In the joint of LG PEX-A Pipe ,male xocket is pressed to a convex on the inserting part and the fastening ring will contract to fasten up the heating pipe by the fastening of outer nut,and there is also a convex on the ring to offer close coupling by mechanical re-press effect to prevent water from leaking in case of heat expansion.

在LG地热管中的连接部位不仅阀门管套插入部分的凸起部位被机械作用压密，而且随着外部螺母被拧紧，使紧固环收缩，从而带紧热炕暖气管，另外由于存在凸起部位，可通过机械作用进行再次压密，因此可防止由于热膨胀而引起漏水。

In this study, a commercial CAD/CAM Software is used to plan and generate the multi-axis tool path, and a table rotating/tilting type five-axis machining center is used to perform the experimental machining operation. The material of the die studied is NAK 80 die tool steel, and the geometries are modeled as concave and convex spherical surfaces. Milling parameters considered are spindle speed, feed rate, and different types of cutting tool path. The experimental results show that the surface roughness for concave spherical surface is about 0.247 μm and roundness is about 0.0283 mm and the surface roughness for convex spherical surface is about 0.250 μm and spherical roundness is about 0.0551 mm under the cutting conditions mentioned in this study.

It respectively constructs quasi projection-separation facet sets of two convex polytopes while their orthogonal projection on the centerline overlap mutually. Afterward it judges the separation of two convex polytopes by confirming non-overlap in orthographic projection on the centerline or by finding out a projection-separation facet from two quasi projection-separation facet sets, otherwise a collision is judged.

该算法通过判断2个凸多面体在中心线上的正投影不相交，或者分别构造它们的准投影分离面集合，并从这2个集合中找到一个投影分离面，来判断2个凸多面体分离；否则，判断为相交。
