Omative Systems North America will debut at IMTS 2014 its proprietary, software-based systems for adaptive machining, real-time vibration monitoring and shop floor production management.
Omative's ACM Adaptive Feed Rate Control is designed to reduce cycle time and protect the cutting process by monitoring the load and making real-time adjustments to the programmed feedrate. ACM runs a test on the first workpiece and "learns" the maximum spindle load for each operation. The user then sets an allowable override of the programmed feedrate, and from there ACM adjusts the feedrate for maximum efficiency based on the learned load value. When cutting conditions are lighter, feedrate is increased and cycle time reduced. Where the load becomes heavier due to unexpected workpiece hardness or thickness, the system reduces the feed, even to below the programmed rate, to protect the cutting tools and workpiece. ACM automatically increases the feedrate to maximum during air cutting, then pauses and lowers the feed immediately prior to entering the material. "In real-world applications, ACM has reduced cycle times by 20% and more, depending on the application," said a company spokesperson.
ACM is also designed to prolong grinding wheel life by dynamically adjusting the feedrate to compensate for ongoing wear. The software can be installed on almost any CNC, including Siemens, FANUC, Heidenhain and others, and receives all its inputs from the controller without the need for external sensors.
Omative VCM Vibration Monitor constantly compares machine and tool vibration against healthy baseline signatures, and issues alerts or shuts off the machine as instructed when values are exceeded. VCM reacts instantly to extreme events, such as collisions. After a collision, it can indicate whether there is internal damage. It also alerts the user to gradual changes in vibration that suggest maintenance is necessary. At the tool level, VCM can recognize broken tools, missing tools or improperly mounted tools, or even changes as small as a broken insert on a face mill - critical for companies considering lights out production.
Omative PRO Shop Floor Management software is designed for optimizing processes and OEE. It reports machine performance data to remote computers from any CNC running ACM. It provides real-time, graphical information on machine availability, cycle times, cutting tool performance, alarms, cycle time saving from ACM, parts production and other data. According to the company, the software works seamlessly with any CNC where ACM is installed.
