Tool and Process Monitoring System

CTM is the excellent monitoring system, that has led the market leader for almost 25 years.

The CTMCPU successfully optimizes in real time, tool and the process of CNC machining in metal-cutting production. This means that without interfering with production or adding cycle time the system is supervising the machine. It delivers a wide range of monitoring functions for most production scenarios in real time. The flexible interface concept of the CTMCPU enables problem-free integration: from solutions with no fieldbus connections (dedicated I/O), to branched data and fieldbus architectures. The CTMCPU is designed for easy integration into dedicated operator panels with Ethernet connection of WINDOWS based controls (SIEMENS PCU50, FANUC Panel i, MTX, etc.). Alternately, if needed, a stand-alone unit with significant flexibility can be used in all other machine types with different controls or in machines without CNC. Again, because of the flexibility many user specifications (e.g., from the aerospace and automotive industries) can be met by implementing the CTMCPU with different monitoring strategies.

For mass production, the teach-in values (learning curves) are commonly used to compare them with actual values. The required limits can be set exactly to suit the application by means of corresponding process parameters. Long cutting cycles can be monitored best by either using the dx/dt monitoring strategy or a strategy mix.

All monitoring data can be stored locally on the machine or in the network/internet. In addition, the system provides functions for customized reports and data analysis in order to further improve the corresponding processes. With these functions, users can extend tool life, reduce waste, avoid tool breakage, and minimize machine downtimes.

The process monitoring works with either fixed or dynamic alarm limits, depending on the operating mode.
