Cutting Mechanics of Turning with Actively Driven Rotary Tool

Abstract

In this paper, turning with actively driven rotary tool method was investigated. The main purpose of the present work is to examine influences of machining conditions especially the tool rotational speed and direction upon the cutting force components, the chip formation and the cutting temperature. Experimental results show that cutting temperature decreases with an increase in the tool rotational speed in a certain speed range. The change in tangential force against the tool rotational speed is not so large than radial and axial force. Increase in the tool rotation in CCW direction exited chatter due to the large radial force.

Characterization of Cutting Temperature and Ignition Phenomena of Magnesium Chip Using Infrared Imaging

“…One method to reduce cutting temperature and to increase the productivity of machining is to use a rotating cutting tool in cutting lathe machining process [2]. Figure 1 illustrates the principle of this machining process.…”

“…Fig. 2 Heat flow along machining lathe process using rotary cutting tool [2] Infrared Imaging Equipment used for the analysis of infrared imaging in general consists of two forms. Radiometry equipment first form is used for temperature measurement precision, and that the two so-called monitoring equipment, which is not designed for quantitative measurements but only for qualitative comparison.…”
