In the realm of CAM processing, it's common to encounter workpieces with surfaces that are steep in some areas and flat in others. This irregularity often makes it impossible to complete the machining in a single process. However, in many cases, achieving a high-quality surface finish requires all faces to be processed in one go. The challenge is finding a method that combines both approaches efficiently. Fortunately, 3D CAD/CAM software now offers an advanced feature known as angle-restricted finishing, which helps engineers overcome these challenges seamlessly.
Engineers familiar with CAM machining know that using a contour tool on a flat area can lead to incomplete machining, as seen in the red region of the left image. This happens because the tool path remains uniform along the Z-axis. On the other hand, switching to parallel milling might cause uneven material removal in certain corners, as shown in the right image.
The angle-restricted finishing function in 3D software like Zhongwang 3D addresses these issues effectively. Let’s explore how Zhongwang 3D achieves this:
1. Start by clicking the "Process Operation" command from the menu bar (as shown in Figure 1), then insert the restriction contour and part into the feature (refer to Figure 2).
2. Select the appropriate tool.
3. Choose the machining area based on the actual geometry of the part.
4. Set the required parameters to optimize the toolpath for both steep and flat regions.
Once these steps are completed, the software calculates a precise toolpath that ensures full coverage of the entire surface, eliminating gaps and inconsistencies. This not only improves the quality of the final product but also enhances overall efficiency in the CAM workflow.
Zhongwang 3D also includes a user-friendly learning system, making it ideal for beginners and experienced users alike. With its intuitive interface and step-by-step tutorials, users can quickly become proficient in 3D CAD/CAM technology. Additionally, the latest version, Zhongwang 3D 2013, introduces a direct output feature to 3D printers, enabling faster prototyping and quality inspection—greatly reducing production costs for businesses.
As a preferred 3D CAD/CAM software recommended by the State Ministry for military enterprises, Zhongwang 3D provides cost-effective, comprehensive solutions for modeling, mold design, assembly, reverse engineering, sheet metal, and multi-axis machining. It is fully compatible with other 3D CAD software and comes with a rich library of parts, making it easy to learn and use.
