| Abstract: | To meet the need of high accuracy in NC machining, several errors and its cause have been analyzed from actual geometric angle of tool because tool tip of NC programming differs from cutting point of tool. Secondly, basic methods of decreasing the errors and trick of using instructions, such as G41 ,G42,G40, have been stated, which are efficient to improve NC programming and guarantee NC machining accuracy. It is capable of eliminating the phenomena of cutting more or less while turning fight plane, cone surface and circle arc through radius compensation. |
