Abstract: Whether the tool radius can be reasonably compensated is the key to improve machining quality and efficiency. Based on the deep analysis to the error resulted from corner radius and the principle of tool compensation, the measures of tool compensation were proposed. It is proved that the correct compensation method of tool radius can efficiently improve the machining quality and efficiency by machining many parts.
Key words: tool radius compensation; computerized numerical control (CNC); linear interpolation
