Title:
MACHINE TOOL AND DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/063583
Kind Code:
A3
Abstract:
The invention relates to a machine tool having a driveable tool and having a detection system for detecting contact between the tool and a user. The detection system has an excitation device for applying an excitation voltage signal to the tool, a current sensor for generating a current sensor signal that represents an electric current consumed by the tool, and a processing device for processing the current sensor signal in order to detect contact between the tool and the user. The processing device has an analogue-to-digital converter and further devices arranged downstream of the analogue-to-digital converter, comprising an IQ demodulator, a filter device and an evaluation device. The current sensor signal is able to be digitized using the analogue-to-digital converter and processed in digital form using the further devices. The invention furthermore relates to a detection system for a machine tool.
