DETERMINATION OF FACE MILLING RATIONAL MODES BASED ON SHOCK-VIBRATION EFFECT REDUCTION

Abstract

The purpose of the article is to develop a method for determining the optimal machining modes of milling machines by estimating the vibration level and initial contact of a cutter tooth and a workpiece. The work is based on the use of experimental data obtained by measuring vibration characteristics, which serve the basis for determining the optimal milling modes of the end mill with a hexagonal plate. The experiment results in the development of a methodology for determining optimal milling modes (based on the obtained experimental data of the vibration level), and identification of the relationship between the initial contact line of the cutter tooth and the workpiece by means of a 3D model. The methodology of determining the optimal milling modes is developed on the basis of the experimental data of the vibration level. Based on the results of the conducted studies, the recommendations are given on setting the optimal processing modes for a cutter with a hexagonal plate taking into account the comparison of the obtained RMS values of the vibration velocity and General technical standards of permissible values of the overall vibration level. The relationship is revealed between the line of initial contact of the cutter tooth and the workpiece by means of a 3D model and the level of vibration.
