Technical Examples

The shapes of machine parts for which the possibility of interference exists are defined as rectangular parallelepipeds and it is judged whether or not there is interference between a first rectangular parallelepiped of a first machine part and a second rectangular parallelepiped of a second machine part. The method involves rotating the first rectangular parallelepiped and second rectangular parallelepiped so that each side of the first rectangular parallelepiped lies parallel to each axis of the reference coordinate system. Interference is thus judged based on whether any vertex of the second rectangular parallelepiped exists within the first rectangular parallelepiped. Likewise, interference is judged depending on whether any vertex of the first rectangular parallelepiped exists within the second rectangular parallelepiped. Further, interference between the respective sides of the first rectangular parallelepiped and second rectangular parallelepiped is judged through division into the planes X-Y, Y-Z, and Z-X. When it is judged that interference exists in all planes, it is judged that there will be interference between the first rectangular parallelepiped and second rectangular parallelepiped.
