“…This might be due to the thermal softening and of the work material which needs less energy to deform hence fewer cutting forces. [33][34][35] At the exit of the first tooth, little adversity in F x (Figure 8(a1)) is observed which may be due to the cutter runout and rapid disengagement of the ball end milling cutter tooth. At the entry and exit of the cutter, it has been observed that the axial force values are higher than the tangential forces which suggests the presence of indentation at the entry and exit of the cutter.…”

Due to the intricate geometry, force prediction in the ball end milling process (BMP) is a challenging task. Cutting forces generated during BMP have an impact on important aspects of machining characteristics such as form error, chatter and vibration, surface finish, tool wear, and dimensional accuracy. These machining problems might be resolved by foreknowledge of the cutting forces. In the present research, a new and quick mathematical model based on the linear mechanistic method is reported to determine the force coefficients. The cutter’s hemispherical part is discretized into five discs along the axis at 0.4 mm uniform spacing in the range of 0.2–1.8 mm. For one cutter revolution, forces in the tangential, radial, and axial directions are measured for each disc to prevent radial runout. The current disc makes use of the preceding disc’s cutting force. To derive the shear and edge force coefficients, these are further divided into edge and shear forces. Validation experiments have been conducted and compared with the simulated forces to assess the predictive power of the developed force coefficient model. The predicted results are found to be remarkably close to the experimental results with an error of 5.5%, −8.6%, and 8.9% at 6631 rpm and 2.8%, −4.4%, and 2.21% at 10,052 rpm in tangential, radial, and axial forces, respectively.

“…Typically, cutting tool manufacturers supply tools to crucial industries such as automotive, aerospace, transportation, general engineering, and defense sectors that have stringent quality and compliance requirements. These tools are dual-use products that can be used in civil applications such as machining agricultural pump components [48] but are also capable of manufacturing aerospace, ballistic, or fighter jet parts [49]. In addition, most countries rely on importing essential industrial raw materials such as tungsten carbide and cobalt [50] to manufacture the tools.…”

Background: Blockchain is a digitally managed, distributed, and decentralized ledger used to record transactions in an immutable format. Its characteristics in providing trust, transparency, and traceability make it attractive for applications where transactions are involved. Originally intended to support financial transactions, the technology has gained attention even in non-financial sectors such as health care, manufacturing, retail, and government services. Methods: For centuries, the various functions of manufacturing industries have worked based on the relationship and trust that they have with their upstream and downstream stakeholders. In addition, as the conventional factories are growing into giant gigafactories, the participation of several intermediaries further complicates the supply chain and logistics operations. Hence, the article aims to provide a comprehensive overview of the role of blockchain technology in addressing supply chain and logistics-related challenges by analyzing, organizing, and reviewing the literature. Results: The study shows that blockchain technology can transform the supply chain and logistics into secure, agile, trusted, and transparent functions. A conceptualized application scenario demonstrates the benefits of blockchain technology in providing provenance and traceability to critical products. Conclusions: In particular, a private or permissioned blockchain is suitable for multi-organizational businesses such as supply chain and logistics. In addition, IoT-blockchain integration, smart contracts, and asset tracking has immense benefits in the future.

The machining of Aluminum-based Metal Matrix Composites (Al-MMCs) is challenging due to their inhomogeneity, anisotropic nature, and dynamic cutting forces. In this paper, the effect of machining parameters, including cutting speed, feed rate, and depth of cut, on surface quality (Ra) and main (Normal) cutting forces (Fc) during turning of Al-MMCs under different cutting conditions (DRY, WET, and MQL) was investigated. Statistical analysis tools were used to analyze the experimental results, and ANOVA and RSM techniques were used to model the relationships between machining parameters and responses. The results showed that feed rate significantly affected both Ra and Fc for all machining conditions. The DRY machining mode was optimal for surface finish, and the MQL mode was effective in reducing cutting forces due to its cooling and lubrication properties. A feed rate of 0.03 mm rev−1 was found to be the most favourable for all cutting environments as it resulted in lower Ra and Fc values. Turning in the WET condition also produced lower Ra due to the effective flushing of chips and cleaning of the cutting zone. In contrast, turning in the MQL condition reduced cutting forces by 17% and 50% as compared with dry and Wet conditions respectively under optimal conditions. Similarly, surface roughness improves under dry conditions by 33% and 3% compared to Wet and MQL conditions.
