【Abstract】 This paper states the method of measuring spiral angle ofthe graduated circle with such universal measuring tools ascombination set, sine protractor, gauge block, level--typedial indicator and so on. By means of analysing the measureddata with the method of minimum squares regression, therelative error of the computer calculating results of the spiralangle is only about zero point four--thousandths. The methodis applicable to measuring and inspecting helical gears.更多还原
