本文是金属切割过程热模拟系列文章的第三部分。在第一部分(Komanduri，Hou，《国际机械科学杂志》，2000，42(9)：1715-1752)中，仅由剪切面热源引起的材料和切屑中的温升分布是使用修正的Hahn移动斜带热源解和适当的剪切面像源(Hahn，美国第一届全国应用力学大会论文集1951)。661-6页)。在第二部分(Komanduri，Hou，《国际机械科学杂志》2000，43(1)：57-88)中，仅使用修改的Jaeger移动带(在芯片中)和固定矩形(在工具中)热源解决方案(Jaeger，新南威尔士皇家学会学报，1942；76：203-24；Carlsaw，Jaeger)考虑了仅由刀具-芯片界面处的摩擦热源引起的温升分布。固体中的热传导，牛津，英国：牛津大学出版社，1959)，具有适当的图像源和不均匀的热强度分布。利用由Chao和Trigger首次提出的泛函分析技术，完成了运动带(芯片)和固定矩形热源(工具)刀具-芯片接触界面处温升分布的匹配(汇刊于ASME 1955，75：1107-21)。本文(第三部分)研究了在主剪切带剪切面热源和刀具-切屑界面摩擦热源共同作用下，金属切削过程中的温升分布。基本方法类似于第一部分和第二部分中提出的方法。该模型被应用于两种金属切割情况，即使用Chao和Trigger(汇刊ASME 1955；75：1107-21)的数据在高Peclet数(约5-20)的情况下使用硬质合金刀具对钢的常规加工，以及使用Ueda等人的数据在低Peclet数(约0.5)的情况下使用单晶金刚石超精密加工铝。(CIRP年鉴1998；47(1)：41-4)。分析结果与实验结果吻合较好，从而验证了模型的正确性。利用为解析解开发的相关计算机程序，计算出了材料、切屑和刀具中的温升分布。可以发现，分析方法比使用的数值方法更容易、更快速、更准确(例如，dut，Breyer，International Journal of Production Research 1964：4：91-114；Tay，Stevenson，de Vahl Davis，The Proceages of the Institution of Machine Engineering(London)1974；188：627)。该分析模型还提供了对金属切削热过程的更好的物理理解。(C)2000爱思唯尔科学有限公司。保留所有权利。
This paper is Part III of a 3-part series on the Thermal Modeling of the Metal Cutting Process. In Part I (Komanduri, Hou, International Journal of Mechanical Sciences 2000,42(9):1715-1752), the temperature rise distribution in the workmaterial and the chip due to shear plane heat source alone was presented using modified Hahn's moving oblique band heat source solution with appropriate image sources for the shear plane (Hahn, Proceedings of the First US National Congress of Applied Mechanics 1951. p. 661-6). In Part II (Komanduri, Hou, International Journal of Mechanical Sciences 2000,43(1):57-88), the temperature rise distribution due to the frictional heat source at the tool-chip interface alone is considered using the modified Jaeger's moving-band (in the chip) and stationary rectangular (in the tool) heat source solutions (Jaeger, Proceedings of the Royal Society of New SouthWales, 1942;76:203-24; Carlsaw, Jaeger. Conduction of heat in solids, Oxford, UK: Oxford University Press, 1959) with appropriate image sources and non-uniform distribution of heat intensity. The matching of the temperature rise distribution at the tool-chip contact interface for a moving-band (chip) and a stationary rectangular heat source (tool) was accomplished using functional analysis technique, originally proposed by Chao and Trigger (Transactions of ASME 1955,75:1107-21). This paper (Part III) deals with the temperature rise distribution in metal cutting due to the combined effect of shear plane heat source in the primary shear zone and frictional heat source at the tool-chip interface. The basic approach is similar to that presented in Parts I and II. The model was applied to two cases of metal cutting, namely, conventional machining of steel with a carbide tool at high Peclet numbers ( approximate to 5-20) using data from Chao and Trigger (Transactions of ASME 1955;75:1107-21) and ultraprecision machining of aluminum using a single-crystal diamond at low Peclet numbers ( approximate to 0.5) using data from Ueda et al. (Annals of CIRP1998;47(1):41-4). The analytical results were found to be in good agreement with the experimental results, thus validating the model. Using relevant computer programs developed for the analytical solutions, the computation of the temperature rise distributions in the workmaterial, the chip, and the tool were found. The analytical method mas found to be much easier, faster, and more accurate to use than the numerical methods used (e.g., Dutt, Brewer, International Journal of Production Research 1964:4:91-114; Tay, Stevenson, de Vahl Davis, Proceedings of the Institution of Mechanical Engineers (London) 1974;188:627). The analytical model also provides a better physical understanding of the thermal process in metal cutting. (C) 2000 Elsevier Science Ltd. All rights reserved.
