G53

Machining center, LatheOne-shot, group 00

Machine coordinate system selection (positioning in machine coordinates)

⌨Format and notes

G53 G00 Z_ (machine coordinates for that block only)

In that block only, ignores work coordinates and tool offsets and moves in machine coordinates
Cannot be used during cutter compensation (NIST)
Used to bring the table forward after machining, raise Z to machine zero, etc. (Saitama University practical training example, Haas example)

Diagram: Machine zero and work zero (coordinate systems)

Only the G53 block positions in machine coordinates, measured from machine zero, without the work coordinate offset.

The meaning shown agrees in at least two sources (agreement confirmed). Explanations are written in our own words.
