A 2-Dimension Simulation Model for the Beveling of Quartz Crystal Blanks

The shape of quartz blanks has a significant effect on the electrical performance of the quartz crystal resonators. In order to obtain a better electrical performance, the beveled blanks with thinner edge are always required. The beveling shape is mainly determined by the beveling barrels, but yet there is no study on the 2-dimension model for the beveling process to provide references for the beveling barrel design. In this paper, a difference equation model for the variation of 2-dimension surface formed during the bevel process is developed, based on the study of the geometrical relationship between the blank and the barrel’s internal face, and the study of the characteristics of the material removal rate. Finally, the simulation model is validated by experiment under different conditions of beveling barrel.
