INCREASE PRODUCTIVITY OF HARD-TO-MACHINE MATERIALS BY PREVENTIVE HEATING OF THE WORKPIECE

The possibility of increasing productivity by increasing the cutting parameters of difficult-to-machine materials, using expensive tool materials, etc. is an extensive trend of innovative improvement and is accompanied by high costs of operations and the need to provide expensive equipment. The article argues that a more effective method of improving machining operations is the use of the workpiece Turning with Preventive Heating (TPH) method.

ANALYSIS OF THERMODYNAMIC, STRESS-STRAIN, AND LOADED STATES OF CHROMIUM-NICKEL ALLOY WORKPIECES USING MACHINING PROCESS SIMULATION IN ADVANTAGE SOFTWARE

Machining difficult-to-cut materials, which include most high-alloy chromium-nickel steels and alloys, requires optimization of cutting parameters, correct application of tool materials, cutting blade geometry, etc. The particular relevance of a scientifically based analysis in addressing these issues is due to the large costs incurred in machining products made from such materials. The possibilities of experimental research to provide correct technological recommendations are quite limited.

Investigation of the Influence of Machining Factors on the Workpiece Deformation Mode in the Chip-forming Zone by the Finite Element Method

The results of studies of the impact strength, temperature factors and parameters of cutting tool geometry on the formation of the stress-strain and thermodynamic state of surfaces with different types of engineering materials in the cutting process are described in the article. Analysis of simulation modeling of power, temperature and deformation parameters is the basis for making of forecasting models of influence of the structure and process parameters on the formation of complex operational properties of the product.
