If there are no problems with the determination of weight and volume, for example, when buying liquids or bulk materials, then everything is different with timber. Here, the system for determining the volume of the required amount of this raw material raises many questions, since no one wants to pay extra money.
It turns out that not all buyers know how many types of wood actually exist. But it differs from each other in the degree of processing, type, grade, which directly affects its cost. This is how the slab volume is calculated - a very popular type of lumber.
First, the measured batch of business slab should be sorted into 2 groups. One group consists of boards with a length of more than 2 m, the other - less than 2 m. Stacking in a pile is made with thick and thin ends alternately in different directions, while the surface of the slab remains at the bottom and top. The stack must be compact and tight at right angles and the same height.
Next, you should multiply the average height of the stack by the width and length, and as a result, the fold volume is determined.
The volume of softwood and hardwood lumber can be determined in two ways. The first method involves measuring each bar or board, and then the volume, after which the results are summed up.
The second method is with the help of a cubature, a special table designed to determine the volume of such sawn timber. The measurement of boards related to unedged sawn timber is made in a slightly different way. In this case, the width of one-sided edged and unedged boards is calculated as half the sum of the upper and lower planes.
Of course, it is worth dwelling separately on the measurement of the volume of round timber. Here you have to measure each log separately - the length and width of the upper and lower ends. Special tables, according to which these calculations are made, are called cubatures, which were discussed above.
After the volume of each log has been measured separately, the addition is performed, and the total cubic capacity is obtained. A corresponding computer program already exists.
