Course abstract

One of the task of the study practice is to improve competence about sawmills technologies and equipments by making experimental sawing schedules and producing lumbers as well as assessing quality of lumber according to the quality grades. Other task of the study practice is to visit in the sawmill enterprises and to acquaintance of lumber production technologies by making the analysis of its. View of enterprises promotes a practical understanding of different lumber production technologies and equipment what is used in the lumber production process.

Course Content(Calendar)

1. Calculation and compilation of sawlog sawing schedule, sawlog sawing, sawn timbers measurement and grading (independent works 40 h)
2. Visiting in the sawmills and analysis of production technologies (independent works 40 h)

Requirements for awarding credit points

Laboratory works must be developed, submitted for evaluation and validated.

Description of the organization and tasks of students’ independent work

Dimension measurement, calculation and compilation of sawing schedule and sawing of one sawlog, and measurement of obtained sawn timbers, and analysis of results must be performed by each student in laboratory works. Visiting in sawmills and analyze of their production technologies must be performed by each student in laboratory works. Students submit analyze of production technologies of sawmills only in an electronic form on the website of the e-studies of the Latvia University of Life Sciences and Technologies.

Criteria for Evaluating Learning Outcomes

All tasks and answers to the questions of the leading academic stuff of the laboratory works regarding study plan must be carried. The assessment is based on the number of completed tasks and relevance and answers to questions.
