What is End Milling in Precision Parts Processing
In the field of precision parts processing, end milling refers to milling with the end tooth edge of a milling cutter. When milling the plane, the tool tip distributed on the end face of the milling cutter is used to form the plane. The plane milled by the end face washing method also has a series of knife lines. The thickness of the knife lines (that is, the size of the surface roughness value) is also related to many factors such as the feed speed of the workpiece and the speed of the milling cutter.
In the process of precision parts processing, a plane is milled by end milling. The flatness mainly depends on the perpendicularity of the spindle axis and the feed direction of the milling machine. If the spindle is perpendicular to the feed direction, the path of the tool tip when rotating is a circle parallel to the feed direction, which cuts a plane. In fact, the tip of the milling cutter will mill a net pattern on the surface of the workpiece. If the spindle of the milling machine is not perpendicular to the feed direction, it is equivalent to cutting a concave surface on the workpiece surface with an inclined ring. At this time, the cutter tip will mill a unidirectional arc pattern on the workpiece surface.
