Things like cutting with a mill and how to figure distance.
If I have a tool that has .5 inch diameter, and I need to come 12 inches off an edge. I zero my machine to that edge and then come over 11.75 inches to start the cut. The reason is half the tool diameter. Then I only cut 11.75 inches back on my DRO. Again, half the tool diameter needs to be accounted for because the DRO is measuring the center line of the machine and not taking into account the diameter of the tool..
Input is welcome on this.
If it's already here and I missed it, let me know.
