Chapter 7:

2D Milling Toolpaths

Upon successful completion of this lesson, you will be able to:



CNC milling toolpaths are broadly classified as either 2D, 3D, 4-axis, and 5-axis, depending on the number of axes involved and how they move. The term, 2D, is a bit of a misnomer because all modern CNC machines control at least three axis and all three axes move at one time or another for every 2D machining operation. A more accurate term, 2-½D, is commonly used in CNC manufacturing.
