Study on Symmetrical Machining Technology of a Ship Model Surface

Abstract:

Because a ship model surface (SMS) is a large symmetrical freeform surface (LSFS), the machining efficiency and precision of current handcraft method is very low. According to the shape characteristics of SMS, this paper adopted symmetrical machining (SM) technology to manufacture SMS, solved the collision of cutters or headstocks in SM process, proposed the machining solutions for symmetrical machining residuals (SMR), divided the manufacturing process to SM stage and SMR stage, and planed the tool path respectively. The real machining results of a twin-skeg SMS, which was machined by a 4-axis SM machine tool, conforms that the SM can reduce the SMS machining time from 60 workdays needed for handcraft method to 7 hours, and the machining precision and surface fairness are also improved obviously.
