Vysotskli When appraising the economic efficiency of automatic inspection machines, it is necessary to know the number of articles scrapped because the automatic machine makes measurement errors, due to which some of the good products are scrapped and some of the faulty articles are passed. A large amount of work in rechecking articles scrapped by the automatic machine lowers its efficiency. A knowledge of the number of good articles among those rejected ~;[_[~----- .............. ....... ~- ~--~~/ by the automatic machine, as well as the number of faulty articles Study of the measuring devices of automatic inspection ma- chines equipped with electrical contact and pneumatic transducers O[-I~"T I I ..I I .(. showed that the distribution of random measurement errors follows 3 I0 20 30 ~0 % ~-~ the normal distribution law very closely. Fig. i The distribution law, which sometimes deviates from the nor- mal, and the expected percentage of actual scrap should be deter- mined experimentally, for the preliminary calculations, from the operation of the equipment under consideration. We shall quote some calculations of the rechecking required for an automatic machine which checks one parameter for two limits. Approximate data for multidimensional automatic machines
