Estimating the term…
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.
A temperature measuring head for rapidly measuring the temperature of a workpiece on a coordinate temperature measuring head to the workpiece, the temperature measuring head comprising:
The temperature measuring head of claim 11, said movable part having a lower end and the temperature measuring head further comprising ball joint means on said lower end for holding said sensing means and being movable from a centered first position to a second position wherein said sensing means is deflected with respect to said movable part to facilitate contact with the workpiece.
A temperature measuring arrangement for rapidly measuring the temperature of a workpiece on a coordinate measuring apparatus with the aid of a temperature measuring head applied to the workpiece, the measuring head including switching means for issuing a signal when contact is made with the workpiece, the arrangement comprising:
