“…The use of shaping cutter allows to improve the utilization of the material [19,20], to reduce the waste occurring during milling of products widely used in various industries, including in woodworking [21,22]. In some industries, for example in wood working the recycling is an actual economic problem [23][24][25][26][27][28][29].…”

This paper presents a mathematical model of the maximum thickness and the chip area for the processes of cylindrical and profile milling of various materials, including wood. The analytical dependences connecting the geometry of the shear layer with the elements of the milling mode and cutter design parameters are determined. Also, a model of the volume of material removed from the surface of the workpiece during the milling profile is presented. The comparative calculations of the previously known models and the models developed by the author were done. It was found that the models of the geometric parameters of cutting layer presented in the article are adequate and can be used to calculate the energy performance of the wood milling process with cylindrical and shaping cutters. These models are suitable for use in the calculations of the processing parameters for a wide range of material: metals, wood, plastic, glass and others.

In some industries, for example in wood working the recycling is an actual economic problem [18][19][20][21][22][23][24]. It is known that in the process of cylindrical and profile milling the cutting force changes periodically from a minimum to a maximum value or vice versa, depending on the selected following and opposite circuit of milling [25][26][27][28].…”

The article establishes the analytical relationships linking the geometric parameters of the shaping cutters. A mathematical model describing the geometrical errors caused by the discrete process of product profile milling with shaping cutters was developed. It was specified based on the model that the distribution of errors on the surface treated with cylindrical and shaping cutters is significantly different. It is found that the errors due to the kinematics of the cylindrical milling process, are constant at value irrespectively of the considered cross section of the cutting tooth, and the errors after the milling significantly differ in the distance function of considered transverse plane from its geometric center. The maximum error occurs in the local longitudinal planes of the product, the profile of which is located at the maximum distance from the mounting technological base of product's surface. The plane of the product, where the maximum geometrical errors are formed during the profile milling is called limiting surface. The design of technological process is performed in the product profile geometry, formed in this plane. The rule of spacious arrangement location of the limiting surface of the product according to its drawing. Using the limiting surface in the design of the operation of profile milling with shaping cutters significantly reduces the duration of the design procedure and eliminates the cost of production on experimental studies related to ensuring the geometric accuracy of products at the initial stage of their production.

“…One of the processing of wood waste is to use them in the production of wood-polymer composites (WPC) [1,2]. For receiving thermal energy and generating gas suitable for the production of chemicals and chemical products wood waste can be processed by the methods of gasification and pyrolysis [3][4][5][6][7].…”

The article describes a new multilayer wood-polymer composite material, the outer layer of which comprises wood flour, polypropylene, polybutadiene, concentrated dye. The inner layer comprises longwise oriented wood particles of the fibrous type of 2-10 mm and the recycled thermoplastic polymer. An experimental complex used to identify structural and operational characteristics of the composite material was presented. The experimental study of the mechanical properties of the product hardness, abrasion, cross-breaking strength were conducted. The results of the tests selected and validated the composite structure.
