Investigation of the Effect of Built Orientation on Mechanical Properties and Total Cost of FDM Parts

Lubricants based on hydrocarbon-type mixtures do not satisfy all requirements of OEMs (Original equipment manufacturers) for modern applications. The usual solution is the addition of small amounts of certain additive compounds that render significant improvements in base oil properties such as oxidative degradation, tribological performance and other characteristics. This study examined the tribological behavior of copper oxide nanoparticles as additives in mineral based multi-grade engine oil. All tests were performed under varying loads and concentrations of nanoparticles in lubricating oil. The friction and wear experiments were performed using pin on disc tribotester. The results demonstrated that nanoparticle additives can effectively improve the engine oil lubricating properties. This is because nanoparticles enter the friction zone along with the flow of lubricant. They convert sliding friction into rolling friction, thus reducing the effective friction coefficient. This work also included an analysis of worn surface morphology by scanning electron microscopy. This surface examination revealed that nanoparticle additives resulted in smoother worn surfaces. From the viscosity test it can be inferred that viscosity of engine oil contains CuO nanoparticles is a function of nanoparticles concentration. Stribeck curves are used to reveal the lubrication regimes where the CuO nano-particles are most effective. It was found that the addition of CuO nanoparticles to the base oil results in up to 50% reduction in coefficient of friction in the mixed lubricant regime.

Purpose – Manufacturing organizations are under pressure to improve productivity and reduce costs through the realization of lean manufacturing. This paper approaches lean manufacturing and aims to identify and measure the intimately associated parameters of lean manufacturing and also examines the weight of their contribution to overall lean manufacturing.Design/methodology/approach – A questionnaire survey study was performed in Indian manufacturing industries to collect data. The reliability of the survey instrument was pre‐tested and an acceptable value of Cronbach's α (a reliability coefficient) was found. Three experts determined the relative weight of various parameters using analytical hierarchy process (AHP). Pearson's coefficient of correlation analysis was used to measure the strength of the relationships between various parameters of lean manufacturing.Findings – The experts found “elimination of waste” to be the most important parameter of lean manufacturing, followed by “just in time deliver...

Metal matrix composites have evoked a keen interest from the automobile and aerospace sectors owing to their attractive mechanical properties and applications. Over the past two decades, researchers have unearthed many secrets pertaining to these advanced materials. This paper briefly reviews the research revelations of the mechanisms that make these materials so superior. Turning of metal matrix composites is focused in particular. Mechanisms such as particle fracture, particle pullout, debonding, dislocation phenomena, thermal softening, wear modes, surface generation, cutting forces, chip formation, strains and stresses are addressed. Discussions on related phenomena such as effects of tool coatings, adhesion, friction, microstructures and strain hardening are also presented.
