“…With the lubrication process, friction is reduced and the resulting chips are removed from the cutting zone, helping to extend the tool life and increase the machining quality [11]. However, the use of cooling fluids has an important place in both production costs and threatens the environment and human health [12,13]. For this reason, it is an important research topic for today's researchers to reduce the amount of cooling fluid used during cutting due to the employee health and environmental influences as well as the desire to reduce production costs.…”

In this study, machinability studies of Titanium (Ti) and its alloys construction, under the minimum quantity lubrication (MQL) system has been investigated. Titanium and its alloys, which are made of lightweight metals, are extremely difficult and costly to process. The main purpose of this article is to contribute to the scientific work in this area and assist in the selection of the correct cutting tool, machining operation and cutting parameters during processing of Ti and its alloys. Another aim of the study is to examine the effects of the use of the MQL system in the automotive, aerospace, and space industries on the machinability of Ti and its alloys, which are strategic priorities. In order to reach all these objectives, studies on Ti and their alloys processed with MQL system in the world have been examined and their results have been given.

“…The poor thermal conductivity of titanium and its variants, the heat generated at the interface between the tool and workpiece and low volumetric heat capacity of titanium and its alloys retard dissipation of heat to the surrounding. So, about 80% of the heat generated at the interface is conducted by the tool, hence causing rapid tool wear [6][7][8][9]. The low elastic modulus of titanium alloys leads to high spring back which causes vibrations during machining and ultimately results in poor surface finish [8,10].…”

The low elastic modulus of titanium alloys leads to high spring back which causes vibrations during machining and ultimately results in poor surface finish [8,10]. This poor surface finish is not desirable in machined titanium workpiece as they may contain stress raisers like cracks [3,4] which would initiate fatigue failure under inservice conditions.…”

Machining is one of the major contributors to the high cost of titanium-based components. This is as a result of severe tool wear and high volume of waste generated from the workpiece. Research efforts seeking to reduce the cost of titanium alloys have explored the possibility of either eliminating machining as a processing step or optimising parameters for machining titanium alloys. Since the former is still at the infant stage, this article provides a review on the common machining techniques that were used for processing titanium-based components. These techniques are classified into two major categories based on the type of contact between the titanium workpiece and the tool. The two categories were dubbed conventional and non-conventional machining techniques. Most of the parameters that are associated with these techniques and their corresponding machinability indicators were presented. The common machinability indicators that are covered in this review include surface roughness, cutting forces, tool wear rate, chip formation and material removal rate. However, surface roughness, tool wear rate and metal removal rate were emphasised. The critical or optimum combination of parameters for achieving improved machinability was also highlighted. Some recommendations on future research directions are made.

“…Dolayısıyla bu durum, işlenmiş parçaların yüzey pürüzlülüğü ve kalıntı gerilme değerlerini önemli ölçüde etkilemektedir. Kriyojenik soğutmanın kesici takım performansı ve yüzey bütünlüğü üzerindeki olumlu etkileri, sertleştirilmiş çelikler [6], nikel alaşımları [7], titanyum alaşımları [8], paslanmaz çelikler [9] ve metal matrisli kompozitler [10] gibi işlenebilirliği zor malzemelerin talaşlı imalat çalışmalarında belirtilmiştir.

ÖzetSon zamanlarda, çevre ve insan sağlığı üzerideki zararlı etkileri nedeniyle, geleneksel kesme sıvılarının kullanımının, sürdürülebilir imalat yöntemleri ile azaltılması veya ortadan kaldırılması amaçlanmaktadır. Bu sebeple, çevre dostu kesme koşullarının talaşlı imalat proseslerine adaptasyonu, günümüzde daha popüler hale gelmektedir. Bunlar arasında, kriyojenik işleme, özellikle kesilmesi zor malzemelerin talaşlı imalatında, işleme performansını artırmak için etkili bir yöntem olarak da nitelendirilmektedir. Bu çalışma, içten kriyojenik soğutmanın, sertleştirilmiş AISI 52100 rulman çeliğinin bir kesme hızı (200 m/dk), ilerleme (0.1 mm/dev) ve kesme derinliğinde (0.1 mm) tornalanmasında, yüzey pürüzlülüğü ve kalıntı gerilmelere etkilerini araştırmaktadır. Bu amaçla, sıvı azot (LN2) ve karbondioksit (CO2) iki farklı kriyojenik soğutma ortamı olarak seçilmiştir. Test sonuçları, yüzey kalitesini iyileştirmenin ve daha fazla basma gerilmeleri elde etmenin CO2 koşulunda mümkün olduğunu göstermektedir. AbstractRecently, due to detrimental effects on environment and human health, it is aimed that the usage of conventional cutting fluids is reduced or eliminated by sustainable machining techniques. Therefore, adaptation of environment-friendly cutting conditions to machining processes becomes increasingly more popular today. Among them, cryogenic machining is also characterized as an efficient method to enhance the machining performance especially when machining difficult-to-cut materials. This study investigates the effects of internal cryogenic cooling on surface roughness and residual stresses in turning of hardened AISI 52100 bearing steel at a cutting speed (200 m/min), feed (0.1 mm/rev) and depth of cut (0.1 mm). For that purpose, liquid nitrogen (LN2) and carbon dioxide (CO2) are selected as two different cryogenic cooling media. The test results show that it is possible to enhance surface quality and to obtain more compressive residual stresses under CO2 condition.
