Patent ID: 7021994

Claim:
A method for machining to remove metal from a workpiece, comprising the steps of: 1) providing a holder for a workpiece, 2) providing a metalworking tool having a machining interface configured to engage the workpiece along the machining interface to remove metal from the workpiece, 3) cooling the metalworking interface by emitting a stream of a cooling liquid through a nozzle body having a flow passage with an inlet and an outlet, and a bore having an access opening in fluid communication with the flow passage and a line of sight with the flow passage outlet, wherein the access opening is sealed by a removable plug, wherein prior to the machining, the plug is removed from the bore and a visible laser is inserted into the bore for emitting a laser beam that cooperates with the nozzle body for visually positioning the nozzle relative to the metalworking tool, whereby the emitted stream of cooling liquid is directed at the machining interface.
