Rotary XY Datum

[gerry]

The most popular approach seems to be to set center of the cylindar at:

X = Center line from chuck to tailstock i.e. The center line down the length of the rounded piece.
Y = Center point of stock from chuck to tailstock i.e. center from top to bottom of cylindar.
Z = Center point of tailstock.

Correct?

If I have that correct, is the Job Setup in Vectric at the bottom left point, or the center point. I'm betting on the center point, but I could be incorrect due to the wrapping of the flat surface.


Clarification please.

P.S. Sorry if I missed any terms, but I'm travelling with only my tablet, and it doesn't run Aspire..... I'm typing from memory.

You are correct that it would be the center point in the software if that is the XY datum you wish to use on the machine.

On the machine end, it is good practice to locate the rotary and chuck just outside of the Y-limit.  Prevents unwanted crashes into the chuck
