Mazurchuk S. Means of improving production technology of oak timber pieces

Dissertation work is dedicated to the solution of important research and practical task – the rational use of raw material in the production of logging of the set specification considering the thermal non-destructive method of control and prognostication of their useful and quality output depending on measuring-quality description of raw material and products. Dependences of useful and quality output of logging were received on the parameters of measuring-quality description of raw material and sawed products and coefficients of grade of saw-timbers and logging that can be used for the effective planning of production. The simulation of program modeling is developed of logs cutting and saw-timbers for logging, that allows to fold the charts of plan taking into account measuring-quality description of raw material and products. Possibility and expediency of application of thermal non-destructive method of control are set for identification of basic sort forming defects of woods in the saw-timbers of oak. The basic parameters (temperature of thermal stimulation, duration of thermal stimulation, temperature of reflection of sort forming defects) of process of identification by the thermal method control of basic sort forming defects of oak (rot, twigs, cracks) were defined in sawtimbers. A method and line of thermal non-destructive exposure of sort forming defects of wood are developed and offered in the saw-timbers of initial humidity. The way of control of identification process of wood defects was developed for the offered method and line. Recommendations for logging producers from wood of oak are worked out that are implemented at three enterprises, that help to reduce the material consumption of production.
