Sensorised CNC tool holder

In many production processes, CNC machining centres use specific tools to perform tasks such as drilling, cutting, polishing, edging, etc. These tools are connected to the machining centre via a tool holder. The tool holders do not carry a sensor that enables us to detect the performance and interaction with the part being machined. This lack of information makes it difficult to optimise the processes that are being carried out.

At Nazca we have an operational prototype that allows the following parameters to be monitored both in real time and wirelessly:

• Torque
• Bending
• Shear
• Revolutions per minute
• Axial force
• Operating temperature

Monitoring could allow process optimization with the following benefits:

• Reduced processing times
• Improve the quality of the process performed
• Determine the possible failure in real time, thus avoiding more serious problems and stopping a process that will result in a part that does not meet the required quality standards.
• Extending the operational life of the tool
