Machinability investigation of heat-resistant and titanium alloys

• Elementary chip formation in metal cutting

Metal cutting is associated with chip formation. We know that the type of chip depends on the cutting conditions, the tool geometry, and the physicomechanical properties of the blank. If we understand chip formation, we may reduce the energy consumption in machining, increase productivity, extend tool life, and so on.

• Mathematical simulation and optimization of cutting modes in turning of titanium alloy workpieces

Modern machinery production is impossible without data support. Cutting parameters should be optimized for the purpose of increasing effectiveness as well as competitiveness. One of the ways of increasing effectiveness of manufacturing is the application of optimal cutting modes obtained by simulation modeling. The relevance of these cutting modes should be confirmed by a physical experiment. The investigation of cutting process requires considering a great number of factors, taking into account the impact of cutting modes and geometry of a cutting tool on productivity and net cost of machining. From the position of optimization and manufacture intensification, simulation modeling is more multipurpose and less labour-consuming in comparison with the physical experiment.
