ANALYSIS TECHNIQUE REFINEMENT OF SPINDLE HEAD VIBRATION OF MILLING AND DRILLING WOODWORKERS

Abstract

Various production methods are realized on the milling and drilling machines. A general approach to the model construction for the vibroacoustic dynamics of the oscillating system “spindle unit — cutting tool” is presented. On the pattern millers, boring and drilling are performed apart from the customary milling. Considering the design features and geometrics of the machining tool, linear and point sources are accepted as an acoustic radiator model. The modal test technology is based on the application of the differential equations of the bending vibrations of the distributed systems and A. N. Krylov’s functions. The analytic dependences for the vibration velocities considering process variables, design features of the tool and spindle units are obtained.
