Theory of the Cutter‐Oscillators Design

In this study, a theoretical analysis was conducted on the design of the cutter‐oscillators with a single‐degree‐of‐freedom and a two‐degrees‐of‐freedom, where the resulting direction of deflection of the cutting edge aligns with one of the inertia axes or the direction of action of the cutting force. Designs for cutter‐oscillators and devices for their mounting on a lathe were proposed. These designs allow for the adjustment of stiffness, mass, and natural frequency of the cutter‐oscillator based on the required cutting conditions. A research scheme was presented that enables the recording of the cutting‐edge motion law during turning in the form of oscillograms. The oscillograms allow the study of various types of vibrations (free, free accompanying, forced, and self‐oscillation) that occur during continuous and interrupted turning. The developed designs of cutter‐oscillators facilitate the examination of various vibration process parameters, which can be useful for developing measures to dampen self‐oscillations when machining different materials.
