Abstract

A new method, in which suitable tool paths are generated in
order to manufacture pockets in CNC milling machines, was developed in this
study. For this purpose, a new algorithm was developed in
order to offset pocket profiles with or without the island. In addition, errors
that may arise as a result of offsetting were also eliminated. The tool path was
generated by using the offset components obtained through this offsetting
process. The acquired tool paths were tried after being sent to CNC milling
machine. The success of the developed method was proved without any hollow or residue.

Keywords
