When exploring x y z axis, it's essential to consider various aspects and implications. What do they stand for? When performing precision shaft alignment on horizontal rotating machinery, the Z axis refers to the rotational axis or rotational centerlines. The Y axis refers to vertical position (perpendicular to the base) and the X axis refers to the horizontal position (parallel to the base).
As seen in Figure 6a below. Why are X, Y and Z axes represented by Red, Green, and Blue?. Moreover, it is pretty standard that 3d axis, XYZ, is represented as red green blue, respectively. Why is this and who first proposed the colors in that configuration?
Does the Z Axis Affect Shaft Alignment? In short, no it does not. There are aspects of the z axis that could affect the running of a machine, but rotational shaft alignment is not of them. The X and Y axes are references to horizontal and vertical planes respectively.
Mill DRO - having extra scale (s) for Z axis. Furthermore, i am trying to decide if I want to spend extra for a scale on the knee and possible a scale on the quill (my understanding is that these two scales input the Z-axis display). Any of you splurged for a z-axis scale? Any of you regret not adding a 3rd or 4th scale to your mill when you bought a DRO? Moreover, x, Y & Z...Is it only me????
- The Home Shop Machinist & Machinist's .... X and Y axes are displaced 90 degrees from one another. It's important to note that, when standing in front of a mill, the convention seems to be that the X axis is table travel left and right, and the Y axis is movement in and out, with respect to the column. With the lathe, is the X the cross travel, and the Y up and down?
In this context, why is this, if this is the case. Furthermore, this is a standard Mill X/Y/Z Axis plan, on a lathe Z+ is into the spindle axis. Last edited by Peter N; 02-09-2013, 12:52 PM. Machine Axis & DRO Letter Designation - The Home Shop Machinist ....
Furthermore, yes, there are standards. Z axis is in line with the spindle, X and Y are transverse to the spindle axis. There are auxiliary U V W linear and A B C rotary axes and more. However, it can get a little slippery.
A milling machine is pretty straightforward where you have a transverse movement identified as X, a smaller fore and aft movement as Y and the up and down knee movement as Z. Lathe / Mill DRO axis + , - directions - The Home Shop Machinist ....
