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.

Smart coolant pump

A method and apparatus for controlling a continuous machining process includes a robot, a machining tool, a table, and a raw parts supply mounted inside a machining cell enclosure. The table has first and second vises for holding parts. The machining tool is operated to machine a raw part in one of the vises while the robot is operated to pick a machined part from the other vise and then place another raw part into the other vise. The table can be fixed or rotatable. The robot places the picked machined parts on an exit conveyor to remove the machined parts from the enclosure.
