AI Technical Summary

Technical Problem

Conventional cutting tools face challenges in continuous monitoring of the cutting tool's state during long machining operations due to battery depletion, and existing wireless power solutions risk radio wave leakage that interferes with sensor output transmission.

Method used

A cutting system with a shielding member attached to the machine tool's cover window, featuring a shielding body to block radio waves and a communication antenna to enable wireless communication, allowing sensor output to be transmitted externally while minimizing wave leakage.

Benefits of technology

The system effectively suppresses radio wave leakage from the machining space while enabling continuous monitoring of the cutting tool's state by transmitting sensor output externally.

Abstract

A cutting system according to an embodiment of the present disclosure includes a cutting tool having a tool body disposed in a machining space of a machine tool, a sensor provided on the tool body, and a wireless communication unit that transmits an output of the sensor, a power feeding device that wirelessly feeds power to the cutting tool in the machining space, and a shielding member attached to a window portion of a cover that defines the machining space. The shielding member includes a shielding body that shields radio waves radiated into the machining space and a communication antenna for communicating with the wireless communication unit.
