Program 4:
In this program, a tool looping similar to that performed in program 3 is executed with the numeral
values modified to avoid overcutting.
N1
G42
N2
N3
N31
G00
N32
N4
G01
This program almost yields the expected finish. However, there are still latent problems, such as:
•
overcutting is caused depending on the size of the tool nose R
•
the length of side N31 - N32 cannot be readily found.
These problems are solved by looping the tool path along a square as explained next.
Program 5
Program 5 solves the problems encountered with program 4.
