Ultrasound technology is an effective polishing the inner cavity of the mold processing technology , is a the many mold polishing new technology , its research involving electrical theory , control theory , the theory of mechanical dynamics , mechanical design , and other aspects of knowledge . Ultrasonic polishing principle is the use of an ultrasound generator generating ultrasonic vibrations , the vibration transmission through the transducer to the horn , the horn after the vibration amplitude amplifying pass to the abrasive slurry , the abrasive grains in the abrasive slurry to the workpiece surface impact polishing . Inadequacies exist for mold ultrasonic polishing principle and ultrasonic polishing systems research , this paper introduces the research and application , and to carry out the following research : ( 1 ) According to the characteristics of ultrasonic polishing process , established a mathematical model of ultrasonic polishing from theoretically proposed a research methods . ( 2) design the ultrasonic polishing the hardware system , structure and function were elaborated and detailed study and design parameters of the transducer and horn . (3) the critical part of the system designed in detail , mainly to study the ultrasonic generator circuit and the frequency of the tracking control method . ( 4 ) the use of ultrasonic polishing system designed to do a set of artifacts experiments , by the comparison and analysis of the experimental data on the workpiece , the validation of the feasibility of ultrasonic polishing system . Based on the above study and application of ultrasonic polishing , this paper established a mathematical model of ultrasonic polishing , design of the ultrasonic polishing the hardware system , to verify the feasibility of ultrasonic polishing system , rich in theoretical research and application of ultrasonic polishing .
