Effect of Machine Parameters on Drilling Process of PCB

A study of effect of drilling parameters like feed rates, cutting speeds and geometry of drill tool, surface roughness, cutting forces and chip formation is done in project. Machining a material removal process, is one of the most widely used manufacturing processes. At high spindle speed and lower feed rate the heat generation due to friction between cutting edges and the work material facilitate softening of the matrix which resulted in poor surface finish and lower delamination. Drilling is a type of machining operation where a cutting tool is used to create holes inside the work piece. A proper selection of tool and drilling parameters can reduce the risk of hole damages.
