OMATIVE’s Vibration Control Monitor (VCM) is a suite of in-process solutions for the acute vibration-related problems in CNC metal cutting machines. By applying sophisticated real-time diagnostic methods, VCM anticipates and avoids vibration related events that cause machine breakdown.
VCM is a cost effective, real-time system that monitors machine tool vibrations and reduces the risk of breakdowns and diminishes production disruptions and the resulting production inefficiencies. By monitoring machine vibrations, VCM protects, not just the machine itself, but also other components of the machine tool system, including machined parts, cutting tools, fixtures, machine spindle, bearings and axes motors.
In addition to displaying many different facets of the vibration spectrum in real time, VCM issues warnings and/or stops the machine if unacceptable conditions occur -- thus preventing failures.
Tool-Specific Vibration Monitoring -- Recognizing different vibration behaviors of various tools, VCM can automatically prevent excessive vibrations for each tool by performing process monitoring on the basis of tool-specific vibration analysis. Tool-specific vibration monitoring is carried out in both time and frequency domains.
Collision Detection -- VCM performs an Emergency Stop in response to the collision of any machine tool components, such as machine spindle, tool, machine table, etc.
VCM displays raw acceleration signal in the time-domain
Vibration Signature Analysis -- VCM compares the machine’s current vibration signature against its "reference" vibration signature, recorded when in "healthy" condition, enabling users to take preventive maintenance action.
Post-Failure Vibration Analysis -- VCM continuously records the machine’s vibration history, providing machine footprint information to operate as a "black box", thus enabling post-failure vibration analysis. This function can help supervisors to learn about incorrect operating practices.
Spindle Lifetime Histogram -- VCM continuously captures spindle load, speed and vibration data, to build a histogram of the spindle's lifetime usage. Based on this histogram, it can calculate a factor which can truely represent the spindle's actual condition.
VCM configuration:
Data Acquisition Unit - a microcontroller based industrial controller for vibration signal processing.
Vibration sensor(s) - Up to 3 single-axis industrial IEPE or one three-axial accelerometers can be mounted on the machine and connected to each Data Acquisition Unit.
VCMSoft - Windows based software integrated into the CNC's HMI.
