Abstract:

A new algorithm is presented for position regulating of aerofoil bracket on an automatic drilling and riveting machine. The algorithm, firstly figures out the normal vector to the drillrivet machining area on aerofoil surface by three points on the area, and then calculates the differences between this normal vector and the vector of the drilling and riveting axis of the machine. If there are differences, the algorithm further determines which axis of the aerofoil bracket should be adjusted and how much they should be adjusted.
