Making an efficient CNC program requires not just familiarity with CAD/CAM but also knowledge of real-world machining. This know-how takes into account such things as: cutting tools, machine power, part material and so on. Here is an example to show how ZW3D manages real-world machining. Safe Ramping Protects Tools from Breakage and Wear Rough machining often requires an efficient and strong cutting tool as shown in Figure 1. Since the tool obviously can't center-cut we must have strategies for dealing with or eliminating the rest-material (shown here in Figure 2). Figure 1 , Figure 2 Unless we carefully control the lead-in ramp angle, we risk destroying tools as shown in Figure 3. Figure 3 ZW3D can help you to avoid this situation as all roughing operations provide a safe ramp option. Selecting Yes in the Safe Ramp option (as shown in figure 4) means that all small areas moves that may damage the tool will be removed. Looking at the follow pictures illustrates the differences between Safe Ramp on and Safe Ramp off. Figure 4 Figure 5 About ZW3D ZW3D, the All-in-one CAD/CAM, was included into ZWSOFT's product portfolio in 2010. As the successor of VX CAD/CAM, ZW3D provides ease-of-use, performance, and all-in-one capability. The brand new software can extend enterprise-level mechanical design and engineering capabilities to the desktop at a fraction of the cost of other comparable systems.
