SOME POSSIBILITIES FOR STERN-TUBE BUSHES INNER SURFACES MACHINING WITH DIMENSIONAL ADAPTIVE CONTROL

In the shipbuilding industry, one of the problems difficult to be solved is the stern tube bushes inner surface machining. The results of this process are often affected by errors - process errors, system errors and also errors caused by ship hull mechanical and/or thermal deformations. Sometimes, their level can cause serious troubles. These errors could be at least partially avoided by using a dimensional adaptive system to control the machining process. In this paper, a device imagined in this purpose is presented, designed as ensemble at conceptual level. Its practicability at industrial level, in the shipbuilding, but also in machining of the large holes from extreme dimensions parts, in general, will be further tested.
