Why would we want to offset the coordinate systems to a work location? Think of work offsets as being like bookmarks. Why Offset Coordinates to a Work Location?
After the prior steps in the pipeline, our coordinates have been converted to the proper units (Imperial or Metric), converted to absolute coordinates (via G90/G91 status) and now we’re ready to offset those coordinate systems to the actual work location. This chapter on g-code programming is all about G52, G54, G92 and related work and fixture offset commands. Recall the Coordinate Transformation Pipeline that is used to convert coordinates in g-code to the active coordinate system the cnc machine uses for motion: CNCCookbook’s G-Code Tutorial Introduction
