Abstract: A novel method is proposed to calculate the minimum
distance from tool to free-form surface, to solve tool interference
problem in 5-axis NC sculptured surface machining. Projecting points on
surface to axis of cutter, calculating the minimum distance from axis of
cutter to surface, the amount of interference can be determined
directly; a corrective method for interference cutter-location is
proposed. The problem of global interference is solved successfully, and
the method has high efficiency and precision.
Key words: Minimum distance Global interference Cutter location
correction 5-axis NC machining
