摘要
In this paper, the G-coding method in computerized numerical machining of a printed circuit board （PCB） is presented. PCB design data, which will be generated as the input data of standard G-code, is available to be obtained with ASCH or Excel format through the data exchange inte^ace of an EDA software Protel. With this open numerical control engraving system based on ＂PC ＋ motion controller＂, it is possible to realize rapid PCB plotting in a small quantity, which is characterized by low cost and high accuracy, signifwantly shortening the R＆D cycle of electronic products.
