DEVELOPMENT OF BORING CUTTER ADJUSTMENT SYSTEM USING PIEZO ELEMENTS

Abstract

The paper proposes a methodology for experimental studies of non-stationary dynamic systems LDTW (lathe-device-tool-workpiece), in particular, the control of parameter variability, increasing accuracy for measuring increments of recorded values, the predominant importance of recording equipment, the use of narrowband analyzers in measuring modulated oscillations, etc. A significant increase in the accuracy of metal-cutting machines has been achieved on the basis of experimental studies of non-stationary technological systems with variable parameters. The quality and accuracy of machining on finishing and boring machines are subject to very strict requirements. For example, deviations from roundness should not exceed 1-2.5 microns.

The technique of measuring the actual position of the cutter in the process of boring holes, the schemes of loading of the boring bar at taring and tared graphs at static loading, the technique of deciphering the trajectory of shaping on the basis of the obtained oscillograms are given. Graphs of change in the trajectory of the cutter tip motion are obtained.
