Abstract: A thermal displacement correction apparatus for a machine tool first determines the coefficient k in E=a+k|F| where F is a thermal displacement correction amount and E is an adjustment value (first step). Next, in actual processing, a is set if a has not been set yet (second step). After a and the coefficient k are determined in advance, thermal displacement correction unit is enabled and an operation of a machining program is started. The thermal displacement correction amount F is calculated, the adjustment value E is calculated based on E=a+k|F|, a thermal displacement correction amount F′ after adjustment (=E×F) is calculated, and F′ is sent to the thermal displacement correction unit.

Abstract: A machine tool management system connects an external server and a large number of NC devices controlling the external server and respective machine tools through a network. The system collects several kinds of signal data from the NC device of each machine tool to the external server. In the system, the external server collects an estimated thermal distortion from the NC device and compares the estimated thermal distortion with pre-stored data to determine whether the tool is machining favorably.
