A force torsor analysis for a turning process in the presence of self-excited vibrations

TL;DR

This paper introduces a novel force torsor analysis method for turning processes experiencing self-excited vibrations, using a six-component dynamometer to measure complete torque during cutting.

Contribution

It presents the first comprehensive analysis of forces and moments in turning with self-excited vibrations across various cutting parameters.

Findings

Force and moment variations depend on depth of cut and feed rate.

The analysis provides detailed insights into the torsor during vibratory turning.

Experimental setup successfully captures complete torque data.

Abstract

A testing device in turning including, in particular, a six-component dynamometer, is used to measure the complete torque of the cutting actions, in a case of self-excited vibrations. For the tests, the used tool was a noncoated carbide tool (TNMA 160412) without chip breaker. The cutting material is a chrome molybdenum alloy type (ASI 4140). The cylindrical test tubes have a diameter of 120 mm and a length of 30 mm. For the first time, we present an analysis of forces and moments for different depths of cut and different feed rates.
