Abstract

In this project an overall design the hoists generally confirm to IS: 3177 of the hoisting mechanism of an EOT crane has been carried out. The dimensions of the main components have been determined for a load capacity of 50 ton crane having 8 rope falls. Various dimensions for cross sections of various shapes for crane have been found. After the system was designed, the stress and deflection are calculated at critical points using ANSYS and optimized. Which cross section would be better keeping some parameters constant for all the case .Various dimensions and load per wire for wire ropes has been found.

 Using various formulae found the dimensions for pulley, Rope-drum.

Also calculated the Power and ratings for the motor brakes used in the hoist mechanism.

Abstract

Objective of this paper is development of first principle based model of grate cooler for cement plant. In this work, the temperature variation and assumptions of the model will be discussed. The model is developed for steady state condition. Variations of gas, solid temperature, wall temperature and heat losses through the wall are simulated with respect to grate cooler length. The model is validated by comparing the output with the published experimental simulation data and by observing the response to step changes. Step changes are used for validation and to understand the influence of various design and operating parameters on grate cooler performance.

Abstract

Due to emerging concepts like globalization and liberalization today customer have choice to change their demands frequently? Hence market life of product reduces. Conventional senescent manufacturing machine tools cannot meet these requirements. In order to sustain competition and exist in global market, Indian manufacturing industries need to upgrade its technology for its very survival and also to sharpen its long term competitive edge. This is possible by upgrading the senescent machine tools to restore accuracy level, improving availability, enhancing productivity & capability. CNC Retrofitting is a cost effective method of upgrading capabilities of existing machine tools. Suggestions regarding future work are incorporated herewith. Feasibility of retrofitting is analyzed by means of case study.

Abstract

In this research work the effect and optimization of machining parameters on surface roughness and material removal rate (MRR) in a turning operation are investigated by using the Taguchi method. The experimental studies are conducted under varying cutting parameters including cutting speed, feed rate, depth of cut and cutting nose radius of insert. An L9 orthogonal array, the signal-to-noise (S/N) ratio are employed to the study the performance characteristics in the turning of AISI 1045 Mild steel using WNMG331RP, WNMG332RP and WNMG333RP carbide inserts on CNC turning center. The conclusions revealed that the feed rate and nose radius were the most influential factors on the surface roughness and Material Removal Rate (MRR) in CNC turning process is greatly influenced by depth of cut followed by cutting speed. For simultaneous optimization of Surface roughness (Ra) and material removal rate (MRR) depth of cut is the most significant parameter affecting the performance followed by the nose radius.

Abstract

Surface Roughness and tolerance are among the most critical measures in many mechanical products as competition grows closer customers now have increasingly demanding for high quality; making surface roughness one of the most competitive dimension in today’s manufacturing industries surface of mechanical product can be created with a number of manufacturing process. This works applies the frictional factorial experimentation approach to study the impact of turning parameters on the roughness turned surfaces analysis of variance is used to examine the impact of turning factors and factor interaction on surface roughness.
