Abstract: A method for fabricating a component using a tool includes determining an actual property of a region of the component, comparing the actual property of the region of the component with an expected property of the region to determine a difference between the actual property and the expected property, and updating a path of the tool that is electronically stored in a memory and executable by a processor for fabricating the component based on the difference between the actual property and the expected property of the region.

Abstract: A metal machining apparatus for removal of metal from a workpiece, that employs a laser-targeted coolant nozzle to apply coolant fluid to a machining tool, such as a grinding wheel, to remove metal from a workpiece. The laser-targeted coolant nozzle has a coolant nozzle body having a flow passage for the coolant fluid, and a laser bore through which a visible laser can be inserted. The visible laser cooperates with a positioning feature on the nozzle body for visually positioning the coolant nozzle relative to the grinding wheel. When the laser is removed and replaced with a seal plug, the stream of cooling fluid passing through the flow passage can be directed accurately at the grinding wheel for improved workpiece grinding.

Abstract: A manufacturing cell having a plurality of work stations, where at least one of the work station comprises a metalworking machine, and where at least one metalworking machine is provided with a modular tooling apparatus. The modular tooling apparatus consists of a base having one or more attachment surfaces, and one or more inserts that can be inserted semi-permanently to the attachment surfaces. The attachment surface is typically a pocket in the surface of the base. The insert has a workpiece support feature that can support and/or secure the workpiece into the proper position and orientation for machining. The base, pockets and inserts are configured to provide a characteristic location and orientation for the workpiece relative to the base, and to the metalworking machine.

Abstract: A modular tooling apparatus for performing a metalworking operation on a workpiece or a family of workpieces. The modular tooling apparatus consists of a base having one or more attachment surfaces, and one or more inserts that can be inserted semi-permanently to the attachment surfaces. The attachment surface is typically a pocket in the surface of the base. The insert has a workpiece support feature that can support and/or secure the workpiece into the proper position and orientation for machining. The base, pockets and inserts are configured to provide a characteristic location and orientation for the workpiece relative to the base, and to the metalworking machine. The modular tooling apparatus permits machining a family of workpiece members that are related but different in detail, by inserting the insert member from the family of inserts to properly position and orient the corresponding workpiece member, without needing to change, disconnect, or move the base tooling.

Abstract: A metal machining apparatus for removal of metal from a workpiece, that employs a laser-targeted coolant nozzle to apply coolant fluid to a machining tool, such as a grinding wheel, to remove metal from a workpiece. The laser-targeted coolant nozzle has a coolant nozzle body having a flow passage for the coolant fluid, and a laser bore. The laser bore forms an access opening in the outer surface of the nozzle body in through which a visible laser can be inserted. The laser bore provides a line of sight with the flow passage outlet. The visible laser can be inserted into the laser bore, and is configured so that the visible laser beam cooperates with a positioning feature on the nozzle body for visually positioning the coolant nozzle relative to the grinding wheel. When the laser is removed and replaced with a seal plug, the stream of cooling fluid passing through the flow passage can be directed accurately at the grinding wheel for improved workpiece grinding.

Abstract: A host computer is connected to one or more machining workstations, each having its own electronic controller. Each workstation controller contains an operating machine control logic module which controls the functioning of the workstation, such as the carrying out of the movement of a chuck holding a workpiece to be machined on a spindle with respect to a tool which does the machining. Each workstation controller also contains an automation machine control logic module which automates the operation of each of the workstations.

Abstract: In the present invention, the breakage of a cutting tool is sensed during a cutting operation of stock on a lathe. A boundary is defined around the stock. The cutting tool is withdrawn stepwise along the same path taken up to the point of breakage. After each step, inquiry is made as to whether the tool has crossed the boundary. When it does, the tool is brought directly to a tool changing station without further stepwise withdrawal.
