TEMPERATURE MEASUREMENT OF A CUTTING TOOL IN TURNING PROCESS BY USING TOOL WORK THERMOCOUPLE
Temperature at the cutting point of the tool is a crucial parameter in the control of the machining process. Due to advancement in the machining processes, a special attention has been given on the life of a tool. To achieve this, the best way is to apply the coating to the tool. In this study, coated and uncoated tungsten carbide tools were used and temperature occurred during machining were measured. Among the number of temperature measuring methods, the tool-work thermocouple technique is used as it is easy to install and inexpensive as compared to other methods. The procedure for the working of Tool-work thermocouple and method of calibration is described in this paper.

In many manufacturing processes particularly during metal removing processes, it is sometimes desirable and often necessary to have information on the quantity of heat produced and therefore the increase in temperature and its distribution, heat generated at the tool-workpiece interface during machining is an important factor to solve the metal cutting problems such as dimensional accuracy, the surface integrity and the life of the tool. In the present work, the evolution of the cutting temperature was studied using a combined experimental and numerical approaches; the thermocouple method was used to measure the cutting temperature for turning operations of the steel AISI 1060. 3D cutting model was used to simulate and predict the thermal phenomenon of the heat propagation in the cutting tool, using digital COMSOL simulation software. Based on a comparison between the results of two approaches; numerical and experimental, it was found a correspondence to go up to 96%, taking into ac...

2020
The study presents the influence of the anti-wear coatings and the type of material from which the cutting tools are made of on the cutting temperature occurring on the tool. The cutting tools made of boron nitride and tungsten carbide composite were investigated. The methodology of measuring the cutting temperature using the thermoelement and thermovision techniques was presented. The results of the temperature measurements occurring on the cutting tool in the cutting zone were compared. The paper also presents a method of determining the effective emissivity of the tested tools, necessary for the correct temperature measurement using the non-contact method. The obtained data were interpreted and the relationships described, and then the results obtained were discussed.
Finite Element Analysis on Temperature Distribution of Turning Process
IJMER
ABSTRACT: The aim of this study is to create a finite element analysis simulation model in order to obtain solutions of the cutting forces, specific cutting energy and adequate temperatures occurring at different points through the chip/tool contact region and the coating/substrate boundary for a range of cutting tool materials and defined cutting conditions. Interfacial temperature in machining plays a major role in tool wear and can also result in modifications to the properties of the work piece and tool materials. As there is a general move towards dry machining, for environmental reasons, it is increasingly important to understand how machining temperature are affected by the process variables involved (cutting speed, feed rate, tool geometry, etc.) and by other factors such as tool wear.

In metal cutting process most of heat generated on the cutting tool tip is necessary for the reliable performance of the tool and quality of the finished product. The effect of the cutting temperature, when it is high, is mostly detrimental to both tool and work piece. The machining process and tool life can be improved by the knowledge of cutting temperature and cutting speed. In this paper we have studied the measurement of temperature developed on tool tip during turning operation under different parameter. The metal cutting parameter like, cutting speed, feed rate, depth of cut. in this whole experiment we used k type thermocouple with digital temperature indicator for measuring the various temperature reading during the operation .The tool is used is of high carbon tip, cast iron shank and work piece is used cylindrical aluminum alloy rod. The main reason behind using aluminum alloy is to aluminum alloy has large variety of applications, with light in weight, highly corrosion resistance good electrical and thermal conductivity also good ductility and non magnetic property. In this study Response surface methodology [RSM] is used to analyse machining effect on aluminium material. On the basis of data collected during experiment, we have seen the effect of different cutting parameters on temperature developed on tool tip and suitable turning conditions for obtaining maximum material removal rate at lower temperature. The obtained results are well tabulated and analyzed graphically.

The aim of this study is to check the applicability of various simulation models to obtain finite element solutions of cutting forces, specific cutting energy and adequate temperatures for a range of coated tool materials and defined cutting conditions. Commercial explicit finite element code Thirdwave AdvantEdge has been used in simulations of orthogonal cutting processes performed by means of uncoated carbide and coated tools. The latter were equipped with progressively increasing number of thin layers including TiC, TiN and Al 2 O 3 films deposited onto ISO P20 carbide substrates. Results showing the tool-chip interfacial friction influencing the temperature distribution fields, as the consequence of using coated tools, are the main and novel findings of this paper. The various thermal simulation results obtained were compared with the measurements of cutting temperature and discussed in terms of literature data.

In metal cutting, the temperature measurement of cutting tool is being influenced by cutting factors, especially in continuous cutting operation. Since the life of the cutting tool material strongly depends upon cutting temperature, it is important to predict heat generation in tool with reliable techniques. In this study, cutting tool's average temperature was investigated by placing analog K-type thermocouple sensor in cutting tool. CNMG4325 Grade TN2000 Coated carbide insert with shim has been taken as cutting tool and round bar of EN36 hardened steel as work piece. The Data acquisition has been done with bridging of Amplifier and LabVIEW software through Arduino UNO R3 controller board. According to the mathematical model and equations, generated by CCD based RSM, experiments were performed and cutting temperature was obtained. Results have been analyzed and optimization has been carried out for selecting cutting parameters.
