Overview: The document describes the Acoustical Emission Monitoring System (AEMS) used for controlling grinding gaps and detecting crashes in machinery. The AEMS card is installed in the SB-4500 series controller and utilizes a sensor for monitoring.
Features:- Fast acoustical emission measurements with high sensitivity over 100db.
- Detection and reporting capabilities of less than 1.0 msec.
- Menu-driven keypad interface and screen graphics for result monitoring.
- Separate modes for grinding and dressing.
- Combines analog and digital technologies for ease of operation and fast measurements.
Benefits:- Quick and easy setups, saving man-hours.
- Measures efficiency during grinding.
- Fully automated CNC sensing and display.
- Affordable 100% monitoring and easy retrofit to existing machines.
- Improves dressing quality and reduces costs.
- Prevents machine and part damage.
- Includes 8 separate, 6th order Butterworth filters for optimal signal detection.
Specifications:- Two sensor signal inputs available, selectable based on operating mode (grind/dress).
- Acoustic range greater than 120 db.
- Frequency range from 50 KHz to 950 KHz with several filter ranges.
- Filter staging includes 8 specific frequency ranges from 50-950 kHz.
- AE repeatability of ±2% and reproducibility of ±5% at 50:1 signal to noise ratio.
System Overview: The AEMS system includes sensor selection, filter settings, gain settings, range settings, and sensitivity settings. It features a microprocessor control, display, signal controller, and graphic output.
Filter Response: The document includes a graph showing the relative amplitude response of the AEMS filters across various frequencies, indicating the system's filtering capabilities.
