ZW3D's Undercut Feature Expands Your Machining Capabilities
August 21, 2012
Sometimes, parts have areas that the usual 3-axis milling programming strategies cannot handle, such as the undercut shown in figure 1.
Figure1. One type of undercut position
If you were to use EDM for the undercut, it would increase your costs and machining time. If instead you were to use 5-axis milling, then this too would increase the cost – never mind that not all machining companies are equipped with 5-axis machine tools.
Figure 2 shows another undercut example, and it too would be difficult to do with a general 5-axis machining method.
Figure2. Another type of undercut position
The solution is found in the undercut feature provided with ZW3D. With this function, ZW3D is able to machine these position just using 3-axis machine tools. You find the function at the Z level operation and Lace operation. See figure 3.
Figure3. Under Cut feature in ZW3D CAM
You can choose a formed milling cutter, and then choose the undercut option. ZW3D automatically detects the undercut position, and so generates the appropriate toolpath. The result is shown in figures 4 and 5.
