Abstract
An intelligent warm-up method of machine tool, applicable to a machine tool, includes: a step of, based on temperature change data and thermal displacement data of a spindle measured at different time points, establishing a thermal compensation model; a step of, while the machine tool performs a warm-up process, inputting temperature change values measured at least one component of the machine tool at intervals to the thermal compensation model to obtain corresponding thermal-displacement estimated values of the spindle at different time points and changes of thermal displacement values at individual time points; and, a step of, based on the changes of the thermal displacement values at the individual time points, deriving corresponding warm-up completion degrees.
