Research on an optimized machining method for parallel grinding of f-θ optics

Abstract

Parallel grinding method has been widely used for advanced optics machining, especially f-θ optics. In order to reduce the dependence on high-precision machine tool with many degrees of freedom (DOF) and obtain high machining accuracy, in this paper, we propose a simultaneous 2-axis method to replace the conventional simultaneous 3-axis method in parallel grinding. Firstly, the algorithm of the simultaneous 2-axis method is explained. Then, the motion control errors and machining errors under simultaneous 3-axis and 2-axis methods are comparably analyzed, respectively. Finally, through grinding experiments, the feasibility of the simultaneous 2-axis method is verified.

A Novel Approach to Optimizing Grinding Parameters in the Parallel Grinding Process

“…In fact, it is highly dependent on the grinding modes. Different grinding modes, such as straight surface grinding [28], external cylindrical grinding [29], internal cylindrical grinding [30], self-rotating grinding [31], parallel grinding [32], and cross grinding [33], have different geometrical motion relationships between the grinding wheel and the workpiece. Thus, the surface formation mechanism varies from one grinding mode to another.…”

Investigation on the influence of grinding parameters on surface integrity of substrate in metal additive forging

“…Its highlights performance-oriented reverse manufacturing and IOP Publishing doi:10.1088/1757-899X/1270/1/012041 2 quantitative localized digital manufacturing. Proper grinding parameters are helpful to obtain good grinding quality [15], so as to improve the interface bonding performance, therefore, it is important to study the surface generated by different parameters corresponding to interface bonding performance. To achieve the high-performance manufacturing of heavy forgings, this paper investigated the automatic grinding process of metal additive forging.…”
