Adaptation of the Methodology of Designing Cylindrical Milling Processes to the Profile Milling Processes

The processes of cylindrical and profile milling of wood are considered, it is noted that when designing the technological operations of cylindrical milling, a large theoretical and experimental backlog created by scientists and specialists of woodworking complex enterprises is used. At the same time, profile milling of wood does not have such a knowledge base as cylindrical, it needs an effective technique for designing technology, equipment, cutting tools and automation tools for processing and control processes. It is proposed to use the accumulated knowledge and experience in the field of cylindrical milling in the development of equipment and technology for profile milling of wood, for which an analytical model of the correction coefficient for profile milling was developed and experiments were conducted to justify its adequacy. With the use of high-speed photography, we studied the removal of stocks for cylindrical and profile milling of wood, which resulted in a more significant dispersion of chips in the process of shaped milling, which is reflected in an increase in the power consumption of milling. The use of a correction factor for profile milling allows using the knowledge base created by predecessors in the field of woodworking and adapting a well-known technique to the processes of profile milling of stemwood and large sawmilling wastes.
