Abstract

Currently, energy and resource conservation is one of the most urgent tasks for production. One of the ways to solve this problem is the establishment of rational modes of wood and wood materials mechanical processing, ensuring the required quality of processing with minimal energy costs. Laminated chipboards are widely used in the furniture industry. Milling the edges of this material is a rather energy-intensive process and reducing energy costs is an important task both from a scientific and practical point of view. One of the ways to reduce energy consumption and improve the processing quality is to create an inclination angle of cutting elements. The article presents the experimental studies data of the technological modes influence on the energy intensity of the laminated chipboard milling process. In contrast to the power consumption, the specific cutting work is the more objective characteristic of the process energy intensity and represents the work consumption on removing a unit of chip volume. A distinctive feature of this study is consider not only the generally accepted technological factors affecting the energy intensity of the milling process, such as the cutting angle, cutting speed, height of the removed layer, chip thickness, but also the inclination angle of the knives cutting edge. Graphical dependencies that allow visual assess the impact of each technological factor on the energy intensity of the milling process are constructed. It is established that the creation of the inclination angle of the cutting edge in the range from 0 to 30 reduces the energy intensity of the process by up to 54%.
