摘要:The purpose of this article is to become familiar with design of numerical control (NC) part programming of the computer aided manufacturing (CAM) process. This part consists in design of the CAM programs (postprocessors). The postprocessors are programs that convert a drawing, created by AutoCAD2000 by example, into G-code instructions which are used by G-code interpreter programs that in turn run the machine’s controller. Conversion of the drawing to a g-code file is an important step. The conversion must be accurate in order to enable the CNC machine part production with minimum human intervention
