- W4380592009 abstract "Purpose. To solve a scientific and technical problem related to the technological support of high-performance machining of a cast iron part by optimizing and controlling its machinability with a hard-alloy tool on multi-axis CNC machines using CAD-CAM systems. The methods. The methodological basis of the work is a systematic approach and analysis of the study of the object of research, based on the use of: numerical and graphical-analytical research methods in order to establish a systematic relationship between turning parameters and the properties of the material being processed, tool geometry and its stability, parameters of cutting modes with the corresponding indication in the control program for the CNC machine. Findings. Numerical research results have been obtained for a scientifically based approach to solving the technical problem of high-performance turning of cast iron parts on multi-axis machining centers, which contains a set of adjusted methods and algorithms for predicting their machinability with ensuring the reliability of hard alloy cutting tools. The results obtained were compared with known works related to the study of machining processes of various grades of steels, alloys, and cast irons, the assessment of the reliability of cutting tools, the accuracy and roughness of the machined surface, and the results of measurements of cutting force parameters. The maximum relative error of the calculations did not exceed 6-8%. The originality. Establishment of a complete and systematic connection of machining parameters with the properties of the processed material, tool geometry and design and technological factors of the part for the calculation of an optimized automated production technology. In the mathematical and statistical processing of experimental data, which made it possible for the first time to obtain complex dependencies in a form convenient for calculation and analysis, which give a clear picture of the effect of each parameter of the turning process on its energy and time indicators when compiling a rational technology for machining a part of complex geometric shape in a CAM system. Practical implementation. It consists in selecting and justifying the optimal geometric parameters of cutting tools and equipment, establishing the nature of the influence of the conditions of turning cast iron on the main process parameters - machining time and operating parameters depending on the hardness of the part material and tool material. Practical recommendations are given on the optimal use of CAD-CAM systems, adjustment of process results and operating parameters to obtain optimal results at the stage of production preparation." @default.
