Development of Automatic Programming System for NC Laser Cutting of Chinese Characters

摘要

This paper presents an automatic programming system developed for NC laser cutting of Chinese characters which combines AutoCAD with NC under Windows environment, and generates numerical controlled programs by extracting outline (stroke) figures of Chinese Characters from outline character base, optimizing cutting routes, transferring them to AutoCAD for editing operations, such as rotation transfer, enlarging an mirroring, the system can transfer to a laser cutting machine through RS-232 series interface to accomplish laser cutting of large Chinese characters.
