圆柱形壳体上开大直径相贯圆孔的数控切割原理

Principle of CNC Cutting a Large Intersecting Round Hole on a Cylindrical Shell

对在圆柱形壳体上开大直径孔的数控切割原理进行了分析 ,主要是针对大直径开孔所涉及到的重要的空间几何关系和运动关系的计算 ,并介绍了DKK

In this paper,the principle of CNC cutting a large intersecting round hole on a cylindrical shell is discussed.The discussion is mainly focused on the calculation of some important geometrical and motional interrelations between the hole to be shaped and the shell to be cut.The design and practical operation of Type DKK 1 CNC flame cutting machine for cutting a round hole of large diameter on a cylindrical shell is introduced.
