ELIMINATION OF DRILL BREAKING ISSUE DURING OIL HOLE DRILL IN VOLVO CRANK SHAFT

During the manufacture of crankshaft for Volvo heavy vehicles, oil holes drill is essential for lubrication purpose. Drill bits are used for the above drilling purpose. The drill bits break due to abnormalities such as coolant pressure, drill cutting edge blunt, rigidity etc. To eliminate this breakage issue, some of the essential parameters such as point angle, honing angle, lip height etc. of drill nomenclature as well another factor like coolant, speed, machine malfunction etc. are modified. This project deals with breakage analysis of existing drill bit due to vertical machine parameters and constituent conditions of the machine during drilling.
