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.
Objectives
By the end of this course, you will be able to do the following:
- 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
