Machine Monitoring Systems for milling machine
The milling machine sector, like the rest of the machine tool sector, is in continual technological evolution. The demand for large numbers of increasingly precise and repetitive parts, together with the need to save time, means that the manufacturer needs to implement machining systems capable of rendering the process as reliable as possible, even when not monitored by an operator.
Conditions:
Temperature variation can cause geometric variations in spindle components, resulting in flaws during the machining process - especially high precision processes (e.g. when manufacturing aeroplane turbine blades).
Furthermore, vibrations produced during the machining processes can exert excessive stress on the spindle bearings and may damage or break them. The spindle may also be seriously damaged as the result of accidental collisions/impacts during ordinary, daily operation.
Solution:
Since 2004 Marposs is offering several solutions for Tool and Machine Monitoring. Since 2008 trough the acquisition of a market leader of this sector like Artis, Marposs can surely offer the most complete product range in this field of action.
Marposs offers a highly accurate system with a non-contact sensor to correct the effects of drift, caused mainly by variations in spindle temperature (spindle growth). This system provide accurate, extremely high resolution measurements of variations in the size of the spindle.
Marposs MMS line also includes a wide range of systems and sensors for controlling vibration, collision and monitoring the tool during the machining process. In particular, the latter are capable of providing an indication of the tool state either indirectly by measuring the current drawn by the motors, or directly by measuring the actual cutting force. Moreover, a pure software solution for tool monitoring is available for machine tools based on a SIEMENS 840D NC as well as a Windows based industrial PC with preinstalled operating software is provided for those applications for which is requested a separate visualization, apart from the machine human interface.
Benefits:
- Improved product quality
- Vibration level control during machining process
- Maximised tool exploitation
- Reduced rejects
- Unsupervised machining cycles (e.g. Lights-out)
