Research On The Automatic Detection Method For Square

Squareness and straightness measurement is the important kind of Lengthmeasurement. Many measurement tool has its own working surface squareness andstraightness requirements, which is the most typical square. The square is a traditionalindustrial areas of common measuring tool, its precision range from mm level workwith the use of gauges to micron level gage.This article introduces the current square verticality method, points out itsadvantages and disadvantages. In order to put forward to the original KUNZ squaretester for transformation, to achieve the right angle ruler squareness and straightnessof the automation testing, and use the Microsoft VS2010design data processingsoftware, the method of least squares fitting curves are obtained finally the results.And will generate EXCEL files directly into the Shanghai Institute of measurementand testing technology focused on the promotion of LIMS system, to achieve thedetection program in LIMS system and seamless connection.Uncertainty in Measurement is the new results indicating means in the worldrecently. By this means, it can evaluate the results of measurement quantitativelyand scientifically. The uncertainty in measurement is one of the main elements todetermine the results of measurement. So the results of measurement are not entireand significant without uncertainty explanation.Based on the modified square tester indication error uncertainty verificationautomation scheme is correct.Finally, this article verified the project by the flatness measurement practicality. Itapproved this project is in favor of choosing the reasonable measuring plan, avoidingthe measuring errors by using the incorrect way, increasing the results reliability.The program of the flatness measurement can prevent the man-made errors in thedata processing, it can find out the results of measurement and uncertainty inmeasurement in the fieldwork rapidly.
