Briefly describe the application of five-axis machining technology (3)


Different five-axis machines use different five-axis controllers. The optimum operating point for some controllers is that when the origin of the workpiece is exactly coincident with the intersection of the rotating axes, some controllers perform best when fed in the opposite direction.

Many five-axis controllers with logic control know exactly where the tool origin is relative to the workpiece, regardless of how many times it is rotated. This feature is often referred to as "Rotating Tool Origin (RTCP)." Many users have found that advanced RTCP functionality makes five-axis applications simpler.

Five-axis CAM software

After using five-axis machining, the problem of 3+2 axis machining may not be completely solved. The programming problem has become a problem of CAM system, and vibration control has become the most important consideration. The CAM system only finds vibration between the workpiece, the tool, and the taper shank is not enough. It must also automatically eliminate these vibrations, so the CAM programmer does not need to manually adjust the tilt angle of tens of millions or more of the data points. It is. In addition, the five-axis automatic programming of the CAM system results in an optimized tool application, which is the shortest tool length (Figure 4).

Figure 4 The smaller diameter tool is milling the remaining material in the corner of the workpiece, thanks to the five-axis automatic programming for optimal results, which is the shortest tool length.

Unlike five-axis functions of special workpieces such as turbine blades, wing faces and thrusters, moldmakers do not have to “vertically” cut all the faces shown in the CAD file, they simply rotate a sufficient tilt angle to automatically eliminate The vibration between the tool, the taper shank and the workpiece can be used. Figure 5 shows that the combination of automatic toolholder vibration cancellation and more forms of cutting mode results in greater efficiency and flexibility in five-axis die machining.

Figure 5 is not only a simple taper shank vibration check, automatic tool shank vibration elimination is very necessary for the processing of deep cavity parts, especially efficient machining, automatic tool holder vibration elimination and more forms of cutting methods to make five-axis mold processing More efficient and flexible
