厚板冲压是利用厚度≥3毫米的金属板材采用冲压加工成一定形状尺寸,然后部分零件尚需进行切削加工成最终零件。由于应用厚板冲压作为零件毛坯具有省材,机械强度好,加工周期短,生产率高和加工成本低等优点,已越来越广泛地用于各种发动机的加工行业中。目前国外在加工中小型航空发动机中应用较多,特别是对于小型飞机发动机的各机匣安装边,需切削加工的薄壁筒 Thick plate stamping is the use of the thickness of ≥ 3 mm sheet metal stamping into a certain size, and then part of the parts still need to be machined into the final parts. As a result of the application of thick-walled stamping parts as raw material with a saving, good mechanical strength, short processing cycle, high productivity and low processing costs, has been more and more widely used in various engine processing industries. At present, foreign countries in the processing of aero-engine used more, especially for small aircraft engine casing installed on each side, the need for cutting thin-walled tube
