The design of chisel-edge ruling tool for diffraction gratings

The process of parameters design on chisel-edge ruling tool of diffraction grating, which is inefficient and highly costive, needs plenty ruling experience came from a series of ruling test to optimize and design it. In order to reduce the choosing range of experiential design parameters on chisel-edge grating ruling tool, to improve efficiency, and to reduce costs, this paper summarize the experimental results of several gratings ruling process for the experiential design on parameters of chisel-edge ruling tool. Provide the specific parameters choosing range as follows: that the blaze angle and directional angle difference in less than 3°, the bottom angle and apex angle difference in less than 5°. Apex angle larger than the groove bottom angle in conventional grating, while apex angle smaller than the bottom angle in echelle grating, and the directional angle smaller than blaze angle in both condition.
