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.
