13.00 Introduction

On this page


Once a 3D digital model is created, a toolpath must be made so the CNC machine has the information needed to cut out the project. THis requires making a “tool” with the measurements of the cutting device used on the CNC. Then the stock, material used for cutting, is defined as well as the location of all the cutting operations. Finally before cutting, clearances can be added to the cutting operation to allow parts to fit together.
