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....
Turning and milling thin parts (aluminum, aluminum alloy, pure titanium, copper, magnesium alloy) are always prone to deformation during machining. Oval or waist shape with a small middle and large ends, which makes it difficult to ensure t....
The development of three-dimensional design software provides conditions for low-cost, short-period, and design of positioning fixtures. And it can simulate CNC machining parts for verification. Figure 1 shows a typical metal part with an an....
For CNC machining of aluminum parts with a large margin (large, thin-walled, aluminum cavity parts), in order to have better heat dissipation conditions during the machining process and avoid heat concentration, symmetric machining should be....
There are many reasons for the deformation of machined aluminum parts, which are related to the aluminum material, the shape of the part, and the CNC machinery and equipment. There are mainly the following aspects: blank internal stress, cutting force....
