Re: [CAD_CAM_EDM_DRO] G code Examples

John, that's pretty much the same way we do at school. This allows any
negative Z move to be an actual machining of the part and any positive Z
move to be above the part. This makes it easy to see whnen you have tool
clearance for rapid moves above the part.

We usually locate the X & Y axis (using the edge finder) on the lower left
corner of the part...unless we're using a fixture that provides us with a
known surface to locate the XY axis. This of corse makes it pretty easy to
machine all parts identical.


As for incremental co-ordinates, there are some Gcodes (on the schools
machine)that use them irregardless of normally using absolute coordinates.
