Adaptive Machining Implementation

ACM optimizes cutting performance by measuring cutting torque in real-time and automatically adjusting cutting speed to maximize cutting efficiency. The monitoring function can trigger alarms and notify the operator in case of abnormalities. This approach boosts productivity extends machine and tool life and ensures a stable production process. For this project we used Siemens software in order to optimize our cutting time and tool life. Our CNC machine used a FANUC controller. This meant that we had to hard-wire independent sensors to each motor (see axis diagram). The sensors could then indicate a learned torque/amperage applied to each tool. If any tooling loads exceeded this learned value by 15% an alert would be sent. After 20% a feed hold M-code would be generated in order to protect the machine spindles/tools.
