“…Especially in some special and extreme cases, such as the vibration monitoring of equipment transmission parts in some sealing environment and mechanical rotation environment, it is difficult to realize the external power supply [46][47][48][49]. Piezoelectric vibration sensing technology has the advantages of high sensitivity, wide frequency range and self-powered supply, but it is greatly affected by the ambient temperature and humidity of the ship [50][51][52][53][54][55][56].…”

With the rapid development of advanced electronics/materials and manufacturing, marine vibration sensors have made great progress in the field of ship and ocean engineering, which could cater to the development trend of marine Internet of Things (IoT) and smart shipping. However, the use of conventional power supply models requires periodic recharging or replacement of batteries due to limited battery life, which greatly causes too much inconvenience and maintenance consumption, and may also pose a potential risk to the marine environment. By using the coupling effect of contact electrification and electrostatic induction, triboelectric nanogenerators (TENGs) were demonstrated to efficiently convert mechanical vibration movements into electrical signals for sensing the vibration amplitude, direction, frequency, velocity, and acceleration. In this article, according to the two working modes of harmonic vibration and non-harmonic vibration, the latest representative achievements of TENG-based vibration sensors for sensing mechanical vibration signals are comprehensively reviewed. This review not only covers the fundamental working mechanism, rational structural design, and analysis of practical application scenarios, but also investigates the characteristics of harmonic vibration and non-harmonic vibration. Finally, perspectives and challenges regarding TENG-based marine self-powered vibration sensors at present are discussed.

“…Aspects of quality assurance, highlighted in technical literature, are very diverse. Significant attention is given to the problem of ensuring the surface roughness of workpieces during turning [1][2][3], milling [7,8], grinding [9], as well as modeling, prediction and optimization of surface roughness expected after processing [9][10][11][12][13][14].…”

The paper considers the problem of accuracy assurance during part manufacturing. Ensuring the required accuracy is one of the aspects of achieving the level of quality, implied during product design. It should start even before the actual manufacturing process, during process planning, which is one of the main stages in product life-cycle. In digital manufacturing, while using automatic and semi-automatic equipment, including CNC machines, a multi-operational technological process must be reliable in the context of ensuring its accuracy parameters, i.e. must guarantee in advance the compliance with requirements of dimensional accuracy and surfaces location and orientation which is specified in a part drawing. This can be achieved by carrying out a dimensional accuracy analysis of a technological process at its design stage, which will reduce time and material costs when introduced in production, due to a significant decrease in the probability of obtaining defects, related to precision parameters. When conducting a dimensional accuracy analysis of a technological process, it is necessary to preliminarily create diagrams of linear dimensions and circular runouts. Creating these diagrams and performing the required calculations manually is a rather time-consuming process. This fact as well as the lack of necessary software packages (even though there exist several programs for calculating linear and diametric dimensions and machining allowances, developed by authors of the present paper) today at industrial enterprises engineers do not conduct dimensional accuracy analysis when designing multi-operational manufacturing processes and rely solely on their own experience and the experience of adjusters and CNC machine operators. And this, in turn, holds back the process of manufacturing process automation, which is unacceptable during the transition to digital manufacturing. As a solution to this problem, it is proposed to introduce into the practice of technological process design developed calculation programs and a software tool in development, based on methods of interactive synthesis of linear dimensional and runout diagrams, described in the paper.
