Tool Condition Monitoring System
Using Acoustic Wave (Acoustic Emission)


Acoustic emission technology is used on machine tool condition monitoring or cutting tool condition monitoring. The RAEM2 wireless tool condition monitoring system can extends tool life and eliminates workpiece damage caused by tool wear.

In the process of turning, milling, grinding, punching, drilling and more cutting tool machinery, there may be plastic deformation of the workpiece, wear caused by the friction between the tool and the workpiece or chip, chip fracture and tool fracture.

The acoustic signal from the machining process reflects the tool wear condition. The monitoring system receives the acoustic signal and analyzes the tool wear condition.

Application Results

  • All year round of online monitoring and detection
  • The whole process of automatic analysis results
  • Internet of Things remote operation and use
  • Real-time mobile phone alarm notifications

Main Hardware and Software Introduction

RAEM2 series Remote Acoustic Emission Monitoring System consists of:

  • RAEM2
    • Sensor
    • Acquisition
    • Communication modules
  • Cloud platform
  • Client terminals

1.1 Sensor

W500, GI40 or GI150 series sensors can be used. AE sensors can convert acoustic waves mechanical signals into electrical signals and transmit signals to acoustic emission acquisition and analysis system.

1.2 RAEM2

RAEM2 AE system integrates sensor, acquisition board, data communication (Bluetooth, etc.) and battery power supply.

1.3 Cloud platform

Qingcheng IoT cloud platform, Ali Cloud platform, Amazon cloud platform, etc.

Real-time data display: users can carry out remote monitoring through the cloud platform and the cloud platform can push alarm information to users automatically when the device is abnormal.

1.4 Bluetooth App Patrol

This system supports onsite inspection by connecting devices with smart phone via Bluetooth for device Settings and data monitoring.
