The article presents the result of research in the field of processing wooden railroad ties and thermoplastic polymer household waste with obtaining composite railroad ties under conditions of energy efficiency of technological processes. The wood of the used wooden ties contains a significant proportion of chemical compounds based on creosote. As a result of the thermal and mechanical action, the creosote compounds in the wood form hydrophobic surfaces, thereby fulfilling the function of the bonding additives. Under the above-mentioned conditions, hydrogen bonds are formed between the components of the wood composite, that, in its turn, allows achieving the task of creating a functional composite, which varies in the compound of elements and the modes of production processes. Experimental studies were held on the nature of justification and correction of theoretical studies. The experimental stand of composite production is realized on the principle of energy efficient cooling cycles of the obtained composite with heat transfer for heating the initial components. The obtained results of experimental studies exceed the regulation values by every measure. The comparison justifies the quality of the experimental samples obtained with respect to these values.

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.
