In order to overcome the disadvantages of interactive definition of the pockets and islands, this paper presented a simple and effective pocket milling region identification method.To identify pocket milling region,this method constructed tool path loop(TPL) relation matrix firstly, and then constructed the TPL-tree by the way of querying information in TPL relation matrix.After the TPL-tree was obtained,the purpose of complex pocket milling region automatic identification can be achieved by evaluating the level of the node, this method does not need user to participate directly, and thus reducing the user’s burden and avoiding the possibility of mistakes.Examples show that the method can effectively and automatically identify pocket milling region, so the programming efficiency can be improved by simplifying NC programming steps.
