Abstract
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 the main sources of heat
generation are assumed as bearings, servo motor and chip formation during machining. Analysis of
temperature distribution, thermal deformation and thermal stress of the whirling unit has been carried
out. It is revealed that the highest temperature of 91°C reaches in the bearing and relative
displacement from point A to tool reaches 0.02~0.03mm along X, Y and Z axis. The maximum
thermal stress of 31.9MPa is developed in the unit.
