Abstract:
Based on the thermal
susceptible theory of precision machine, a heat excitation device with
microcomputer is projected and manufactured, further, a new method is
presented in order to study thermal characteristic of precision machine.
The new method of artificial heat excitation can be employed
effectively, quickly and non-destructively in researching the function
of different internal heat sources, and identifying the thermal weak
link which affects working accuracy in machine system. Therefore, the
heat excitation technique can provide the scientific foundation
improving weak links or realizing temperature control.
