FORECASTING THE LEVEL OF PARASITIC VIBRATIONS OF THE MILLING SYSTEM IN THE CUTTING ZONE THROUGH ANALYSIS OF NOISE ACTIVITY
Annotation
Experimental data on acoustic characteristics of the working area of cutting equipment in the idle mode are analyzed. Parameters are determined that affect the frequency characteristics of the active system recognized by the value of the error in relative position of groups of elements. Relationship between of the rotary milling system runout in the absence of applied load and the noise level recorded by sound analyzers is established. A method is proposed for predicting the level of vibrational activity of a milling system in the cutting zone that occurs during the finishing of hard-to-work materials.
