The paper is an evaluation of the surface roughness of various materials produced by water jet cutting (AWJ, abrasive water jet). A 3D laser profilometer developed at the Department of Design and Technical Systems Monitoring at our University was used in roughness measurement. To verify the values measured by the laser profilometer, another measurement was performed using a 2D contact roughness meter. The tests were done on aluminum and stainless-steel materials, respectively. Six samples were produced; three made of stainless steel and three made of aluminum. All samples were produced at a different feed rate of the cutting head. This was adapted to the different roughness required, per the manufacturer’s material data sheets. Varying rates of separation translated into different qualities of the surfaces under evaluation. The evaluated roughness parameters were Ra and Rz. Dependencies were plotted in the chart based on the values measured, which were then compared and evaluated.

“…At this temperature interval heating of the crystalline regions of the microphase of elastic segments occurs. The obtained results are fully consistent with the practical experience of processing and exploitation of initial polyurethanes [1,3,9].…”

“…Wide application of polymeric materials based on polyurethanes is due to the unique combination of high strength properties and elasticity, oil and gas resistance, strike and vibration resistance [1,2]. The relevance of modern technologies [6,7,8,9] is primarily determined by ecological factors -polyurethanes of block structure (block-polyurethanes) provide a unique set of properties and, at the same time, they are also suitable for recycling, are recycled by waste-free technology on high-speed automated equipment, including 3D prototyping methods [17,18]. In addition, block-polyurethanes based on oligoethers have increased hydrolytic resistance, frost resistance, more resistant to microorganisms, and therefore are of particular interest.…”

Polyurethanes are materials usable in wide spectrum of applications. This article is aimed at the properties tailoring of selected polymers by an alteration in initial materials. To achieve that goal, we proposed form the polyurethane matrix by mixing materials that have a different ratio of the initial components. Mathematical model has been developed that describes relationship of structure and strength, deformation, rheological and tribotechnical characteristics of linear block-polyurethanes based on oligoether blends. Oligoethers blend samples were obtained by injection moulding on an automatic thermoplastication machine with varying proportions of the starting components over the whole concentration range. A significant change of properties over the whole concentration range was observed and compositions with unique combination of characteristics have been determined. Obtained dependencies allow to predict the composition of the binary mixture with a tailored level of strength, deformation, rheological and tribotechnical characteristics. The obtained results are fully consistent with the practical experience of processing and exploitation of initial polyurethanes.

“…These instruments have an uncertainty in their measurements. Ambient temperature, the temperature of the system, and the temperature of the part under inspection also influences the precision of the components and of the mounted bearing [ 9 ]. Different methods can be used to measure the size of the parts: touch probes [ 10 , 11 ], air pressure [ 12 , 13 ], and laser systems [ 14 , 15 ].…”

Tapered roller bearings can accommodate high radial loads as well as high axial loads. The manufacturing process consists of machining processes for ring and component assembly. In this contribution, the parameters of influence on the measurement procedure were studied. These parameters of influence were classified as environmental, process, and machine parameters. The main objective of this work was to optimize the process using real-time measurements, which required the study of the influence of several parameters on the measurement uncertainty and how to correct their effects.
