CNC machining technology involves a wide range of factors and is influenced by numerous elements. When analyzing the processing techniques for workpieces, it's essential to take into account the specific characteristics of CNC machine tools. This ensures efficient programming and maintains consistency between design, process, and measurement standards.
1. **Analyzing Dimensioning Methods in Part Drawings**
Dimensioning on the same reference or directly using coordinate-based labeling is known as the unified benchmarking method. This approach (as shown in Figure 1) is highly suitable for CNC machining because it simplifies programming and aligns with both the design and manufacturing standards. Designers often use localized dimensioning methods (as seen in Figure 2) for assembly and functional considerations, which can complicate process planning and NC programming. Switching to a unified standard helps reduce cumulative errors, especially given the high precision and repeat positioning accuracy of CNC machines.
2. **Analyzing Geometric Element Conditions Forming Part Contours**
The geometric conditions that define the shape of a part are crucial for NC programming. For manual programming, calculating the coordinates of each contour node is necessary. In automated programming, all geometric elements must be clearly defined. If the drawing lacks sufficient details, it becomes impossible to determine the nodal coordinates or the geometry, making programming unfeasible. Therefore, part drawings should fully express all the geometric elements that form the contour.
3. **Analyzing Workpiece Structure Feasibility**
1) The internal cavity and shape of the workpiece should be designed with uniform geometry and size. For example, the diameter and undercut width of a shaft shoulder should be consistent to minimize tool size and reduce the number of tool changes, improving programming efficiency and CNC machining performance.
2) The radius of the transition fillet between the slot and the edge plate should not be too small. As shown in Figure 3, if the radius R is less than 0.2 times the depth H of the contour, the machining quality may be compromised. However, when R is greater than 0.2H, the tool’s stiffness improves, ensuring better machining results.
3) The bottom radius of the workpiece groove should not be excessively large. As illustrated in Figure 4, a larger bottom fillet radius reduces the effective cutting area of the end mill, limiting its ability to machine flat surfaces. This can affect surface finish and machining efficiency.
4) Analyzing the Reliability of the Part Positioning Reference
CNC machining should ideally use a unified reference for positioning. Failing to do so can lead to positioning and shape errors. If the workpiece needs to be turned on a CNC machine, it's best to use a previously machined outer diameter or inner hole as the reference. If not possible, an auxiliary reference should be added, such as a process boss or a manufacturing hole, which can later be removed after processing.
