You'll use your CNC milling coordinate system fundamentals everywhere, not just for one particular CNC machine. Even the latest CNC machines are the same at their core: they use an X, Y, and Z-axis to define the coordinate space inside the machine, and a tool (sometimes an endmill, sometimes an extruder, sometimes a laser beam) moves around that space.
In some vertical milling machines, you can adjust the spindle up and down. 3. Universal Milling Machine. Universal milling machines can adapt to perform a wide range of operations.

1. Move an axis in one direction farther than the maximum possible backlash. (Example .020, hopefully less than that is needed!) 2. Mount a dial indicator and zero it. 3. Move the axis again in the same direction for a specific distance (it doesn't matter how far). …
Tramming a Milling Machine: Tools, Indicators, & Tips. Tram is the squareness of your mill head to the table and Tramming is the act of adjusting the mill head to be square.

Milling Machines in the United States. When, more than half a century ago, the ingenuity of the Yankee gun maker devised a machine that could be substituted for hand labour in the manufacture of the irregularly-shaped parts entering into the mechanism of firearms, the first step toward the successful duplication of gun parts was accomplished.
The normal method for adjusting the machine's backlash involves adjusting the backlash parameter values. This can be done by a qualified technician or you can give it a try. Outlined below is a brief but complete explanation of how to check for backlash and how …

Stick-slip motion is one of the factors which makes fine adjustment of a slide difficult. For example, if the wheelhead of a grinding machine is to be adjusted to remove 0.01 mm from the diameter of a workpiece the slide must move 0.005 mm.
The best way to correct axes (at least with box way construction) is to adjust the machine's gibs to eliminate the backlash all together. When you must machine holes in precise X, Y locations (when finish boring, for example), backlash can cause positioning errors in hole locations if the motions required to machine the holes cause a reversal ...
This attachment is desirable on horizontal milling machines for substituting the horizontal spindle by a vertical spindle motion. The attachment is a right-angle gear box having bevel gear set in ratio of 1 : 1 and the axis of the vertical spindle could also be swivelled by 45°, thus allowing the machining of bevels and slanted surfaces.
