Special Issue Information

Dear Colleagues,

We are pleased to invite you to publish original contributions in the area of metallic materials machining. Machining directly plays a pivotal role in manufacturing, which significantly affects socioeconomic development by increasing the environmental, material, energy and labour efficiency of products. A specific characteristic of machining, in comparison with other technologies, is the achievement of the most accurate dimensions and the ability to process all hitherto known materials.

Progress in the technology of machining is achieved by worldwide theoretical and practical works in the many-dimensional professional subject under the pressure of a wide range of needs and requirements of the market. The subject covers synergically interconnected areas of machining theory and technology, machine tools, cutting tools, machined materials, metrology, surface engineering, vibro-diagnostics, manufacturing strategy, ecology and life cycle assessment, among others. Research in the machining area is very important for understanding physical principles, building a knowledge base, innovation in industry and business, and improving environmental conditions.

This Special Issue aims to detail theoretical and practical results of metallic materials for cutting tool and machined workpiece.

In this Special Issue, original research articles and reviews are welcome. It is envisaged that the issue will serve as a forum for publishing contributions which advance in-depth understanding of the relationship between the structure, properties and functions of machined and tooled metallic materials. There will be no restriction on the length of the papers such that the full experimental details should be provided.

Specific research areas of interest for this Special Issue may include (but are not limited to) the following:

  1. Advances in machining of metallic materials
    1. Theoretical and practical achievements in machining of materials
    2. Material preparation methods

Abstract
This study performed high-temperature compression tests at the temperature 900 to 1200 °C and strain rate 0.01 to 10 s−1 to characterize the high-temperature deformation behavior of AISI 4340. The constitutive equation of AISI 4340 was expressed using the Arrhenius model and [...] Read more.
This study performed high-temperature compression tests at the temperature 900 to 1200 °C and strain rate 0.01 to 10 s−1 to characterize the high-temperature deformation behavior of AISI 4340. The constitutive equation of AISI 4340 was expressed using the Arrhenius model and the Zener–Hollomon (Z) parameter. Dynamic Recrystallization (DRX) behavior was evaluated by observing the compressed specimen with Electron Backscatter Diffraction (EBSD). The processing map is based on the dissipation efficiency of the dynamic material model (DMM) and the plastic instability criterion of Ziegler. At strain 0.4, the power dissipation efficiency value is 0.5 or more, and the instable zones are immediately identified through the processing map. The strain, strain rate and temperature data obtained from the FEM simulation of the hot forging process are displayed on the proposed 3D processing map to avoid the flow instability zones and ensure high power dissipation efficiency zones, allowing the operator to control the process’s temperature and speed.

The presented article deals with the influence of the heat treatment of C45 steel on the surface quality after turning. Turning is a machining technology used to prepare specific geometrical characteristics of surface and dimensional quality. In the present paper, the same turning conditions were used for the turning treatment of differently heat-treated steels. The soft annealed state, normalized state, hardened state, quenched and tempered at 530 °C state and quenched and tempered at 660 °C state have been analyzed. By using this approach, it has been possible to evaluate the effects of hardening and machining on the resulting parameters after turning (roughness, cylindricity and circularity). The highest hardness was observed in the steel after the hardening process (694 ± 9 HV 10). The hardening has negatively influenced the surface quality. The high hardness was related to martensite formation and caused a damage to the cutting edge of the cut insert used, leading to a significant change in geometrical accuracy. The cylindricity change achieved 0.15 ± 0.03 mm which was significantly higher compared to the theoretical value of the diameter of the machined steel bar. An inaccuracy was also observed in diameter dimension. These inaccuracies were caused by the wear of the cutting edge of the tool used in cutting parameters setting. Full article
