Studying the Design and Verification of 5-axis NC program under the Manufacturing System

NC programming, based on part profiles, is the conventional theory involved in the NC codes creating tasks; this is not wrong but far from satisfying the needs of the 5-axis NC cutting jobs. Viewing from the manufacturing system level and taking the transmission lower tank cut job on the 5-axis MC (machine center) as an example, the author deeply investigated and summarized the technique principles and algorithms of all works involved from a manufacturing system preparation to the 5-axis NC program verification with the help of computer aided technologies. The program design for the 5-axis NC machining is achieved with the CAM methods, and the correctness of the NC codes is guaranteed with the Post-NC verifying. All these principles and algorithms are general and practical, and can be applied by the 5-axis MC users to promote their production quality, efficiency and cost targets.
