ANALYSIS AND REDUCTION OF STRESS IN A CIRCULAR SAW BLADE

Circular saw blade is a valuable multipoint cutting tool used in the manufacturing industry. During the machining process the circular saw undergoes various stresses because of the cutting forces generated, which affect the tool life. So, the current project work helps to select an optimized circular saw blade and provides a method to reduce the stresses developed during the machining process with the help of Hypermesh software and its modules. This project involves the selection of an optimized saw out of three different saw blade (differ in design of type of slots cut) and calculating the stresses developed in the saw during cutting of four different specimens (differ in material). After comparing the results of stresses developed while cutting the four different specimens, maximum stress is calculated. Then the maximum stress is been reduced by using three different coated material. The result of stresses developed after coating the circular saw blade is compared. With the help of this result we can determine the coating material which reduces the maximum stress.
