Special Issue Information

Dear Colleagues,

I am pleased to announce the upcoming Special Issue of Materials, focused on the study of the surfaces of metallic materials, especially their experimental and numerical analysis. Metallic materials play a crucial role in many technologies and applications due to their broad range of properties. There are thousands of metallic materials available today and this figure is continuing to grow. Analysis of the surfaces of metallic materials is important for ensuring integrity and quality. In today’s highly competitive market, the need for reliable and high-quality products is greater than ever before. Knowledge of the surface structure of a metal is fundamental in helping to maintain quality control and supporting research and development. Based on the analysis and interpretation of data obtained from the surface of a material, it is possible, for example, to identify topographic functions that must be known for the subsequent prediction and control of a particular technology. Within the interpretation of measured values, it is necessary to systematically analyze the relationships between the parameters and newly formulated physico-mechanical and distribution principles by which they are governed. The generalization of these principles is achieved by means of analytically, correlationally, regressionally and empirically derived equations, with a graphical representation of distribution of their functions. In this Special Issue, the theoretical results, assumptions and requirements of current technological practice will be considered and implemented in relation to the optimization of metallic surfaces. Papers related to measurement methods are also welcome.

Forced rotation turning appears to be an effective machining method due to higher tool life, time efficiency and acceptable quality. Several studies have been carried out to investigate the basic characteristics of forced rotation machining. So far, tools are used whose design included several components. However, such tools may generate vibrations, which are undesirable in the process. In engineering practice, most vibration problems are solved by reducing the cutting parameters (cutting speed and feed rate), which reduces machining productivity. For this reason, a new type of monolithic rotary tool has been designed that eliminates the design complexity and high assembly accuracy requirements of current rotary tools. Based on the performed experimental research, it is possible to define the influence of cutting parameters on the cutting force. Next, the equation of the cutting force and the resulting roughness of the machined surface was determined. In the introduction, the results of the analysis of machining parameters with a rotary tool were added. The presented solution fundamentally validates the new monolithic tool for forced rotation technology and defines its application for different machining materials. Full article

The article aims to use the generated sound as operational information needed for adaptive control of the metalworking process and early monitoring and diagnosis of the condition of the machined materials using a newly introduced surface roughness quality index due to the sound-controlled machining process. The object of the measurement was correlation between the sound intensity generated during cutting and the material parameters of the machined surface, i.e., the roughness of the machined surface and the degree of wear of the cutting tool. The roughness was measured during longitudinal turning of a steel billet with a P25 insert made of 12X18H10T steel and a T15K6 cutting insert made of a titanium, cobalt, and tungsten group alloy. The correlation between the sound and roughness of the machined surface was 0.93, whereas between the sound and wear of the cutting tool was 0.93. The correlation between sound and tool wear in the experiment with P25 and T15K6 cutting inserts and the correlation between sound and roughness is positive. Full article

Despite extensive knowledge of the cutting methods described, no universal method has been developed so far for evaluating the technological quality of elements shaped by different cutting processes. The aim of the research described in this article was to fill this gap and to propose the author’s methodology for the assessment of the technological quality of the surface of X5CRNI18-10 steel shaped as a result of laser cutting and abrasive water jet cutting. A synthetic index of technological quality assessment of the surface after cutting CTQ (cutting technological quality) was proposed. Three groups of factors were taken into account in the assessment of technological quality of the surface after cutting: selected surface texture parameters (arithmetic mean deviation of the surface Sa and total height of the surface St), results of measurements of dimensional accuracy of cut elements (length deviation LD and width deviation WD) as well as indicators of surface morphology estimated on the basis of microscopic images of the surface after cutting (deformation intensity DI and identification of cutting zones ICZ). On the basis of CTQ values determined, the cutting results of both cutting methods were compared. The analyses presented in this paper proved that the CTQ index can be effectively used to compare the results of a cutting process conducted using different methods and under different conditions. The developed CTQ index is a universal valuation tool, allowing for quantitative evaluation of features related to the technological quality of cutting process results. Full article
