“…SCM440 steel processing shows the effects of different technological parameters on surface quality and vibration [5,6]. Many studies on milling SCM440 steel aimed to investigate the technological parameters affecting the surface quality as well as the tool life [7,8]. Studies on machining SCM440 steel are mainly applied to cool studies with conventional cooling solutions, showing that cutting fluid benefits temperature reduction and productivity improvement [9,10].…”

With modern production, Minimum Quantity Lubricant (MQL) technology has emerged as an alternative to conventional liquid cooling. The MQLs is an environmentally friendly lubricant method with low cost while meeting the requirements of machining conditions. In this study, the experimental and analytical results show that the obtained acoustic emission (AE) and vibration signal components can effectively monitor various circumstances in the SCM440 steel turning process with MQL, such as surface quality and chip formation as cutting tool conditions. The AE signals showed a significant response to the tool wear processes. In contrast, the vibration signal showed an excellent ability to reflect the surface roughness during turning with MQL. The chip formation process through the cutting mode parameters (cutting speed, feed and depth of cut) was detected through analysis amplitude of the vibration components Ax, Ay and Az and the AE signal. Finally, Gaussian process regression and adaptive neuro-fuzzy inference systems (GPR-ANFIS) algorithms were combined to predict the surface quality and tool wear parameters of the MQL turning process. Tool condition monitoring devices assist the operator in monitoring tool wear and surface quality limits, stopping the machine in case of imminent tool breakage or lower surface quality. With the unique combination of AE and vibration analysis model and the training and testing samples established by the experimental data, the corresponding average prediction accuracy is 97.57 %. The highest prediction error is not more than 3.8 %, with a confidence percentage of 98 %. The proposed model can be used in industry to predict surface roughness and wear of the tools directly during turning

“…The maximum temperature occurs in the proximity of the rake face, yet the difference is that in a knife blade made of HS3-1-2 steel the maximum is moved towards the main cutting edge and is located approximately at the distance of 1/3 rather than in the middle of the length of contact line of the chip with the rake face, and the contact line for an HS3-1-2 steel knife is shorter. While turning at f = 0,3 mm/rev and v c = 25 m/min durability of the cutter edge made of HS3-1-2 steel amounts to T c = 15 min and durability of the cutter edge made of HS6-5-2 steel, to T c = 300 min [24].…”

INVESTIGATION OF CONTACT PHENOMENA IN TURNING USING TOOLS MADE OF LOW-ALLOY HIGH-SPEED STEEL Jan Jaworski, Tomasz TrzepiecińskiOriginal scientific paper In this paper, the results of investigations of the temperature field distribution and tool wearing during C60 steel turning are presented. Abrasive wear resistance tests were carried out for cutters made of low-alloy high-speed steel. Steel samples were heat treated, and then were subjected to ion nitriding, TiN coating, or to complex treatment. The influence of cutting speed on the value of basic parameters characterising the phenomena in the tool-workpiece interface i.e., cutting ratio, friction coefficient, and length of contact zone, is analysed. An increase of the rake angle value causes an increase in the value of the friction coefficient. Furthermore, the value of the friction coefficient decreases as the thickness of the cut layer increases. Investigations of the durability of cutting edges confirm that to define the working conditions of the tool, resistance against hardness loss with increasing temperature at temperatures higher and lower than the tempering temperature is the most significant.

Provedena su ispitivanja otpornosti na abrazivno trošenje tokarskih noževa izrađenih od niskolegiranog brzoreznog čelika. Uzorci čelika su toplinski obrađeni i zatim podvrgnuti ionskom nitriranju, oblaganju TiN ili kompleksnoj obradi. Analiziran je utjecaj brzine rezanja na vrijednost osnovnih parametara karakterističnih za pojave u graničnoj površini alat-obradak, t.j. rezni omjer, faktor trenja i dužina zone dodira. Porast vrijednosti kuta nagiba dovodi do porasta vrijednosti faktora trenja. Nadalje, vrijednost faktora trenja se smanjuje kako raste debljina reznog sloja. Ispitivanja trajnosti rezne oštrice potvrđuju da je u definiranju radnih uvjeta alata, najvažnija otpornost na gubitak tvrdoće kod porasta temperature na temperaturama višim i nižim od temperature popuštanja.

This paper presents the results of investigations of temperature field distribution in the cutting edge and yield strength of tool material for low-alloy high-speed steels. Investigations of temperature distribution in cutting edges were made during C60 steel turning using a semi-natural constantan thermo-element. The obtained results show that the decrease in addition alloy content does not influence the change in thermal-physical properties of lowalloy high-speed steels. Investigations of the durability of cutting edges confirm that to define working conditions of the tool made of high-speed steel, resistance against hardness loss with increasing temperature at temperatures higher and lower than tempering temperature is the most significant. The results of durability investigations of cutters made of HS3-1-2 steel with various kinds of surface treatment confirm the reasons for cutting edge wear of tools made of high-speed steel and ways of the increasing their durability.
