Setting 52 changes the way G83 works when it returns to the R plane. Usu-
ally the R plane is set well above the cut to ensure that the peck motion allows
the chips to get out of the hole. This wastes time as the drill starts by drilling
“empty” space. If Setting 52 is set to the distance required to clear chips, the R
plane can be put much closer to the part being drilled. When the chip-clearing
move to R occurs, the Z axis distance above R is determined by this setting.
