Research on Technology of Fluid-Impact Fatigue Fracture Deburring Based on Industrial Robot

In this paper, a flexible machining system which combines fluid impact deburring technology and robot control technology is discussed. For the purpose of solving the problem caused by burrs in the horizontal hole, a method named fluid-impact fatigue fracture deburring is put forward in this paper in order to remove burrs. The first four orders of inherent frequency, vibration mode characteristics and stress frequency response diagram of burrs are obtained through further modal analysis and harmonic response analysis on such burrs. Finally, the resonance frequency of burrs can be calculated. Through comparative analysis on situation of burrs before and after deburring test, feasibility of this method is verified, which provides a reliable theoretical basis for removing burrs on automobile brake master cylinder.
