Collision monitoring transducer connects to PLC
- Published: September 7, 2017
Marposs' new standalone Artis VM-02 features a MEMS or three axis piezoelectric monitoring sensor that measures in-process machine tool acceleration values, helping to minimize damages after a dynamic crash.
Part of the Genior Modular machine monitoring system family, the VM-02 is a low cost, upgradeable solution with an ultra-fast reaction time (<1 millisecond), says the company.
Through a 24V discrete IO communication protocol, the VM-02 can be easily integrated into any machine tool and CNC control to mitigate machine damage, repair cost and downtime caused by dynamic collisions created by human mistakes (set up), errors in the NC program, machine operation, etc.
Users load the VM-02 software onto a Windows based computer, and the system then registers and documents exact identification of collision events as any unacceptable vibrations occur in the machine or tool. There are three different modes available for machine setting and acceleration measurement is provided in three axes and three windows. The transducer is designed for simple installation into the existing machine electrical cabinet. Three possible Fast Output alarms are available: Hard Stop, Soft Stop and Warning Limits can be set up for each axis.
As part of the Genior Modular tool and process monitoring systems, the VM-02 can be installed alone or by connecting the GEM CPU module to the VM-02 enabling mechanical vibrations (RMS or mm/s) to be measured during the cutting process in addition to the acceleration monitoring (g). With this configuration, additional measurement transducers can be added to monitor up to eight simultaneous process signals from the cutting such as force-strain, acoustic emission, true power, and torque, as well as FFT analysis, etc. The Genior system is a comprehensive, fully automatic solution with multi-sensor and multi-screen visualization capability to effectively monitor the machine, spindles, axis, and the tool to optimize the cutting process.
