G51: Scaling the Coordinate System - G-Wizard Calculator ...

So you're off by 0.0007" and need the hole to be larger. - So, your g-code performs a little calculation. 0.0007" / 2.0000" is 0.00035. Now you know the correction factor that's needed. - When you make your finish pass, use G51 to scale the finish pass to 1.00035x the coordinates that are in the g-code program.
