How does a CNC milling machine process heterosexual curved surfaces?

When processing planes, auto parts, impellers, propellers and various curved surface forming molds, the use of computer gong processing can ensure the accuracy requirements of special-shaped parts and curved surfaces, and greatly improve the processing efficiency. So how do you process special-shaped curved surfaces?

1. Establish a mathematical model

Before building a model, we should first consider the sequence and method of building each feature of the model. What to do first, what to do later, what method to use, and which modeling function to use. This must be considered when building a mathematical model. This relationship is handled appropriately.

2. Determine the processing coordinate system

The establishment of the solid model is based on the work coordinate system, and the generation of the source file of the machining tool position of the CNC machining center is based on the machining coordinate system. The position of the coordinate origin of the machining coordinate system should be convenient for the processor to quickly and accurately set the tool, and at the same time to facilitate the size calculation that needs to be carried out during the machining process.

3. Plan the tool location source file

According to the structural characteristics of different product profiles, we can choose three processing modules with their own characteristics, such as plane milling, cavity milling and fixed-axis contour milling, to plan the source files of processing tool positions for various types of surfaces.

In short, we should flexibly grasp the application characteristics of each module according to the difference of the processed surface and the contour surface, so that we can process our satisfactory products with high quality and high efficiency through the CNC machining center.
