Zhovtobryukh V. Improving the efficiency of machining de-hydraulic hoists by choosing rational parameters of operations by cost

3. Advanced technological processes machining hydraulic systems research objective: reducing costs and improving productivity machining hydraulic systems through the use of advanced design tools and best cutting conditions, me-thods and equipment: fundamental assumptions of engineering technology, the theory of cutting materials, strength of materials, physics , mathematical analysis, mathematical modeling, profiler, roughness, hardness tester, microscope, theoretically the conditions for reducing costs and increasing productivity machining hydraulic systems through the use of modular carbide tools with wear-resistant coating, and the rational choice of cutting devel-HN efficient operations machining hydraulic systems received Further development mathematical model to determine the cost of processing, allowing you to determine the rational cutting and prove the effectiveness of advanced modular carbide tools with wear-resistant coating, which allows for an increase in processing performance more than offset the cost of the instrument and to reduce the cost and complexity of processing; developed a mathematical model for determining the heat balance and temperature encountered when cutting in conditionally shear plane of the material on the front and back surfaces of the blade tool, enabling cost savings to justify the conditions of processing and increase tool life and performance handling, the private joint-stock company "Hydrosila APM" (Kirovograd) and JSC "Dnepropolimermash" (Dnepropetrovsk), mechanical engineering.
