Tools and machines for wood processing

Course developer

Course abstract

The aim of the course is to acquire: Wood processing machines and their principal schematics, structure, properties and usability. Technological solutions and their impact on rational usage of forest resources.

Learning outcomes and their assessment

Knowledge - students know principal construction, main components, methodology of feed speed calculation of various wood processing machines and their characteristic technological solutions in factories.
Skills - students understand impact of different parameters on performance on wood processing machines and causalities, that define technological solutions in manufacturing conditions.
Competencies - students are able to identify different wood processing machines, their parts, cutting tool and parameters. Students are able to individually do necessary calculations for designing of the technological flow.

Knowledge, skills and competencies are assessed in tests and laboratory reports.
