Abstract

Wide application of processing multiaxes numerically controlled centres at machine-building enterprises with blank production necessitate the use of new effective milling tools constructions. The purpose of our work was to investigate the influence of the end woodcutting tools at numerically controlled lathes on the vibration degree and surface roughness. Cutting edge inclination ω, teeth number z, circular pitch inequality, chip holding grooves at the tool edges were the variable constructional parameters. During the experiment cutting tools of the same size and type with different constructional elements were used. The experimental installation and data processing techniques have been described. During vibration analysis with Brühll and Kier apparatus average narrow range of mean square values in vibration accelerations was used. Experiment plans and processing procedure of vibroacoustic signals are represented. Linear regressive models based on experimental data allowed estimating the influence of these constructional parameters on processing vibration and surface roughness. There is a steady relation between the vibration level and surface roughness. Such parameters as cutting edge inclination, teeth number, chip holding grooves at the tool edges lessen the processing vibration and enhance the surface quality. Circular pitch inequality influence on these parameters is ambiguous. The authors think that it is necessary to determine spheres of utilization for different cutting tools depending on the timber species, wood materials, and regime parameters
