Program 4
LE33013R0300800120007
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.
LE33013R0300800120008
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.
