有些作者提倡用线锯来做邻面切开以重组工作代型,在邻面切开技术中,即使锯片紧密靠近边缘,也会损坏代型的边缘。为了防止边缘破坏,另外一些作者提倡从模型的下面向上切开,这种技术需要特殊的设备,并且在另一方面,控制线锯切割方向是困难的。本文描述 Some authors advocate the use of jigsaws for face-cutting in order to reorganize the working sub-type. In the face-cutting technique, even if the blade is in close proximity to the edge, the edge of the sub-type may be damaged. In order to prevent edge damage, other authors advocate cutting up from below the model, which requires special equipment and, on the other hand, controlling the direction of wire saw cutting is difficult.
