The principle of turning curved surface is that a cutter moves along a rotating object, and the moving track of the cutter point moves circularly with a certain point as the center of a circle, so that the track formed by the cutter point on the object is a curved surface. When turning, the center lines of the workpieces are on the same plane. The processing method is to remove the small slide carriage of the common lathe and install a special tool capable of rotating to turn the inner arc surface. The curved surface processing method is approximately as follows: 1) The turning method of the forming knife is called a forming method, and the method is suitable for turning larger inner and outer circular arc grooves or forming surfaces with more numbers; 2) The profiling method is used for turning the formed surface, has the advantages of low labor intensity, high production efficiency and good quality, and is a relatively advanced turning method. The profiling method is particularly suitable for mass production with large quantity and high quality requirement. 3) The principle of turning the inner arc and the outer arc by using the special tool for turning the forming surface is as follows: the movement track of the tool nose of the turning tool is an arc, and the radius of the arc is equal to that of the arc of the forming surface.
When a common lathe turns a concave arc on a cylinder, the size requirement of the concave arc is controlled by manually controlling the movement of a middle and small carriage of the lathe (as in the prior published patent, CN 202621927U), and the method has the defects that an operator has higher turning skill, is inconvenient to operate, has low working efficiency, has poor machining precision and the like.
