| 摘要 |
The invention proposes a manufacturing assistance device and a tool apparatus (1) comprising a processing tool for processing a workpiece and comprising an ultrasonic position finding unit for ultrasonic position finding for a manufacturing assistance device by determining at least one distance between an ultrasonic transmitter (4, 5, 6, 7) and an ultrasonic receiver by means of time-of-flight measurement of an ultrasonic measurement signal, wherein a transmitting unit (2) comprises at least two ultrasonic transmitters arranged on a straight line (8, 9), wherein the processing tool has a processing longitudinal axis (11), said apparatus/device requiring less outlay and achieving, in particular, more precise position finding and/or manufacture. This is realized by virtue of the fact that the straight line (8, 9) of the transmitting unit (2) and the processing longitudinal axis (11) have a common intersection point (10). |
