Modeling and verification of cutting tool temperatures in rotary tool turning of hardened steel

Abstract

This paper addresses modeling of the tool temperature distribution in self-propelled rotary tool (SPRT) machining of hardened steels. Since tool life is significantly influenced by cutting temperatures, a model is developed to analyze the heat transfer and temperature distribution in rotary tool turning of hardened 52100 steel (58 HRC). The model is based on the moving heat source theory of conduction and employs the finite element method (FEM) for its solution. The model is experimentally verified through measurements of the cutting tool temperature distribution using an infrared camera under different cutting conditions. Finally, both rotary and equivalent fixed tool cutting processes are compared in terms of cutting tool temperatures generated. #

Machining of Hard Materials – Definitions and Industrial Applications

“…The continuous spinning of the cutting insert about its axis in addition to the main cutting and feed motions is the major difference between rotary cutting and conventional cutting [47][48][49]. Figure 1.21 shows the principle of such a tool.…”

Cutting Mechanics of Turning with Actively Driven Rotary Tool

“…The rotary cutting tool (1) has received a considerable attention from many researches during past decades (2)- (8) due to its application in the machining process is possible to decrease the cutting temperature as well as to increase the machining productivity. As the cutting tool rotates and it is cooled during the non-cutting period in one rotation of the tool, it is expected that the temperature of the tool decreases compared with conventional turning.…”

Tools with rotary cutting edges – classification and terminology

“…W ostatnich latach w wiodących technologicznie krajach z sukcesem wraca się do koncepcji obróbki narzędziami ze zmienną czynną krawędzią skrawającą, zwłaszcza w zakresie obróbki materiałów trudnoobrabialnych [1][2][3][4]. W przypadku procesów obróbki takich materiałów za pomocą tradycyjnych metod napotyka się bowiem wiele trudności.…”

“…Zaproponowano więc, jako efekt badań własnych [1,2], studium literatury przedmiotu i patentów [3][4][5][6][7][8][9] oraz wprowadzenie systematyki w dziedzinie konstrukcji tych narzędzi i ich zastosowań. Wydaje się to uzasadnione również w kontekście ich historycznego rozwoju.…”
