Embodiment Construction
[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings of the description.
[0015] A tooling for ordinary three-axis milling and cutting carbon fiber composite long beam structural parts, including a base groove, an inner module and an outer module. The base groove is welded by 4 steel plates and has a U-shaped structure. One piece, the top and bottom of the bottom are milled and flattened as the reference plane; bolt holes are provided on the side, and the foundation groove and the inner and outer modules are pressed by bolts.
[0016] A method for common three-axis milling carbon fiber composite long beam structural parts, the following steps are taken:
[0017] Step 1: Take the net cutting line of part 1 as the reference, level the probe and draw the cutting line;
[0018] Step 2: Place the base groove 2 on the processing table with guide rails of the three-axis CNC machine tool;
[0019] Step 3: fix part 1 th...

The invention discloses a method for cutting a carbon fiber composite long beam structural part through a common three-axis milling machine. The following steps are adopted that firstly, the net cutting line of a part serves as the benchmark, and the cutting line is leveled and marked off through a probe; secondly, the part is clamped and fixed through a tool; thirdly, pouring glue is poured intoa base groove, and curing is conducted for 3 h to 5 h at the normal temperature; and fourthly, part trimming and drilling are conducted, wherein the allowance of 1 mm is reserved after rough machiningis adopted for trimming, finish machining is conducted in two times, the feeding speed is controlled to be below 40 mm / min, and drilling is conducted after trimming is completed. By the adoption of the method, the common three-axis milling machine is adopted, the requirement for part machining can also be met, a common three-axis numerical control milling manner is adopted as an economical and feasible composite machining manner for the part benchmark, part clamping and the part, and the machining cost is greatly reduced.
Description
technical field [0001] The invention relates to a processing method for structural parts in the field of aviation manufacturing, in particular to a method for milling carbon fiber composite long beam structural parts on a common three-axis machine tool. Background technique [0002] There are currently two ways of mechanical processing of composite structural parts: manual processing and mechanical processing. Manual processing generally uses diamond grinding wheel cutting or sawing. This processing method needs to control the feed speed well so as not to overload the grinding wheel or If the workpiece is overheated, a backing plate should be used at the outlet end of the grinding wheel to support it to prevent splitting. The pass rate of parts processed by manual cutting is low, and it is difficult to meet the needs of batch production. CNC milling is a common mechanical processing method with high efficiency and a high pass rate of parts, which can well meet the quality r...
