5軸加工と3軸加工の比較
Milling can obtain a good curved approximate surface. When using a ball-end tool for three-axis milling, the linear feed motion in the x, y, and z directions can ensure that the tool cuts to any coordinate point on the workpiece, but the direction of the tool axis cannot be changed. The actual cutting speed of the point on the tool axis is zero, and the chip space in the center of the tool is also very small. If these points are involved in cutting, the unfavorable cutting conditions will cause the quality of the machined surface to decrease, the blade wear will increase, and the machining time will be prolonged. So that high-grade tool materials are not fully utilized.
