If this is tool wear then measure the tool with a micrometer and create a new tool with your measured diameter. Now regenerate the gcode using the newly created tool it should address your issue

All this was addressed in early CNC evolution with the machines capable of "cutter compensation".
Program it once, .... then adjust the toolpath by a value held into the offset field... at the machine

The trick is to select a programming method and stick to it.
(offset the path in CAM [WEAR, where zero offset value=programed tool diameter ] or offset in the control [CONTROL, where actual tool radius/diameter=offset value])

Safest is using WEAR, where all tools start with a zero offset, and they may need only minor adjustment IF/WHEN necessary.
