Increase Drilling Efficiency with Accurate Mathematical and Physical Calculations

Abstract
The purpose of this paper is to calculate the forces that are effective in drilling from the point of view of mathematics and physics. With precise mathematical calculations, the drilling process can be optimized. Drilling operation. Optimization of drilling could save time and cost of operation and increases the profit. In present experimental investigation analyses the physical effect of various machining parameters i.e. cutting speed, the feed rate and the drill diameter on the quality of the drilled holes. Hole delamination of each hole is measured with help of radiography. Taguhi's and Anova Technique have been employed to study the effect of the interactions between different drilling parameters on delamination of holes. After experiments suggests the optimal conditions for minimum hole delamination and surface roughness. Key words - Best angle, Composition operator, admissible weight
