In the CNC machining of the impeller blades, the machining of large impeller blades is the most difficult. Mastering the measures to solve the processing difficulties of large blades has a very positive effect not only on the large blade its....
Turbine impellers with complex shapes need to be machined with a 5-axis milling machine to be able to machine every corner of its geometry. In a modern design system, the geometry that needs to be processed is designed by the CAD system, and....
The use of short cutting tools is the main feature of five-axis machining. Short tools will significantly reduce tool deviation, thereby obtaining a good surface quality, avoiding rework, reducing the amount of welding rod used, and shorteni....
Milling can obtain a good curved approximate surface. When using a ball-end tool for three-axis milling, the linear feed motion in the x, y, and z directions can ensure that the tool cuts to any coordinate point on the workpiece, but the dir....
The five-axis machine tool with trunnion and planetary structure usually adds a two-axis rotary table on the basis of the standard three-axis machine tool. The advantage of this structure is that the parts are fixed on the centerline of rota....
Because the tool path is more complicated during five-axis high-speed milling, and the tool axis vector changes frequently during the machining process. Especially in high-speed cutting, the tool movement speed is very fast, so it is very ne....
With the increase of complex surface design of parts in modern industry, 5-axis machining will account for an increasing proportion of CNC machining. As 5-axis CNC machining adds two degrees of freedom of rotation, it increases the difficult....
Before the 5-axis milling tool path design, the system accuracy of the CAD 3D model should be set as high as possible. Especially when model conversion between different CAD systems, CATIA (*.model) format and Parasolid (*.x_t) format are pr....
Four kinds of standard threads can be turned on the CNC lathe: metric, inch, modular thread and diameter controlled thread. No matter what kind of thread is turning, a strict movement relationship must be maintained between the lathe spindle....
In the fine machining of thin parts, the difference from rough machining is that the influence of clamping force, cutting tool and process parameters on the internal stress of the part must be fully considered in the finishing process. As we....
