Abstract:
A smart coolant pump for a robotic or computer-controlled machine. The smart pump uses a servo motor rather than a conventional industrial motor such as an induction motor. The smart pump has inherent torque and speed sensing, and a controller integrated with the computer-controlled machine controller. The motor torque/speed sensing and coolant pressure/flow sensing enable immediate detection of any anomalous conditions such as low coolant level or coolant port blockage. The smart pump can be configured to run at a certain speed and provide a specific coolant pressure and flow rate for each machining operation performed at the station, and to run at a very low speed between machining operations. This speed configurability saves energy and allows the pump and coolant to run at lower temperatures compared to conventional constant-speed coolant pumps.
