Abstract: It puts forward a new conception of “forward and reverse adaptive reconstruction” . When the time grating sensor reconstructing the “extreme index” of the instrument, it reverse-retrofits the application objects of the instrument that include equipment and technology. The equipment can cooperate with the instrument to complete the “special detection” under the complex environment on site, and the technology can cooperate with the instrument to realize the “Super-normal guidance” of the processing process. The “instrument unit” and its design idea of embedding with the new type of worm gear pair mother machine, which can achieve the integrated process of processing and measurement, is introduced. The integrated process can not only discover the error law and self-check in the complex environment, but also guide the innovative process of error-induced remodeling and self-precision offset to realize extremely high precision. Target achievement: The instrument unit has been embedded in the product, implement the integrated process of processing and measurement, and a new type of worm gear pair mother machine which the product is a complete set of worm gear pairs, not just worm gears.

Key words: forward and reverse adaptation reconstruction, the instrument unit, special detection, integration of processing and measurement, complete set of worm gear pair
