Verfahren zur Korrektur thermischer Verschiebung in einer Werkzeugmaschine |
摘要 |
In a machine tool controlled by using a numerical control device, a correction amount is determined for thermal displacement due to heat generation and heat conduction in a spindle motor and a feed shaft motor, in addition to thermal displacement due to heat generated by rotation of a spindle and a feed shaft. A tool position is corrected based on the correction amount. An entire stroke of the feed shaft is divided into a finite number of sections, and for each section, a correction amount for thermal displacement due to axial movement of the feed shaft is determined. The tool position is corrected based on the determined correction amount. |
