Sažetak
The article presents the simulation model for simulated measurement of unedged sawn boards with the help of CAD and spreadsheet program. The simulation model is based on graphical simulation of s awing in CAD program on cross sectional area of simulated logs. The cross section of log in simulation can be circular or elliptical and diameter of simulated log can be in the range from 20 cm to 100 cm. From the cross section of each unedged sawn board t hat is obtained by simulated sawing, the width can be easily measured in different ways that are common in sawmilling practice and are prescribed by national norms in Croatia. Because different measurement methods can yield different volumes of boards, it is of interest to determine if there is any unfair advantage in using different methods for width measurement of the same unedged sawn board. After the widths have been measured on the simulated boards, they are further processed in a spreadsheet program a nd the results of simulated measurements with different measurement methods can be easily compared and used for comparison with data obtained from measurements on real boards in regular sawmilling practice. The presented simulation model is practical becau se it represents quick, simple and cheap way for comparing influence of different width measurements methods on board volume calculation. The disadvantage is that drawn models are idealized i.e. not accurately depict the actual form of logs, and finally th e actual widths of boards.
