Abstract

The paper gives characteristic to the operation of width formation of edging sawn timber on the basis of the Ts2D-5A machine. The mechanism of control a mobile saw by the means of manual installation of a hydropositioner on the size of a cutting board across the width is studied. The general methodological regulations on formation of sawn timber sections are formulated; the results analysis of geometry forming of edged sawn timber is done. The article presents a classification of control systems of woodworking machines. The initial technological requirements of position control system for edging machine support from the linear induction motor are developed; changes in the output characteristics of sawn timber depending on the combination of thin and thick board thicknesses are taken into account. It is established that adjustment of stock (secondary element) of the linear induction motor for maximum length corresponds to the smallest width of edging board with allowance for its shrinkage across the nominal width. In this case, imaginary plane parallel to plane of a fixed circular saw of double saw machine and tangent at the points determined by the positions of saw teeth with the controlled broadening on the side is a base surface. Reference position of the nominal width of edged board is a plane parallel to the base surface and spaced away from it by the nominal width of the board with allowance for shrinkage.
