Research on Application of Three Dimensional Laser Cutting Technique in Chemical Milling and Welding Case

Through analyzing the chemical milling structure of the titanium alloy welded case,the chemical milling process was designed.Since the plate making quality plays a key role in the chemical milling process,a laser engraved scheme for chemical milling graphics plate was determined.With general three-dimensional laser cutting machine as engraved type machining equipment the technical problems in the process of laser engraving were analyzed,and the group-based programming was adopted to solve the error problems of flexible cutting trajectory of a common carved three-dimensional laser.Finally the optimal cutting parameters were selected through laser engraved test with multiple parameters,so that the laser engraving before chemical milling was completed.The method of flexible and accurate engraving for chemical milling graphic is achieved by general three-dimensional laser cutting machine,which has some reference value in selecting preparation scheme for chemical milling graphics engraving of complex structural parts.
