Performance Analysis of Mild Steel (ASTM-60) Under Varying Drilling Conditions Using Taguchi and ANOVA
This study is conducted to analyze the performance of Mild Steel (ASTM-60) using a drill bit (8.25mm &10.25mm high-speed steel) at two different speeds (270 & 630 RPM) under the three conditions (Dry, MQL, and Wet). The Taguchi has been introduced to find out the most influential factors and most of the cases it was drilling conditions. This performance study has been accelerated by using minitab18 software for ANOVA analysis. Thus it gives the clear indication about the effects of RPM, drilling conditions and drill bit size on drilling a particular materials MS (ASTM-60). The conditions and factors have been shown whether it is statistically significant and how much. One conspicuous thing that the interaction between conditions and factors also have the significant effect. The wet cooling condition has shown the better performance on surface roughness for all conditions and drill bit size. The drilling under wet cooling and MQL conditions have almost the same results but it varies in the case of the dry condition. Low RPM is found to be statistically significant than it is for high RPM. The regression line equation can bring the remarkable significance of further drilling Mild Steel at any drilling conditions.
An Approach to Develop Green Environment in Cement Production Plant by Proper Material Handling and Maintenance Management System- A Case Study
Now a days with the huge industrialization material handling and maintenance management systems are going to be most crucial issues of any industry. Its importance cannot be denied in any way as a remarkable percentage of success of an industry depends on these. This article is based on the material handling and maintenance management system of a cement plant where their relevant systems were also studied. It was observed that the profit of any industry along with its working environment of any plant largely depends on the material handling and maintenance management system. In this research some remedial action were proposed regarding to the problems associated with material handling and maintenance management systems. Along with these the safety culture and proper training facilities of the employees were also researched for developing green environment within the cement industry.
