Cubature of the rounded log

Cubature of the rounded log – wood-cylindered logs laid extremely tight, with minimal gaps. The magnitude of the gaps is defined by the current standards for the forest harvesting.

What to know the cube?

Rounded log – normal rounding, with one side of which the wood layer is removed. Compared to a simple rounded – product with a longitudinal neck, the form of which repeats the arc of the circle. Thanks to this, the log cabin is reliable, steadily fixed on each other, stacked in the perfect vertical wall.

Cubature of the rounded log – the value of the target volume, but devoid of constant mass.

This is the main value used for mutual settlements with the organization or company selling the forest (log) at a certain price. Cost cubic meter log, despite the similarity on the material, varies, for example, with a cubic meter of a conventional board. To get more wood (according to cubic meters), it carefully dried.

How to calculate on the table?

Before counting on the table, how much is the “cube” of the logs, clarify the breed, the variety and degree of drying of the tree. The raw log wrestle is heavier than dry – the percentage of water, driving it, can reach 50% by weight. It makes wood more dense and hard. For simplicity of calculation, the most frequently found logs of logs (in length, diameter and surface area / section) are up to several dozen values. Cubature of OCB for 6 meter logs is given in the table.

Before ordering rounded logs, the owner of the future facility is calculated, how many rounds will need for the future construction. It is advisable to order exactly so many copies as much as enough to build walls with door and window openings.

Calculation of the formula

Formular calculation is used mainly for the triggered. The bark is removed from them, then they are pulled out on the sawmaker or industrial fresher to the perfect round state. Next, from the processed (calibrated) log is cut in the form of a “crescent” layer that is responsible for the correct vertical laying of briced on each other.

The standard of the length of the cylindered log is adopted by 6-meter length. Segments in 3, 4, 5 m will be noticeable lower, and the purchase of a log will become economically unprofitable.

Brica more than 6 m in length is also not much more profitable in terms of price / extension.

The rounded log has a strictly agreed. Length and log radius are taken into account. The volume occupied by the log is equal to the product of the number 3,1415926535 … (approximate – 3,1416), the square of the radius value to the length of the instance. The formula does not fully take into account the volume of wood cut in the form of a crescent – it is advisable to calculate it separately, and deduct from the value. For example, a log in diameter 220 mm (length in 6 m) is among the number of more than 4 pieces – for each cubic meter.

Purchased a calibrated log without a cropped layer having identical to one instance to other values, a certain value of the volume will change to the number of such logs. Oval section of the unprocessed (neocular to the perfect state on the log cabin) prompts the estimator that you need to add more and smaller diameters, and the resulting number is divided into two. The average value will give an approximate rating of the radius – here are not taken into account the irregularities of the barrel from which the bark was removed.

The big batch of logs does not provide for the exact calculation of the volume occupied by each log. If the user is ready to overpay, it will acquire a calibrated (sharpened to perfect rounding) log.

The cost of the work includes the work of industrial milling or sawmills, control of the working and operator and the cost of wear cutting equipment. As a result, the Customer will receive perfectly processed brices – in the requested number of pieces – where the errors of measurements and calculations are almost excluded.

Data on the number of logs of the chosen “caliber” in one cubic meter are calculated theoretically and confirmed by the results of inventive tests. Breed irregularity can not guarantee a high grade of the calculation of the forest cube.
