G28 command returns the current tool to the CNC machine zero position via an intermediate point.

G28 command moves the current tool at a fast traverse rate (G00).

G28 is not a modal code.

The return to the CNC machine zero position is intended primarily for the possibility of checking the size and quality of the workpiece in some part of the CNC program.

G28 X... Y... Z... Z... A... B... C...

 
 X X coordinate of the intermediate point.
  Y Y coordinate of the intermediate point.
  Z Z coordinate of the intermediate point.
  R A coordinate of the intermediate point.
  P B coordinate of the intermediate point.
  F C coordinate of the intermediate point.

 

Example of using G28 in an CNC program.
