Abstract
The invention is directed to a temperature measuring head for rapidly measuring the temperature of a workpiece on a coordinate measuring apparatus. To rapidly measure the temperature of the workpiece, the coordinate measuring probe element is exchanged for a temperature measuring head which operates pursuant to the principle of a switching probe head. The measuring head supplies a contact signal after contact with the workpiece takes place. From this time point on, the temperature variation is measured by the temperature measuring head and the determined values are stored in the computer of the coordinate measuring apparatus. The temperature of the workpiece is extrapolated via a numerical evaluation method from a specific measurement interval. After the necessary measurement interval, the temperature measuring head is exchanged for the needed probe element combination. The invention is also directed to a temperature measuring head for carrying out the method of the invention.
