“…Samples GJGJG and GBGBG have a higher FS than samples GJBJG and GBJBG, which is attributed to the presence of a considerable fraction of glass fibers [25]. FS and stiffness are provided by these fibers in the skin layers [26]. Bamboo fiber plies have lower flexural strength than jute fiber plies models because of their extensible nature.…”

This article investigates and presents the upshots observed in the brook of hybrid composites especially, the current investigation focuses on the impact of fiber composition, sequence, and stacking pattern on composite mechanical Features. Five varied stacking sequences of hybrid composites encompassing laminates are used to create four classes of fiber with jute/bamboo/glass by utilizing a conscientious hand lay-up process with glass fiber-laced mats as their peripheral layer. For examination, fiber sequences are arranged in the combination of GJBJG, GBJBG, GJGJG, and GBGBG, where G, J, and B refer to glass fiber, jute fiber, and bamboo fiber, respectively. The position of fiber in the core layer is kept in a perpendicular direction with respect to adjacent piles which might be jute or bamboo fiber and the best position of fiber is considered due to the stacking order. Stress and strain were linear in the load versus deflection curves, and all of the samples failed quickly, it is observed that the sample containing a higher or considerable number of bamboo fiber layers exhibited increased strain and toughness. In comparison to other samples, embolism of glass fiber as the main and covering layer expressed a higher impact on the mechanical properties of the composites is observed in this investigation. The shattered sample morphology demonstrated that the matrix and reinforcements were compatible.

“…Acoustic emission has attained notable focus in the engineering community in recent years, both in contact sensors [22][23][24][25] and non-contact ones [26][27][28] in a wide range of applications. Besides the use of AE sensors in the machining field, it has also been used in detecting weak points in metallic structures such as piping [29], aircraft [30], windmills [31] and even bone-milling surgery [32].…”

This work presents a non-invasive and low-cost alternative to traditional methods for measuring the performance of machining processes directly on existing machine tools. A prototype measuring system has been developed based on non-contact microphones, a custom designed signal conditioning board and signal processing techniques that take advantage of the underlying physics of the machining process. Experiments have been conducted to estimate the depth of cut during end-milling process by means of the measurement of the acoustic emission energy generated during operation. Moreover, the predicted values have been compared with well established methods based on cutting forces measured by dynamometers.

“…Fluctuations in machine tools affect the accuracy and quality of machined surfaces, the durability of tools and machine elements. One of the methods for studying vibrations is the analysis of it acoustic emission [Downey 2016], [Bejaxhin 2019]. Acoustic emission in the machining process comprises information about a cutting process, motor operation, spindle rotating, etc.…”

Improving the accuracy, reliability and performance of high-speed technological systems is one of the most pressing challenges in modern industry. The process of improvements in machine tools is permanent because of growth in requirements for the parts quality. The HSM process progress may depends on specific characteristics of particular machine. In this connection, there is a need to carry out investigations in real equipment. The possibility of in-process parameters registration using CNC capabilities is considered. Hardware and software solutions are proposed. The software capabilities for data processing, analyzing and displaying a large number of graphs are shown.
