Effect Of Varying Machining Point On Deformation Of Crankshaft Pin In Orbital Grinding System
In this study, the influence of varying machining point on the deformation of a crankshaft pin is investigated. The
model is simplified with the stock and vibration dampeners replaced by stiffnesses. While the grinding wheel machines the pin
part, the force acting on the work piece changes continuously. Analysis was done for 24 positions: 360 degrees was divided
with 15 degree interval. The deformations are toward the center when the pin position is under the wheel center, but slightly
outward the center when the pin position is over the wheel center. This is because the gravitation affects the deformation
significantly. In addition, while the machined pin position and force direction change, the vibration dampener positions were
fixed. This affects the deformation.
