One of the effective method of improving diamond tool life on rulling large diffraction gratings is developing precise double-cone edged on line edge transfering tool. But traditional died weight or manual lapping technique couldn't meet the precision requirement of on line edge transfering tool. So preliminary studied rigid lapping of diamond grating ruling tool. Choosing traditional BC6063 shaping machine and made a series of alteration on it  achieved the automation of lapping process of diamond grating ruling tool. Through lapping grating ruling tool and AFM measurement find that the surface roughness of tool is 1.51nm  the radius of tool edge is 160nm  edge quality is good enough  this verified the feasibility of rigid lapping of diamond grating ruling tool and lay the foundation for developing precision lapping machine.

The remarkable improvement of sensing and processing hardware performance makes the non-contact  on-line  high accuracy and high speed measuring possible by means of linear CCD. The goal of this pager is to describe the key questions on designing the cone diameter detecting system by linear CCD. This paper first describes the detecting scheme. In particular  the factors affecting accuracy  such as resolution  voltage difference between neighbor pixels  detecting rate and so on  are analyzed  and the quantitative estimation equations are provided. CCD takes on the photoelectric translation and measuring component double functions  so the waveform of CCD output signal and the affecting factors merit deep discussion. On the basis of discussion  several principles that can be used to improve the boundary recognition accuracy are presented.
