“…The measurements were carried out using of a stylus profilometer (Hommel Tester T8000; Hommelwerke GmbH, Villingen-Schwenningen, Germany), which was more widely presented in the works of Kałonek et al [29,30]. The instrument was equipped with a TKU-100 pick-up with a diamond stylus tip (opening angle: 90 • , tip radius: 1.5 µm).…”

The condition of the cutting tool is one of the most important factors as it directly affects the technological and economic efficiencies of the woodworking process. The large variety of raw materials of wood combined with possible impurities and inclusion of solids puts high demands on planing machines. One of the methods to modify their operational properties is to apply antiwear coating on their working surfaces using vacuum deposition methods, such as physical vapor deposition (PVD). The use of such coatings reduces the adhesion of planing products to the surface of industrial planer knives, reduces the friction between the cutting tool and the workpiece, and limits the penetration of heat into the tool, thereby contributing to extending its effective working life. This study examines the impact of PVD-based CrCN/CrN coating on the operational durability and intensity of wear of planer knives operating in production conditions compared to unmodified knives (typically used in the wood processing industry for pine wood planing). For the unmodified and CrCN/CrN-coated planing blades (before and after processing), detailed analyses were carried out. These analyses included determining the rounding radius and profile along the blade (worn edge displacement), calculating surface texture parameters of the rake face of planer knives, and carrying out visual microscopic analysis of its condition. The results of the experiments indicated an increase in durability of up to 142% for the CrCN/CrN-coated tools. It was also found that the use of PVD-based modified industrial planer knives turned out to be more beneficial in each analyzed area of analysis.

“…During the studies, an increase in the grinding power ΔP, material removal V w and grinding wheel volume wear V s were observed, while following its termination, the value of the G grinding index was determined, along with values of selected machined surface roughness parameters on the basis of the measurements carried out using a Hommel-Tester T8000 stylus profilometer (Hommelwerke GmbH, Villingen-Schwenningen, Germany) [42] and TalyMap Silver 4.1.2 (Digital Surf, Besançon, France) software. Assessment of the grinding wheel active surface (GWAS) condition after grinding was carried out by the use of SEM micrographs acquired by a JSM-5500LV scanning electron microscope (JEOL Ltd., Tokyo, Japan) [43], as well as mapping elemental composition and analysis of EDS spectra registered by the system based on an Explorer™ scanning electron microscope (ASPEX Corp., Delmont, PA, USA) [44,45] equipped with an SDD EDS OmegaMax™ detector by the same producer.…”

In the paper, the results of experimental studies related with determination of the influence of the supply of a grinding fluid (GF) doped with powdered graphite and MoS 2 into the machining zone with the minimum quantity cooling (MQC) method on the course and results of the reciprocating internal cylindrical grinding of rings made from Inconel® alloy 718 have been presented. As a grinding fluid, water aerosols were used. The aerosols delivered the following into the grinding zone: water slurry MoS 2 with a concentration of 30 g/dm 3 , water slurry of graphite with a concentration of 30 g/dm 3 , 5% water solution of Syntilo RHS oil and pure demineralized water. The obtained results of carried out experiments showed that the most favorable conditions of grinding wheel operation were obtained when MQC-based delivering an aerosol of water slurry made from demineralized water doped with MoS 2 and graphite with a minimum flow rate and when delivering an aerosol of 5% water slurry of Syntilo RHS oil. It was proved that doping GF with powdered MoS 2 and graphite, with delivery in the form of an aerosol with a minimum flow rate, has a substantial influence on the intensity of clogging grinding wheel active surface (GWAS). Additionally, it has been demonstrated that the solid grease MoS 2 and graphite particles reached the area of contact of the GWAS and the machined surface effectively, actively influencing its tribological conditions of the grinding process.

“…Stylus profilometer, one of the major breakthroughs in mechanical measurement methods Kapłonek et al (2017) involves the use of a conical blade with a rounded tip (2, 2.5, 5 and 10 mm) by Lee and Cho (2012) and Smith (2002) that traces the surface in which roughness is to be measure. The signal received after amplification is sent to the processing system of the computer and values of selected parameters and surface roughness functions are obtained.…”

Purpose Additive manufacturing has paved a way for geometrical freedom and mass customization of new and innovative products. However, it has a few limitations in printing complex geometries and sizes. The purpose of this paper is three-dimensional printing of metal parts using selective laser melting (SLM) has several intricacies. Design/methodology/approach To test the capabilities of SLM, the complex geometries of varying sizes, orientations, shapes such as square and cylindrical features, thin wall structures and holes were checked for dimensional accuracy and surface roughness. Findings The outcome of the study represents the capabilities of SLM and provide insight for solving the technological issues and processing constraint in the manufacture of metal parts from aluminum alloy. The analysis has proven that there is significant accuracy in dimension for large features in comparison with smaller one. The dimensional reproducibility was determined with the aid of an optical measuring system and the range of errors were calculated. These results show that the dimensional accuracy of the features in the printed part was within acceptable tolerance limits. This paper also investigated the significant contributing factors influencing printing of two and three-dimensional surface roughness based on the result of surface profilometer and it was observed that the surface was smoothened with the presence of overhangs and supports. Originality/value The ability of SLM to fabricate conformer cooling channels to support mould fabrication was tested. From the experimental result, it was observed that the quality of printing of conformal cooling channels depended on the diameter of channels with larger distortions in the channel having smaller diameter. The innovative aspect of the work was the study of build orientation combined with the investigated material.
