• Arc in two quadrants
a. Case where the arc radius is greater than "2 x nose R":
LE33013R0300800100017
The tool position determined by the commands in the N2 block is the point where the tool
nose R comes into contact with line N1 - N2 at point N2. In the N3 sequence, the cutting
tool is positioned so that it comes into contact with both the extension of straight line N2 -
N3 and the extension of arc N3 - N4.
