Tool offsets

Hi All
I recently bought a mill and have been using it in conjunction with Fusion 360. It works really well but I can't figure out tool offsets. I've got the offsets panel/window up with all our tools in it but it doesn't seem to work. After the roughing cut we have to manualy adjust the g code program so we can take the finishing cut to the correct size.

Cheers

Do you have your g-code set up to use tool offsets (g41,g42)

Thanks for the answers.

In terms of the G codes yes we were using the cutter compensation. That was for the main roughing cut, my problem is for the finishing cut.

In terms of Fusion we have the program cutting fine on the roughing cut but then for the finish we have to adjust the tool diameter in the tool table rather than just offsetting it. The issue with this way of doing it is that we're constantly adjusting tool diameter rather than setting stock tool diameters, it just seems a strange way to do it.

A real world example.
Say you want a pocket 50mm in diameter. You set it up in fusion leaving the tolerance for the finishing cut, say .2mm. You then measure the pocket and realise that it's left .22 mm on the cut so you need to run your finishing cut with an offset of .22 so that pocket is an exact size. To do that normally you run exactly the same program but just set your tool offset to .22 to compensate this.
At present you have to change the tool diameter to complete this or manually change all settings
