Processing center G99 how to use, it is best to use examples, but also what the R value of what it means.
Fast positioning and feed down the drill bit!
Point (R1) drill down drill all the holes in turn. After drilling the first hole with G99, the spindle is quickly raised to point R and moved to the next point after the coordinates of the feed under the drill .R point that is the machine in the Z direction
This is a typical drilling procedure. After drilling the first hole (reaching Z-2) with G98, the spindle is quickly raised to the initial point (ie, Z10.) And then moved to the next point of the coordinates,
