A CNC machining center moves on three axes of travel. It uses a machine coordinate system
and a part coordinate system to identify positions on the axes. Learning about how a CNC
machining center moves and identifies positions will help you understand how the geometry of a
part is defined and how the part is machined.
By the end of this course, you will be able to
• Define movements on the Z-axis
• Define movements on the Y-axis
• Define movements on the X-axis
• Describe the machine coordinate system
• Define machine home
• Describe the part coordinate system
• Define part zero
• Describe how ordered triplets are used to define the geometry of a part
