In order to solve the problem of machining micro-sized parts with complex shapes, a micro-blanking device is designed, which makes use of the characteristic that the output displacement of piezoelectric ceramics changes when the input voltage changes. The simulation analysis of micro internal gear blanking was completed by deform software, and the ideal internal gear parts were obtained. When the piezoelectric ceramics are deformed, a great driving load can be generated, and finally the micro internal gear parts are machined on the designed device. Compared with other equipment used for machining such parts, the designed device has the characteristics of good machining performance, low cost and high control precision.

为了解决形状复杂的微型零件的加工问题，利用压电陶瓷的输出位移随输入电压变化而变化的特性，设计了一种微冲裁装置。通过变形软件完成了微内齿轮冲裁的仿真分析，得到了理想的内齿轮零件。当压电陶瓷变形时，会产生很大的驱动载荷，最后在设计的装置上加工出微型内齿轮零件。与用于加工此类零件的其他设备相比，所设计的装置具有加工性能好、成本低、控制精度高等特点。
