Lathe Software Conventions

Posted by  7xCNC  Nov 9, 2012

Z is the long axis of the lathe

Z0 is the end of the stock

-Z is then towards the chuck, and +Z towards the tailstock.

X is the cross slide

X0 is the centreline - the very point of the tool should be on the centreline at X0

+X depends on the machine, but in a converted manual lathe is usually towards the operator. And -X away from the operator.
