AI Technical Summary
Traditional composite C-beam parts have difficulty meeting high requirements for assembly surface accuracy, and the carbon fiber matrix under the glass cloth is easily damaged during milling. Parts with large length and large slenderness ratio lack positioning relationships on the milling fixture, resulting in insufficient machining accuracy and stability.
An auxiliary positioning and clamping boss and a detection boss are added to the milling fixture. With the help of special plugs and internal hex bolts, the parts are accurately positioned and fixed. The internal surface accuracy is quickly measured by feeler gauges to ensure the stability and accuracy of the parts during the milling process.
This improved the machining accuracy and quality of the flange surface of composite C-beam parts, ensured the stability of the parts during the milling process, and enabled rapid measurement of the inner surface of the flange.
