“…AW2011 uses copper as the alloying element and offers high mechanical strength. The engineering values of material properties of AW2011 are detailed in Table 2 ; they were obtained from the web [ 12 , 13 ]. The table also contains the yield stress and true value of tangent modulus of the AW2011 material to describe the plastic behavior of the cam for computer modeling of the load-bearing capacity.…”

The spring-loaded camming device (SLCD), also known as “friend”, is a simple mechanism used to ensure the safety of the climber through fall prevention. SLCD consists of two pairs of opposing cams rotating separately, with one (single-axle SLCD) or two (dual-axle SLCD) pins connecting the opposing cams, a stem, connected to the pins, providing the attachment of the climbing rope, springs, which simultaneously push cams to a fully expanded position, and an operating element controlling the cam position. The expansion of cams is thus adaptable to allow insertion or removal of the device into/from a rock crack. While the pins, stem, operating element, and springs can be considered optimal, the (especially internal) shape of the cam allows space for improvement, especially where the weight is concerned. This paper focuses on optimizing the internal shape of the dual-axle SLCD cam from the perspective of the weight/stiffness trade-off. For this purpose, two computational models are designed and multi-step topology optimization (TOP) are performed. From the computational models’ point of view, SLCD is considered symmetric and only one cam is optimized and smoothened using parametric curves. Finally, the load-bearing capacity of the new cam design is analyzed. This work is based on practical industry requirements, and the obtained results will be reflected in a new commercial design of SLCD.

Metal cutting fluids (MCFs) play a significant role in cooling and lubricating the cutting zones during various machining operations. The commercially available MCFs like mineral and petroleum oils cater to approximately 75% of the market needs. However, these MCFs harm the worker's health and environment. Therefore, sustainable and eco-friendly MCFs are gaining widespread acceptance in industries. This study critically analyses the recent improvements in metal cutting fluids in drilling, milling, and turning operations with the prospect of accomplishing green and sustainable manufacturing. Furthermore, this study highlights the role of bio-based cutting fluids in the manufacturing industry and the effect of non-bio-based coolants on the environment, and human health hazards are highlighted. In addition, this study analyses minimum quantity lubrication (MQL) techniques applied in various metal-removing operations. Finally, this review article recommends that bio-based cutting fluids combined with MQL techniques can achieve the sustainability goals of the manufacturing industry.

The composite sandwich structures provide the benefits of higher Strength to weight ratio, higher stiffness and flexural strength. The different properties of a sandwich structure depend on various design factors such as material of core and facesheet, thickness of facesheet and core, type of core and panel shape etc. In this study, four different factors i.e. Material of Honeycomb core, Core Height, Facesheet Thickness and Panel Width, with each having three different values have been chosen and a L9 Orthogonal has been generated using Taguchi Design in Minitab 18. After that, 9 different samples have been fabricated as per configurations of L9 OA. Then three point bending test has been performed on these samples and the values of Bending Stiffness, Rigidity and Equivalent Stiffness has been calculated .Then Taguchi Analysis has been performed on the output responses and optimum design parameters have been detected. After that PCA assisted Grey Relation Analysis has been performed on output responses and the values of optimum design parameters for sandwich structure has been obtained.
