MATERIAL SELECTION AND TESTING OF HACKSAW BLADE BASED ON MECHANICAL PROPERTIES
Testing of different material blades like High Carbon Steel, Low Alloy Steel, Bi-metallic blade, High speed Steel blades for their hardness, Cutting time performance, Wear Resistance, Tensile Strength and performance under buckling. Experiment of Rockwell Hardness tester for getting Hardness Number on C-Scale for all different types of blades, so their relative hardness of teeth of different blade blades can be compared. For Cutting Performance test, Cutting of same diameter (25mm) job of different materials like Aluminium, Brass, Copper by all blades and their cutting time is noted and compared. For Wear Resistance ability, Profiles of blades-before and after cutting are developed with the help of profile projector and compared. For figuring out Tensile Strength , we carried out Tension test on Universal Testing Machine (UTM), by finding out Modulus of Elasticity (E) value and further analytical calculation can be done for finding Maximum Permissible deflection. Here, we have found out the better blade material for different materials under different mechanical consideration.
