Abstract: Aiming at ultrasonic turnmilling progress, a kind of cylinder with multiple diagonal slits with 30 kHz resonant frequency was designed. Using finite element analysis method, the size and the slits position of cylinder with multiple diagonal slits, and mechanical properties were calculated. And the results of finite element analysis were compared with theoretical results. The results of finite element analysis is smaller than theoretical results, because of cylinder with multiple diagonal slits were regarded as ideal model. The impedance analyzer was used to test cylinder with multiple diagonal slits, the deviation and the relative deviation meet the requirements. The experimental results indicate that tested parameters consistent with design results.
