    Abstract: The effect of thermal vibrations on modal frequencies of flexural vibration for a scanning thermal
    microscope _SThM_ cantilever probe has been evaluated using the Timoshenko beam model,
    including the effects of rotary inertia and shear deformation, and an analytical expression for the
    frequencies of vibration modes has been obtained. According to this analysis, the thermal vibration
    effect makes the probe stiffer and leads to an increasing frequency in the nanomachining process.
    This phenomenon may result in a rough machined surface of the materials. The resonant frequency
    of vibration modes decreases as the length-to-thickness ratio of the probe increases. The mode shape
    decreases with increasing the operating temperature in SThM machining. In addition, the results
    based on Euler beam and Timoshenko beam models are compared. It can be found that the
    Timoshenko beam model is able to predict the frequencies of flexural vibration of the higher modes
    for the SThM cantilever probe nanomachining
