“…The blade workpiece pressure side thickness is measured in 9 sections in areas δ1 and δ2, and the blade workpiece back thickness is measured in 8 sections in areas δ3 and δ4 ( Figure 1) [11][12][13]. The result of the control process is the determination of the value of the first maximum from the oscillograph trace, which corresponds to the distance of the transmitted and reflected ultrasonic wave.…”

This paper shows the results of a study of the uniformity of the allowance along the airfoil in the turbine blades workpieces. It is found that in the existing industry, there is a defect associated with a lack of allowance along the airfoil (from the blade back and pressure side) for the polishing operation in order to give the required cleanliness and roughness of the surface layer. By measuring the wall thickness of the blade airfoils, it is concluded that by mechanically modifying the technological bases on the blade, it is possible to select the optimal position of the workpiece in the template instrument, at which the allowance along the airfoil is relatively uniform, and the dimensions of the blade wall thickness will be within the specified tolerance.

“…Recently, various measurement machines and methods have been developed for estimation of tribological properties [13][14][15][16]. Another important issue is estimation of the geometry and its deviation for the parts of complex shape, because the contact area and, therefore, friction in the tribopairs depend on these parameters [17]. In addition, the tribological properties depend on the surface roughness of interacting parts, which makes it important to choose the suitable finishing procedure for the parts of designed systems [18,19].…”

This paper deals with the processes occurring on the surfaces of materials during the interaction between metal and non-metal parts of various biomechatronic devices, such as prostheses, orthoses and exoskeletons. These mechatronic systems require careful selection of materials for design and manufacturing of their parts taking into consideration not only mechanical properties of the materials, but also their tribological characteristics. Friction pairs duralumin-fluoropolymer and stainless steel 100CrMn6-fluoropolymer were chosen for the research as the samples. Experimental research was carried out with the use of the universal friction machine MTU-1. For this research, the scheme "plate-onplate" was used without lubricants. Friction torque, friction coefficient and the temperature in the contact area versus the runtime were obtained as a result of the experiments. Furthermore, estimation of wear of contacting samples was performed. Analysis of the results allowed us to choose suitable materials for design and manufacturing of orthoses, prostheses and exoskeletons.
