Abstract: A machining process and apparatus capable of increasing removal rates achievable when machining titanium and its alloys. The process includes heating a portion of a workpiece with a laser beam, cryogenically cooling a cutting tool with a cryogenic fluid without flowing the cryogenic fluid onto the workpiece, and machining the heated portion of the workpiece with the cutting tool. The apparatus includes a cutting tool, a device for heating a portion of a workpiece with a laser beam prior to being machined with the cutting tool, and a device for cryogenically cooling the cutting tool with a cryogenic fluid without flowing the cryogenic fluid onto the workpiece. The cryogenic fluid is circulated around the cutting tool to achieve a temperature differential between the workpiece and the cutting tool that is capable of improving removal rates and extending tool life at cutting speeds of, for example, above 100 m/min.

Abstract: An integrated laser material processing cell allowing laser-assisted machining to be used in conjunction with directed material deposition in a single setup, achieving greater geometric accuracy and better surface finish than currently possible in existing laser freeform fabrication techniques. The integration of these two processes takes advantage of their common use of laser beam heat to process materials. The cell involves a multi-axis laser-assisted milling machine having a work spindle, a laser emitter, and means for positioning the emitter with respect to the spindle so as to direct a laser beam onto a localized area of a workpiece in proximity to a cutting tool mounted in the spindle. A powder delivery nozzle mounted on the machine and positioned adjacent to the emitter delivers powder to a deposition zone in the path of the beam, such that material deposition and laser-assisted milling may be performed substantially simultaneously in a single workspace.

Abstract: A novel apparatus and method for laser-assisted micro-milling. The disclosed laser-assisted micro-milling system and method provides unique micro-milling capabilities for very difficult-to-machine materials, such as ceramics, high temperature alloys and composites. A low power laser beam is focused at a very small spot, thus producing a very high power density, the spot being located just ahead of a mechanical micro-milling cutter to preheat the material prior to machining. This localized heating thermally weakens the workpiece resulting in lower cutting forces, improved surface finish, and longer tool life. The system is capable of micro-milling difficult-to-machine materials that may be conductive or non-conductive with high material removal rates compared to existing systems and methods.
