Abstract
To allow automatic determination of the order of drilling in slot drilling. The positions of holes located along a line are described via a binary vector. The order of drilling is also described via a binary vector. The former binary vector is made to correspond to the latter binary vector through a conversion matrix, where every corresponding partial matrix is regular. The positions of the holes are determined from the drilling order, or the drilling order is determined from the positions of the holes by their correspondence.
