摘要： A method and apparatus for automatically cooling a workpiece being manufactured by shape melting whereby a gas/liquid coolant mixture is pumped onto the external surface of the part to be cooled. Temperature and pressure data is fed to a computer control system which regulates the flow of the gas and liquid coolant mixtures. A suction device which enshrouds the spray head extracts the heated and vaporized fluid from the vicinity of the surface. The apparatus may be provided with multiple spray heads which comprise the cooling head and have the ability to control the total rate at which coolant flows through the device by individually controlling coolant and gas flow through each of the multiple spray heads. If more cooling is desired, the computer control system activates more nozzles for flow, or it increases flow rate through already activated nozzles. Both the number of spraying heads and flow rates through each spray head are variable, so the cooling capabilities of the system are continuously variable over a wide range of total flow rates through the device.

摘要： A dressing-grinding process for electronically controlled grinding machines for plain or surface grinding of workpieces is described. In order to maintain the effective rough depth during the grinding process, while the roller RPM must be selective and the feed of the dressing roller against the grinding wheel must be continuous, the dressing roller carrier is continuously fed against the grinding wheel carrier in accordance with the functions ##EQU1## wherein is: v.sub.frd (t): feed speed of the dressing roller carrier slide (31) relative to the grinding wheel slidea.sub.ed (t): dressing feed per revolutionn.sub.s (t): grinding wheel revolutionsd.sub.s (t): grinding wheel diametert: current timev.sub.s : grinding wheel circumferential speed; for the described example of a straight grinding wheel it equals the grinding wheel speed v.sub.c. Thus v.sub.c =v.sub.s.y.sub.s (t): vertical coordinate of the wheel centery.sub.x (t): workpiece dimension in y direction.

摘要： A programmable coolant nozzle system includes a coolant fluid nozzle fixed to a manifold so that the centerline of the nozzle and the centerline of the manifold block are perpendicular. This feature allows coolant fluid to be rotatably directed from the nozzle at great pressure and/or volume with an actuator that does not have to withstand severe tortional force. The invention includes a method which allows coolant fluid to be rotatably directed from a nozzle assembly and to be commensurate with any change in position of the working tool of a machine tool center.
