Modern-day technologies are described by very high-level of computerization, deploying composite and sophisticated machines. The objective behind is to achieve higher productivity and profit in an organization. Therefore it is always desirable to achieve maximum calculated output from every machine in the industry. Reduction in downtime is a step towards getting a maximum output from machines by improving their reliability and availability. In the present research work a systematic approach for Maintenance Planning and Control (as Modified Six Step Method) has been applied on one of the...

In the present research work experimental investigations has been made for development of Al- Al2O3 MMC (metal matrix composite) by combining stir casting and ABS (acrylonitrile butadiene styrene) replica based investment casting. The research started with selection of the standard geometrical component (cube for the present study).The research highlights the effect of reinforcement Al2O3 on mechanical and metallurgical properties of Al based MMC. The input parameters of process are material composition, layer combination and pouring temperature in investment casting. The study highlights...

The purpose of the present study is to compare investment castings prepared with conventional wax based patterns and Acrylonitrile Butadiene Styrene (ABS) based patterns for bio-medical implant (hip joint). Starting from the identification of component, patterns with three different types of pattern materials (namely: wax, ABS and ABS+wax) were prepared under different experimental conditions. Dimensional measurements were made on the final castings prepared. The results of study highlights that casting with ABS based pattern gives better dimensional accuracy (under given experimental...
