Example program for the path above:
N0 G42 G00 X100 Z300
N1 G01
N2 X104
N3 G00 X200
N4 G01
It is advantageous to improve the program and eliminate a positioning sequence to a distant
point through commands in the N3 block.
If N2N3N4 were not a sharp angle, such a problem would not occur. To eliminate sharp angles
from the required contour, one possible solution is to interpose a short straight line N3 - N31.

N 2
In some cases, such a modification is not possible. In these cases, to cut a sharp angle without
positioning the cutting tool at a distant point, follow the steps detailed below.

N3 G00 X200.48
N4 X198.48
N5 X198
N6 G01 X200
N7
In this improved program, the cutting tool moves along the imaginary square N3N4N5N6. This
permits the operator to estimate the departure of the cutting tool from the programmed contour.
Note that one side of the imaginary square must be longer than twice the nose radius.
