Turn milling is defined as the milling of a surface in which the workpiece rotates around a center. Eccentric shapes that are significantly different from conventional milling or lathe machining shapes can generally be turned by milling, which has high metal removal rates and excellent chip control. During rotation, the milling cutter can be fed radially to machine cylindrical surfaces
The milling cutter can be moved in both directions simultaneously, and eccentric surfaces can be machined. For example, a cam on a shaft moves along more than two axes
Needs a tool with ramping force that can move the cutter in both directions at the same time Needs to machine a taper, needs 5 axes
Turning and milling of complex contours (such as turbine blades) requires 5 (or 4) axis linkage, the workpiece is moved in 2 or 3 axes, and the tool is moved in 1 or 2 axes
What does turning and milling mean in CNC machining?
Parts such as turbine blades can be machined by rotating the part while feeding the milling cutter in more than 2 axes
The choice of turning and milling process Face turning milling - the main method of 4/5-axis cylindrical machining.
