Dro for mill

Yes, the Y axis will be fitted to front of table

Yes, the Y axis will be fitted to front of table

The table (left - right movement when stood in front of the machine) is normally the X axis - the Y axis is the underslide "in - out" movement.

Have a look at my DRO set up on my WM 16 mill, may give you some pointers, not the upmarket DRO that you have but it does the same job, & hasn't let me down ...yet!

Duh of course - my bad!

The way i explian it to newcomers ( on a mill ) is the x axis is across , it looks like a cross ( X) and travels across from left to right and vice versa when standin in front of the mill.

The y axis travel is toward You and away from You so think of the word You which starts with Y so it is the y axis .

Confusing isn't it.

When drawing a 2D graph youngsters are taught the mnemonic 'Y to the Sky', meaning Y is the axis running from top to bottom of the paper. Works on a vertical computer screen too; the Y axis runs from ceiling to floor. So far so good, but this isn't how dimensions run in 3D on Planet Earth!

On machine tools, as is right and proper, x is right-left, y is forward back, and z is up-down.

String theory suggests we live in an 10, 11 or 12 dimensional world. Just as well only 3 spatial dimensions matter to us - the thought of buying and fitting 11 DRO scales is just too painful!

Hello Dave,

I would not worry about the effects of String Theory. In 40 odd years of development, it has not predicted a single thing that can be verified experimentally. The inference that any sane person would make, is that the theory is wrong.

However it doesn't cost much to be a physicist who is involved in this folly, hence I suspect its popularity is largely down to needing only a small research grant! The King has no clothes comes to mind.
