Study On Impact Of Dust Particles Towards Planetary Ball Milling Machine's Maintenance, Reliability And Performance Using DOE.

Di industri pengeluaran, keupayaan untuk memenuhi kehendak pelanggan dari segi masa penghantaran dan qualiti produk merupakan objektif utama bagi setiap pengeluar. Salah satu kriteria untuk mencapai objektif ini ialah dengan memastikan mesin-mesin untuk proses pengeluaran beroperasi dengan lancar tanpa atau kurang berlakunya kerosakan secara tiba-tiba . Preventive Maintenance (PM) is one of the strategies that can be applied to reduce the machine breakdown problem due to unplanned maintenance. However, the application of PM in term of when is the best time to carry out the PM is an important issue. The answer to this question should be based on an adequate maintenance analysis

Identifying the Best Fit Failure Distribution and the Parameters of Machine’s Component: A New Approach.

In industries, failure of the equipment to function became a major contribution to the production losses and high maintenance cost

The Application Of Preventive Replacement Strategy On Machine Component In Deteriorating Condition – A Case Study In The Processing Industries.

The operation of a particular component in deteriorating condition will lead to a high machine downtime. This is due to the failure of component at unexpected time. As a result it will increase cost of maintenance and production lost. One of the solutions to this matter is to use Preventive Replacement (PR)

Mechanical Assemblies Design Of Underwater Electric Motor.

Electric motor plays an important role in providing Autonomous Underwater Vehicle (AUV) system the capability for motion

COMPARISON OF FRICTION STIR AND TUNGSTEN INERT GAS WELDMENTS OF AA6061-T6

In this research, 6061-T6 aluminum alloys were welded using friction stir welding and tungsten inert as techniques in order to investigate the microstructure and mechanical properties. FSW of aluminium alloys has showed better mechanical properties compared to the conventional welding, tungsten inert gas (TIG). FSW weldment did not show any pores at the nugget zone compared to fusion zone in TIG weldment which produced a lot of pores

Influence of semi-solid casting and equal channel pressing on microstructure of a hypoeutectic Al-Si alloy

The aim of this work was to develop understanding of microstructural evolution of the alloy casted in semi-solid condition using a cooling slope and conventional casting followed by ECAP in a 120 die. Feed materials were prepared by cooling slope casting and conventional casting for ECAP process. The microstructures and Vickers hardness of the worked materials extruded by two routes (A and B) were evaluated. The primary α-Al phase tends to be elongated after processing by route A. However, its morphology was similar in nature to the microstructure of the as-cast sample after processing by route B. The Si particles become fragmented during ECAP processing and are more nearly globular in shape and uniform in size than in the as-cast sample. The microstructure of the semi-solid cast ECAPed samples was more homogenous than that of the conventional cast ECAPed sample followed by ECAP for both routes. The hardness of semi-solid cast ECAP samples was also higher than that of conventional cast ECAPed samples for both routes
