Ultrasonic grinding miniature female mold machining method based on mold dielectrophoresis effect

Abstract

The invention provides an ultrasonic grinding miniature female mold machining method based on the dielectrophoresis effect. Grinding balls and a workpiece to the machined are located in grinding liquid. A first electrode plate is installed on a substrate and connected with a first leading-out end of an alternating-current power source. A second electrode plate is installed on a locating plate and connected with a second leading-out end of the alternating-current power source. The voltage input end of the alternating-current power source is connected with a frequency and voltage adjusting controller which is used for controlling the voltage and the frequency of the alternating-current power source. After an ultrasonic wave generator emits ultrasonic waves, audio frequency electric oscillation of input ultrasonic waves are converted into mechanical oscillation through an energy converter, the ultrasonic oscillation is transmitted to an oscillation rod, the oscillation rod is made to vertically oscillate, oscillation generated by the oscillation rod is transmitted to an oscillation plate, oscillation is transmitted to the grinding balls on the locating plate through the oscillation plate, oscillation generated by the grinding balls can rapidly impact grinding particles and grinding materials in the grinding liquid, and then a needed female mold can be generated on the workpiece. By the adoption of the ultrasonic grinding miniature female mold machining method, through the dielectrophoresis force, the staying time of the grinding particles and the grinding liquid in a machining area is prolonged, the number of the grinding particles is increased, the machining precision and the machining efficiency are both considered, the machining consistency is good, and the control mode of a machining mode is simplified.
