Thermal Analysis of Whirling Unit attached to Thread Whirling Machine

摘要：

Thread whirling process is a cutting process in which a series of cutting edges on the whirling ring remove material by turning over the rotating workpiece. Whirling unit attached to a thread whirling machine influences much on the machining accuracy because heat generated from motor, cutting tools and bearing is transferred to the spindle. Analyses of temperature distribution, thermal deformation and thermal stress of the whirling unit have been carried out. It is revealed that the highest temperature of 91℃ reaches in the bearing and the thermal deformation of the unit reaches 0.02~0.03mm along X, Y and Z axis. The maximum thermal stress of 31.9MPa is developed in the unit.
