In copper wire, real time crimp monitoring has traditionally been based on force measurement during the crimp cycle. The force attributed to molding the copper wire into the terminal is a significant portion of the total force needed to form the crimp. Therefore, any wire deviations from the norm is translated into a force pattern aberration that can be detected using basic signal pattern analysis. As the industry is contemplating replacing copper wire with aluminum wire, in order to save on weight and material cost, the traditional force monitoring becomes ineffective in detecting wire faults in the crimp. The reason is that aluminum is a softer material than copper, and most of the force exerted during the crimp cycle is consumed by forming the copper terminal itself. The small force deviation due to aluminum wire fault becomes much more difficult to detect. Therefore, a new technique is needed to monitor crimped aluminum wires.

Fatigue behavior of flow drill screw (FDS) joints in lap-shear specimens of aluminum 6082-T6 sheets with and without clearance hole are investigated based on experiments and a structural stress fatigue life estimation model. Lap-shear specimens with FDS joints were tested under quasi-static and cyclic loading conditions. Optical micrographs show that the failure modes of the FDS joints in specimens with and without clearance hole are quite similar under quasi-static and cyclic loading conditions. The fatigue lives of the FDS joints in specimens with clearance hole are longer than those of the FDS joints in specimens without clearance hole for given load ranges under cyclic loading conditions. A structural stress fatigue life estimation model is adopted to estimate the fatigue lives of the FDS joints in lap-shear specimens. The closed from structural stress solution is based on the analytical solution for a plate with a rigid inclusion under a resultant shear load.

In the present study, the enhancement of an engine performance and emission characteristics by the addition of nanoparticles to the fuel is presented. In this regard, Aluminum Oxide (Al2O3) Nanoparticles were utilized as fuel additive in a single cylinder, direct injection four stroke diesel engine. Two percentages of 0.1and 0.5% by weight of Al2O3 were tested and compared to regular diesel fuel. The results showed that nano-sized aluminum oxide can improve the performance of diesel engines and reduce the emission of pollutants like CO2 and HC compared to conventional diesel fuel. Furthermore, the results indicated that the nano-fuel with nanoparticle concentration of 0.5 % gives better performance characteristics in comparison with that of 0.1 %. However, the only downside of the nanoparticle addition was the increase in the CO emissions.

Stamping die design recommendations attempt to limit the production of burrs through accurate alignment of the upper and lower trimming edges. For aluminum automotive exterior panels, this translates to a gap less than 0.1 mm. However, quality of sheared edge and sheared edge stretchability are affected by stiffness of trimming tool and cutting edge condition. The objective of the study is to investigate the influences of trimming tool stiffness and trimming edge condition on sheared edge stretchability of aluminum blanks 6111-T4. For experimental study, one side of the sample had sheared surface obtained by the trimming process while the other side of the sample had a smooth surface by metal finish. Burr heights of the sheared edge after different trimming configurations with 10% clearance were measured. Subsequently, sheared edge stretchability of the specimens was evaluated by measuring major strains of 2 mm circle grids electro-etched on the surface of the samples.

Abstract The paper talks about machining techniques and solution approaches while machining Aluminium grade gearbox housings. Mahindra’s next generation gearbox housings are made totally of Aluminium; along with the higher strength to weight ratio that comes with using Aluminium come highly optimized ribbed structures that aid in achieving the said strength. While machining such Aluminium structures, it is imperative that the clamping forces do not load the component in ways it is not intended to. The paper talks about finish machining and proving out a semi-finished gearbox housing set (front, intermediate plate and rear) on a conventional Horizontal Machining Center (HMC). The input to the machine is the semi-finish housing that is already machined before with stock for finish operations.

Fusing aluminum in a multi-material lightweight vehicle is presented via studies on joining dissimilar materials, joining methods, and the performance of the joined materials. The use of aluminum offers a material that embodies properties to meet new standards as the automotive industry continues to pursue improvements in fuel efficiency and emissions. Aluminum’s strength, light weight, and corrosion resistance offers manufacturers a material alternative to steel and an additional material, which has long been known in the industry, to be employed in automotive construction. Topics of technical interest include: • Forming • Galvanic Corrosion • Welding, Fastening, Bonding • Maximizing Weight Benefits Production of strong, lightweight structures will contribute significantly to automobile manufacturers meeting mandated fuel economy standards, as well as customer preferences for utility, comfort, and safety.
