SECTION 6 OFFSET FUNCTION
Program 5:
LE33013R0300800120010
In this looping path, the tool nose R moves inside the programmed rectangle, N3 - N31 - N32 - N33.
Therefore, axis behavior can be easily expected if only these respective sides are longer than twice
the tool nose R (four times on the X-axis).
Since this program still leaves an uncut portion, it can be further improved as indicated in program 6.
Program 6
In this program, point N3 is shifted in the -Z direction by an amount equivalent to the tool nose R to
eliminate the uncut part seen in Program 5. This program gives a fully satisfactory result.

Program 6:
LE33013R0300800120012
Programs 1 through 5 will provide some clues to complete the program for the intended cutting.
As an imaginary shape for tool path looping, select a rectangle or polygon but not a triangle.
Triangles are apt to lead to unexpected tool movements.
