediction of wood dust concentrations; optimization of tool design using the finite element method; and optimization of wood drying furnaces by solar heat. 2. Wood processing and data processing (6 sessions) Students will master data processing techniques related to wood processing by developing a multimedia-compatible database related to wood processing and applying pattern recognition technology to wood processing. 3. Analysis of physical and mechanical characteristics of wood and wood-based structures (6 sessions) Students will gain proficiency in the finite element analysis of structures by performing an eigenvalue analysis of wooden floor panels and musical instruments using the finite element method and by conducting experimental evaluations of the deformation and vibration of model flooring. At the same time, students will also enhance their understanding of the vibro-acoustic and soundproof characteristics of wood and wood-based structures. 4. Non-destructive testing (6 sessions) Students will enhance their understanding of the non-destructive evaluation of wood and wood-based materials by engaging in experimental and theoretical examinations of topics such as: deformation analysis, visualization of free water movement, and analysis of bonding mechanisms of wood chips using high-resolution X-ray CT scanning; detection of wood-destroying pests such as termites employing acoustic emission and gas sensors; automatic detection of wood pollution using bacteria; and detection of defects in wood using electromagnetic waves. |
||
| Evaluation Methods and Policy | Evaluation will be based on an overall assessment of criteria such as attendance, reports, the quality of presentation, and commitment to projects. | ||
| Course Requirements | General knowledge related to the use, processing, measurement, and control of wood. | ||
| Study outside of Class (preparation and review) | It is desirable that students study the techniques necessary for conducting research related to wood processing independently in their own time by practicing the techniques they have learned through this course. | ||
