Paper Abstract

By analyzing the measuring principle of tool maker's microscope, the article presents a new method for thread measurement with a tool maker's microscope assisted by computer. Special real-time image sampler was developed. A new measuring system was established and relative software has been designed. For the hardware design, the technique of DMA transfer data was adopted and the real-time sampling of one field of image was realized. For the software design, both assembly language and high level language were used. Image sampling and edge detection were operated by assembly language rapidly and the thread parameters were calculated by high level language. Experiments show that the system can measure the thread parameters automatically and rapidly. The study of computer-aided measurement of thread accuracy with a tool maker's microscope is useful to realize the intelligent measurement of another shape accuracy with a tool maker's microscope.
