The loads acting on a workpiece during machining processes determine the modification of the surface of the final workpiece and, thus, its functional properties. In this work, a method that uses thermocouples to measure the temperature in precision fly-cutting machining with high spatial and temporal resolution is presented. Experiments were conducted for various materials and machining parameters. We compare experimental measurement data with results from modern and advanced machining process simulation and find a good match between experimental and simulation results. Therefore, the simulation is validated by experimental data and can be used to calculate realistic internal loads of machining processes.

The purpose of this work is to justify the need to develop a set of solutions for the organization of the step-by-step planning of rational use of disturbed lands. Currently, environmental problems have worsened due to the closure of mining enterprises, which has led to an urgent need for a scientific approach to the environmental remediation of mining regions and their future rational use and evaluation. The implementation of such approaches can be largely achieved through the creation of improved natural and anthropogenic landscapes on disturbed lands. As a result of the research, the procedure and sequence for the development of rational use of technologically disturbed lands have been formed. This procedure and stages of work performance will provide an opportunity for their reuse, as well as systematize the activities of local government bodies. The criteria for choosing the direction of the technogenic landscape transformation in Ukraine, which are based on the prevention of undesirable, uncontrollable processes of natural and technogenic origin have been formed. The process of the technogenic landscape transformation should be based on the use of potential opportunities and trends inherent in nature itself. The studies on the rational use of disturbed lands in order to adapt them to reuse and prospective use has shown that lands formed as a result of mining can be used for both recreation and industrial development. Complex schemes of sequential actions in the organization of works on the rational use of lands have been develope.
