IMPROVING THE WORK EFFICIENCY IN THE WORKSHOPS FOR THE TECHNOLOGICAL EQUIPMENT MANUFACTURE FOR PROCUREMENT PRODUCTION

Abstract

Purpose. The work purpose is to increase the efficiency in the manufacturing technological equipment shops for pro-curement and stamping production on the basis of creating an optimal process of reconfiguration of equipment when changing the range of machined parts of equipment. Methodology. Cluster analysis, as a way of grouping multidimen-sional objects, is based on the presentation of the results of individual observations by points in the required geometric space. Logical connections between technical-technological and constructive signs of details and requirements to adjustment of the machine. Findings. The classifier presence of manufactured products allows to determine the typical values of the tool output required for the product elements processing. By unifying the value of the end tool departure in accordance with the typical values of the workpiece height, it is possible to eliminate the need to change the tool setting composition when switching to a new planning unit and the task of the tool production time correcting. The smaller the unique range of tools, the faster production can be rebuilt for a new order. Originality. The introduction into the functional dependence of the end mill cutter on its geometrical parameters - the ratio of the departure length to the length of the cutting part from 0.1 to 0.5 to take into account the influence of cross-section inhomogeneity is substantiated. Practical value. Having an idea of the parts design and technological features, they can be grouped by the homogeneity of the features by cluster analysis to achieve a minimum of readjustment. Conclusions. Logical connections between technical-technological and structural details features and requirements to machine tool adjustment which allowed to present a method of planning units grouping on technical-technological features commonality, such as necessary equipment, devices and tools, by means of cluster analysis for reducing the transition time to a new product and, consequently, downtime. The equation for determining the end mill cutter in the tangential cutting force direction has been modified taking into account the cross section inhomogeneity, tool geometry, and machine rigidity, which allows to unify the tool setting for the end tool departure by determining the footprint and error the machined contour.
