“…The basic design concept of mechanical fabricated diffraction grating is relative motion between grating blank and diamond cutting tool rest (DCTR) [5], mainly divided into three types: Rowland, Strong and Stowe Locke. Here, we focus on the type of Rowland, which means groove motion of the positioning stage and reciprocating motion of the DCT.…”

A high quality diffraction grating not only depends on the location accuracy of the positioning stage fixing the grating blank, but also the groove straightness error of the scratch system. As a key of diffraction grating fabrication technology at the nanometer scale, more attention should be paid to the dynamic characteristic of the scratch system. In this paper, both theoretical analysis and model simulation are carried out in order to study the vibration performance of the vibration source (slider crank mechanism) and knife-bridge. Moreover, the multi-body dynamics analysis of the knife-bridge is also calculated.
