CNC Milling is the most common form of CNC machining

The most popular or common form of Computer Numerical Control (CNC) function is CNC Milling. You can perform drilling and often turning functions on a CNC mill. The CNC Mills are classified by the number of axes they have.

Axes are labeled z for vertical movement and as x and y for horizontal movement. A standard light-duty manual mill is typically assumed to have four axes:

• Table x
• Table y
• Table z
• Milling Head z

A five axis milling machine has an extra axis, which is a horizontal pivot for the milling head, that allows extra flexibility for machining with the mill end at varying angles with respect to the table position.

A machine that has 6 axes would have yet another horizontal pivot for the mill head, which would be in a position that is perpendicular to the fifth axis.

G-Codes are the standard programming language codes for CNC milling machines. These G-Codes begin with the letter G and each number suffix has a specific meaning for machine movement.

No trackbacks.

In the 4-axis CNC, the first 3-axis are X, Y, Z. What is the 4th axis name ?

Can I use 4-axis driver for 3-axis application?

Thanks
