Analysis of the application of five-axis machining center (equipment) for automotive interior parts

At present, the CAD system is mainly used to design auto parts, and the design of the parts is completed through reverse engineering and various tests. CAM software is used to process the complex surface of the mold. However, how to ensure the accuracy of design and processing depends on After CNC machining, the author analyzes the relationship between the application of five-axis machining center in mold processing and the quality of automobile molds.

Machining of Deep Cavity Moulds

In the process of automobile mold manufacturing, if a three-axis machining center is used to process deep cavity molds, the tool holder and tool must be lengthened in order to achieve this. To create better process conditions for machining, the additional rotation and swing of the workpiece or spindle head can appropriately shorten the length of the tool, thereby preventing the occurrence of collision between the tool, the tool holder and the cavity wall, and reducing the tool during machining. The vibration and damage of the tool are prolonged, the surface quality of the mold and the processing efficiency are also greatly improved.

Machining of mold side walls

For the processing of the sidewall of the mold, the tool length of the three-axis machining center is larger than the depth of the sidewall, and the length of the tool is also determined by the depth of the sidewall. If the length of the tool is increased, its strength will be significantly reduced. The double diameter makes the knife phenomenon occur, and the quality of the workpiece will be difficult to guarantee. For example, if a five-axis machining center is used to process the side wall of the mold, the swing of the spindle or the workpiece can be used to make the tool and the side wall of the mold appear vertical. When milling the side wall of the mold, a plane milling cutter can be used, which can improve the quality of the workpiece and prolong the service life of the tool
