“…The thermocouple was placed into a hole drilled from underside of the tool which through the tip goes out to the face surface at 0.6 mm far from the cutting edge. The hole accommodates the thermocouple S-type (Pt + 10% Rh) with wire diameters 0.05 mm [18].…”

Original scientific paper https://doi.org/10.2298/TSCI170518197NThe aim of this work is to explore the possibilities of the implementation of systems based on a thermoelectric module for cooling the cutting tool. This cooling becomes significant when it is not possible to use conventional coolants and lubricants. Starting from existing mathematical models for the calculation of the temperature field of the cutting tool, a mathematical model is developed that takes into account the cooling based on the thermoelectric module. The use of the finite element method determines temperature field when dry lathe machining in the cooling conditions based on the thermoelectric module. The Software package, PAK-T, is used for the calculations and was developed at the Department of Applied Mechanics, Faculty of Engineering in Kragujevac, Serbia. The system for cooling the cutting tool based on the thermoelectric module was realized under laboratory conditions on a prototype model, which consists of a cutting tool and a thermoelectric module. Verification of the obtained results was carried out on the basis of a mathematical model by experimental research of the temperature field of the cutting tool in terms of cooling based on a thermoelectric module.

“…The aim of this heading is to attempt a review of the contents of those works and consequently their comprehensive application. Nedic & Eric (2014) worked on temperature measurement technique known as tool-work thermocouple. This method is based on the principle that two metals, when they are in contact, produce a small amount of voltage which is proportional to temperature variation.…”

“…According to Nedic & Eric (2014), metal cutting temperature was measured with artificial thermocouple and metal machine-ability was analyzed from aspect of cutting temperature. In Sui et al (2012), LM35 and PIC16F873 microcontroller was used to build a device which can measure safely the indoor temperature in firm buildings such as greenhouses, warehouses or silos.…”

This paper presents a simple temperature measurement design using thermistor for industrial purposes. This paper establishes the characteristics of the resistance via temperature and it's constant since it has been difficult to determine if a thermistor has a positive or negative temperature coefficient. The practical approach was adopted to determine its characteristics where it was revealed that all thermistors are nonlinear in nature. In this design, the empirical and the practical design were compared; its implementation considers the temperature within the ranges of 35 0 C to 60 0 C which is 308K to 333K respectively. Other considerations were given to the output voltages between 0.155V -1.055V, ambient temperature of 0 0 C -25 0 C, Percentage non-linearity as low as 0.16, and a sensitivity of 0.0367V/ºC but the resolution of this device is 1ºC.The result obtained were analysed to ascertain the functionality of the experimented design via its performance and suggestions on further improvement were made.

“…They concluded that if the tool's temperature is increased that leads to the acceleration of the wearing process. The high cost of specific cutting tools materials and the cost of downtime for tool changing must be minimized [7]. Tool wear plays a key role in the economy of machining operations.…”

In this study, cutting tool`s wear, temperature and forces during turning process were investigated. Used were two types of inserts HM and CBN were taken as cutting tools and round bar of EN 90MnCrV8 hardened steel was used as the workpiece. Since the life of the cutting tool material strongly depends upon cutting temperature, it is important to predict wear and heat generation in the tool. Determination of temperature field in tool was by thermal camera. Determined was dependence of temperature tool wear parameter for two cutting tool materials as well.
