| Since the existing researches on Miter pipe were insufficient. its mathematical model was established and an
optimization formula on cutting speed was presented. Several common types of Miter pipe intersecting line and actual
cutting angle were deduced by utilizing the analytic geometry; analysis of the influence of the actual cutting angle on the
intersecting line and considering the cutting speed, an optimization formula on cutting speed based on the actual cutting
angle was presented. The optimization formula could effectively avoid defects when the pipe did not cut through the
corners. edges melt and groove deformed. The established mathematical model and the derivation of the cutting speed
optimization formula provide certain reference to the process of Miter pipe cutting. |
