广东工业大学硕士学位论文AB 广东工业大学硕士学位论文 AB STRACT In production of ceramic file，edging is essentiall operations．There exist shortcomings such large energy consumption、low efficiency and heavy wheel wear in the traditional mechanical grinding，Ultrasonic composite grinding not only retains the characteristics of grinding，but also improve processing efficiency，reduce cutting force，at the same time reduce the cuUing temperature and wheel weal，also Can improve the broken of the tile．Comparative experiments of grinding A1203 ceramics with／without vibration were carried out the he ultrasonic grinding device·In this paper,selecting certain grinding process parameters and grinding modes，comparative experiments were carried out with electroplate diamond wheels．Analytical investigation the grinding force，grinding temperature and broken area of the tile was carried out according to the experimental results First,．According to the motion characteristics of the grinding wheel relative to the workpie，the movement equation of the particle in ultrasonic vibration assisted grinding was established．It analyzes the trajectory of abrasive groins，and plots the track pauern through matlab，combined with the characteristics of ceramic tile edging analyzes the face and peripheral surface of the grinding wheel abrasive movement characteristics．According to the analysis of the movement of the abrasive length and average chip cross·sectional area，it showed that：with the help of ultrasonic motion of the abrasive become longer,chip cross-sectional area getting smaller Second，It introduces and analyzes the overall experimental apparatus．It focuses the specific composition and the main function of ultrasonic power,introduce the structure and size of the the ultrasonic vibration system and improve the mechanical structures．it improve the rigidity and stability effectively Third，the experiment was done about the ultrasonic assisted grinding in ceramic tile．Compared ultrasonic assisted in tile edging and common
