The swiss type cnc lathe machine needs to complete the programming of various processing methods such as CNC turning, multi-axis milling, 3+2 positioning processing and drilling, which is very difficult. UGNX and CATIA systems have turning and milling complex CNC machining programming function modules.
When rough machining the revolving surface, inclined wall and contour cavity, solid, surface or curve can be used to define the area to be processed, and most of the blank material can be removed. It is suitable for the rough machining of all the outer shapes and inner cavities of the revolving parts. During rough machining, the machining strategy of following the part is adopted, and the machining toolpath is formed by offsetting the same number of steps along the geometric boundary of the part. When an intersection is encountered, one of the toolpaths is trimmed.
Under this processing strategy, the margin around the island area can be effectively removed. This processing strategy is especially suitable for cave-shaped processing with islands. Due to the uneven surface of the complex surface, the slope changes greatly. When 3-axis CNC machining, the continuous change of the cutting depth and cutting width will cause unstable tool load, aggravate tool wear, and reduce machining quality.
In areas where the surface is relatively convex and concave, it is easy to interfere with the tool and the workpiece, causing serious consequences. The positioning 3+2 processing method can overcome the shortcomings of 3-axis CNC machining of complex curved surfaces. If you want to learn CNC machining programming technology, I can help you in group 565120797. Turning and milling compound positioning 3+2 machining refers to turning the B and C axis to a certain angle and locking it for processing. When the processing of an area is completed, follow Adjust the angle of the B and C axis in the normal vector direction of the other processing area to continue processing.
The essence of the swiss type cnc lathe machine(sm325) is to change the five-axis simultaneous machining into a fixed angle machining in a certain direction, and the direction of the tool axis no longer changes during the machining process. Because it can realize processing in one positioning, 3+2 positioning processing has obvious advantages in efficiency and quality compared with 3-axis CNC machining. Turn-mill multi-axis milling finishing solutions. Use the multi-axis linkage machining method to finish machining multiple complex fragment surfaces of the cylindrical part of the complex rotating part, and select the machining geometry, drive mode and related parameters.
In the actual processing, the characteristics of the machine tool should be fully utilized to effectively control the change of the tool swing angle to make a good match between the displacement and the swing angle to prevent overcutting. In order to reduce the sharpness of the swing angle of the tool at the corner of the part, when processing the corner of the part, the transition tool position should be appropriately increased. This is also conducive to the smooth operation of the machine tool, avoiding overcutting, and improving the surface quality of the part.
