Abstract

The invention relates to a method for machining a special-shaped hole by ultrasonic impact. In the process of machining, the workpiece to be processed is processed by the first feed pressure. When the remaining processing amount W of the workpiece to be processed is 1 When the preset value is reached, stop the special-shaped tool head and continue to move down, maintain the relative position of the ultrasonic transducer, horn and special-shaped tool head and the workpiece to be processed, and use the mechanical energy of the end surface of the special-shaped tool head to make the abrasive continue to impact the workpiece to be processed The workpiece, until the exit of the special-shaped hole is processed on the workpiece to be processed, forming a special-shaped hole passing through the workpiece to be processed, which can effectively avoid edge collapse at the exit of the special-shaped hole.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a method for machining special-shaped holes by ultrasonic impact. Background technique [0002] Ultrasonic machining is a forming method that uses ultrasonic vibration of the end face of the tool head to process hard and brittle materials through abrasive suspension. Suitable for processing hard and brittle materials with superior physical, chemical and mechanical properties such as optical glass, ceramics and silicon carbide. [0003] When ultrasonic processing is used, a suspension mixed with liquid and abrasive is added between the tool head and the workpiece, and pressure is applied in the vibration direction of the tool head. The ultrasonic frequency electric oscillation generated by the ultrasonic generator is converted into ultrasonic vibration through the ultrasonic transducer Frequency mechanical vibration, the horn will amplify the amplitude and then transmit it to t...
