Design of Mechanical Processing Technology for a High Hardness Complex Thin-walled Wing
Currently,there was no high-speed milling method available for a high hardness complex thin-walled wing,which required a combination of ordinary milling and vacuum treatment to meet the technical requirements of the product,so the processing difficulty was high,and the production schedule was tight.Through process research and optimization,it was formed that a mechanical machining process plan for the wing.By using the method of vacuum furnace quenching after ordinary milling,the angle,thickness,aperture,and mechanical performance requirements of the wing were ensured.Final-ly,the workpiece was separated from the process table by electric discharge cutting to ensure the distance between the wing shaft holes and the external dimensions.By combining the characteristics of vacuum furnace treatment and electric discharge cutting,technical problems such as heat treatment deformation and cutting shape that causing hole pitch deviation during the processing were promptly addressed,ultimately ensured the delivery of the first batch of qualified products on schedule.The wing process scheme,process table,positioning reference selection,tooling for controlling heat treatment deformation,and electrical discharge cutting tooling involved were the first applications within Xi'an Modern Control Technology Research In-stitute,which were innovative and had certain reference value for wings with high technical requirements in missile structur-al components and components of similar structures.
