Natural and Energy Resource Saving Based on the Development of Technology for Profile Milling of Wood Waste

It is noted that the preservation of forest resources in the conditions of a permanently developing world-wide technological civilization is a major scientific and national economic problem. The results of the analysis of the current state of profile milling of wood and non-technological large sawmill waste are presented, and it is indicated that due attention was not paid to profile milling with a shaped tool. The technology and equipment have been developed with programmed control for the mechanical processing of large wood waste, equipped with an automatic control system for the working feed of a workpiece and having passed certification tests, as well as production approbation. The comparative tests of equipment with an automatic control system are presented, confirming the possibility of increasing the productivity of the profile milling process for workpieces with variable allowance for processing. The proposed equipment and technology allow not only saving material and energy resources in the process of mechanical processing of wood waste in the form of slabs, but also contributing to the preservation of forests due to deeper wood processing.
