CNC machining is also called computer gong machining or CNC lathe machining, which mainly processes aluminum parts and aluminum shells. Because in recent years, mobile phones, computers, mobile power supplies, and auto parts have prevailed. The requirements for improving the precision of CNC turning milling machining parts have changed from the other side to the process of CNC turning milling machining parts. Precision production of CNC turning milling machining parts Below, let me introduce the advantages of CNC turning milling machining parts.
Here is the content list:
l The formation of CNC turning milling machining parts.
l How to program CNC turning milling machining parts?
l Summary of CNC turning milling machining parts.
CNC turning milling machining parts are controlled by the automatic control system to install the data and program flow instructions to control the start and stop, speed adjustment, and speed adjustment of the rolling bearing of the CNC lathe. It is possible to select the CNC tool and change the amount of the tool and its moving trajectory according to the CNC tool. The various matching positions required in the processing will finally obtain the required CNC turning milling machining parts.
When rough machining the surface of revolution, inclined wall, and contour cavity of CNC turning milling machining parts, solids, surfaces, or curves can be used to define the machining area of CNC turning milling machining parts, and most of the blank materials are removed, which is suitable for rotating parts. Rough machining of all external shapes and internal cavities. During rough machining, the machining strategy of following CNC turning milling machining parts is adopted. The machining toolpath is formed by offsetting the same number of steps along the geometric boundary of the CNC turning milling machining parts. When encountering an intersection, one of the toolpaths Trims off.
Under this processing strategy, the margin around the island area can be effectively removed. This CNC turning-milling machining strategy is particularly suitable for hole-shaped machining with islands. Due to the uneven surface of the complex surface, the slope changes greatly. When 3-axis CNC machining, the continuous change of cutting depth and cutting width will cause unstable tool load, aggravate tool wear, and reduce machining quality.
In the places where the surface of CNC turning milling machining parts is more convex and concave, it is easy to interfere with the tool and the CNC turning milling machining parts, which will cause serious consequences. The positioning 3+2 processing method can overcome the shortcomings of the 3-axis CNC machining of complex curved surfaces. Turning and milling composite positioning 3+2 machining refers to turning the B and C axes to a certain angle and locking them for processing. When the processing of one area is completed, the B and C axes are adjusted according to the normal vector direction of the other processing area. Continue processing at the angle of.
Its essence is to change the five-axis linkage machining into a fixed angle machining in a certain direction, and the direction of the tool axis no longer changes during the machining of CNC turning milling machining parts. Because it can realize processing at one time, 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, so that the displacement and swing angle of CNC turning milling machining parts can be well matched to prevent overcutting. To reduce the sharpness of the swing angle of the tool at the corner of the part, when CNC turning and milling the corner of the part, the transition tool position should be increased appropriately, which is also conducive to the smooth operation of the machine tool, avoiding overcutting, and improving CNC turning and milling. The quality of the machined surface of the part.
