TOOL PATH GENERATION AND TOOL SELECTION FOR 2D CNC ENGRAVING

Andrei Şteopan, Ioan Blebea

Abstract


In order to improve engraving efficiency, proper tools must be used along with adequate machining parameters. Tool path generation is the key ingredient in achieving a fast and reliable design by improving the machining process in both speed and quality. Taking in consideration the fact that usually there is no Z-level machining, thus eliminating the roughing and finishing stages, the machining time is mainly set by the complexity of the 2D shape and the material of the workpiece. The tools used are small angled cutters or end mills up to 3mm in diameter. This paper proposes a series of guidelines that will optimize the CNC engraving process.

Key words: 2D CNC engraving, workpiece
