The parameter selection of laser-cut quartz crystal is the primary task of laser cutting quartz crystal. Based on the parametric model of laser-cut quartz crystal, the basic rules affecting the quality of laser-cut quartz crystal are theoretically analyzed, which is reasonable choice in the actual production process. Laser power and cutting speed provide a theoretical basis. Wire EDM has a marked asynchronous relationship. It is not only required to correspond to the starting and ending points of the upper and lower trajectories of the straight lines, but also to require strict correspondence between several points in the middle. Synchronization relationship. When the number of upper and lower trajectory geometric segments of the ruled surface is equal, and each geometric segment is required to correspond to each other, that is, each base point of the upper and lower trajectories is in one-to-one correspondence. In fact, in this case, the workpiece should also be considered to consist of many small ruled faces. The corresponding points of each base point of the synchronization relationship are known, and the trajectory synthesis calculation can be directly performed without marking. For the four-axis linkage CNC machining, due to the complexity of the circular interpolation calculation and the projection of the upper and lower trajectories of the workpiece to cause the distortion of the geometric segment, it is generally required that the automatic programming system linearizes the upper and lower trajectories of the workpiece and obtains the linearity. After the corresponding point coordinates of the node, the linear four-axis linkage NC program is obtained. The corresponding straight line and arc or arc and arc are represented by the parameter equation of the same parameter t, and the two corresponding points having the same parameter value are connected one by one by straight line segments, thus forming a ruled surface.
