Answer :
Two major differences between CNC milling and CNC lathe are the type of motion and the orientation of the workpiece.
In CNC milling, the cutting tool rotates while the workpiece remains stationary, allowing for various cutting operations on different surfaces. On the other hand, the CNC lathe rotates the workpiece while the cutting tool remains stationary, primarily used for cylindrical turning operations.
Type of Motion:
The primary difference between CNC milling and CNC lathe lies in the type of motion involved. In CNC milling, the cutting tool rotates and moves along multiple axes, allowing for complex cutting operations on different surfaces of the workpiece. The cutting tool can move vertically, horizontally, and even at angles, enabling operations such as drilling, slotting, and contouring. CNC milling is ideal for creating intricate shapes and features on a variety of materials.
In contrast, CNC lathe primarily involves rotational motion. The workpiece rotates about its axis while the cutting tool remains stationary. The cutting tool moves along the length of the workpiece, performing operations such as turning, facing, and threading. CNC lathe is commonly used for cylindrical components, creating symmetrical shapes, and achieving precise diameter and length measurements.
Workpiece Orientation:
Another significant difference between CNC milling and CNC lathe is the orientation of the workpiece during machining. In CNC milling, the workpiece remains stationary and is clamped to the table or fixture. The cutting tool moves across the workpiece in multiple directions, allowing for operations on different surfaces and angles. CNC milling can accommodate a wide range of workpiece sizes and shapes.
In CNC lathe, the workpiece is mounted on a spindle and rotates about its axis. The cutting tool is positioned parallel to the workpiece axis and moves along the length of the workpiece. This setup is suitable for machining cylindrical parts with rotational symmetry. CNC lathe is commonly used for tasks such as turning, facing, and creating threads on cylindrical workpieces like shafts, rods, and tubes.
In summary, CNC milling and CNC lathe differ in terms of the type of motion (rotational and multi-axis) and the orientation of the workpiece (stationary and rotational). CNC milling enables complex cutting operations on various surfaces, while CNC lathe is focused on cylindrical turning operations. Both processes have their unique advantages and are essential in modern manufacturing for different applications.
