Process and quality monitoring

The process monitoring happens during the machining

The system
Due to the integrated measuring and evaluation system the process parameters are analyzed during the machining, what gives the possibility to automatically intervene in the process before the part or tool gets damaged.

The process optimization
Cutting speed and parameter optimization
Cutting oil and tool optimization
Tool life optimization
Cycle time optimization
Process analysis

Profits
No additional monitoring system necessary
Detection of errors and deficiencies
Higher productivity
Shorter cycle times
Reduction of material rejects
Tool protection
Lower tool wear
Process evaluation
Quality assurance
Reduction of costs

Examples: Process deviation and error during the machining.

Monitoring of the maximum torque is always active to protect the tool.
The minimum torque is optional adjustable.
Additional parameters are evaluated in combination with the torque, i.e.: Depth, time, feed orientation etc.

The torque is visualized as arrow around the tapping tool:

green correct torque
blue torque too low
red torque too high or error
