Multiaxis cutting force sensors enable smart process control and tool condition monitoring in manufacturing; they allow the detection of workpiece damage and suboptimal surface finish, which can arise from tool wear. Existing methods require complex structure modifications to enhance sensor sensitivity, leading to weakened processing performance and expensive customization costs. This article describes the mechanical design and optimization of a sensory tool holder with embedded piezoelectric sensors in standard tool holders. The design has an almost identical rigidity to that of a regular tool holder. We developed a high-fidelity sensing model by multiaxis piezoelectricity and stress analysis, and optimize the sensor locations and orientations to achieve high sensitivity, accuracy, and cross-axis decoupling in specific directions. Static tests indicated that under optimized parameter configurations, the designed tool holder achieved a maximum cross-coupling error of approximately 4.6%, only half of existing researches; it also demonstrated better performance in sensitivity, linearity, hysteresis, and repeatability. The proposed optimal design was verified by the high fidelity model to have a maximum sensitivity error of only 5.34%, confirming its applicability for sensor embedding optimization in various types of standard tool holders without requiring structure modification.

Engineers and manufacturers can benefit from finite element analysis (FEA) data of mechanical properties of 3D-printed products to enhance the quality and performance. Fused deposition modelling (FDM) is a filament-based rapid prototyping technology that enables the introduction of novel composite materials as long as they can be produced as feedstock filaments. In prior research, a novel material, oil palm fiber composites filament, was produced for FDM. Then, the tensile and flexural test were conducted according to ASTM 638 and ASTM 730 using universal testing machine. In this paper, the uniaxial tensile test, flexural test, and the construction of a material model for the prediction of the stress–strain response were simulated using nonlinear FEA. The plots of Von Mises stress, resulting displacement, and strain were created. In addition, the derived von Mises plasticity material model and boundary conditions accurately represented the behavior of the specimen under uniaxial tension load, with only minimal differences between actual and theoretical results. The tensile and flexural strengths of oil palm fiber composite (3 wt%) were 33.14 and 33.81 MPa, respectively, according to the results of the FEA simulation. The difference between simulation and experimental error was minor, ranging from 5.4 to 15.2 percent. The aim of this research was to apply non-linear FEA to validate experimental results from tensile and flexural tests of oil palm fiber composites filament, which would be used as a raw material for FDM. © 2022

This study reports the effects of post-annealing on the electrical reliability of a NiAl/SiO2 interconnect structure for potential use as post-Cu interconnect. Our materials characterization using transmission electron microscopy and secondary ion mass spectrometry discloses that annealing at elevated temperatures induced the diffusion of Al into SiO2: Al, for a 400 ºC-annealed sample, diffused only to a few nanometers from the interface, forming a thin aluminum-rich oxide layer, while samples annealed at higher temperatures show an extensive Al diffusion and interfacial reactions. In a voltage ramp dielectric breakdown test, the 400 ºC annealed sample shows the lowest breakdown voltage, possibly, due to the aluminum-rich oxide layer serving as a self-forming barrier while the samples annealed at higher temperatures display a drastic reliability degradation with the annealing temperature increasing. In addition, analyzing data acquired from time-dependent dielectric breakdown tests using the E-model helps us predict the lifetime of the 400 ºC sample to be longer than 105 hours at 1 MV/cm. © 2024, The Authors.
