摘要： A unitary adapter for attaching a cutting nozzle to a laser cutting head includes an inner cylinder made of ceramic, a conductive shield sintered to the outer sidewall of the ceramic cylinder, a threaded conductive holder (for accepting the cutting nozzle) mounted in an opening at one end of the ceramic cylinder, and a coaxial connector (for connection to external measuring equipment) attached to an opposite end of the ceramic cylinder. A pair of wires is formed to be embedded within the ceramic material and provide separate electrical connections between the coaxial connector and: (1) the threaded holder, and (2) the conductive shield. The various components are sintered to the ceramic body to form permanent attachments, creating a unitary structure less susceptible to the high levels of acceleration and elevated temperatures associated with the laser cutting process.

摘要： Disclosed techniques compensate for variable forces applied to a brazing head in order to more accurately maintain application of a desired lateral force by a brazing wire, filling wire or tracking finger extending from the brazing head to a component. Orientation of the brazing head is determined relative to gravity and the angle of a movable arm of the brazing head relative to a support body of the brazing head. A lateral force value measured by a lateral force sensor is adjustable based on the determined orientation of the brazing head and the determined angle of the arm relative to the support body in order to provide a corrected or adjusted lateral force value. At least a portion of the brazing head is repositioned relative to the component if the corrected lateral force value deviates from a predetermined value.
