The rough wheels are hot rolled steel, whose dimensions are scattered in a large range. The wheels are produced by order with middle or small batch. The cycle of supply is short． Given the situation mentioned above, NC programming is requested to be fast， efficient， and accurate． Manual programming can not satisfy the demands of production． With no doubt, modem programming technology is the first choice. In recent years, automatic programming technology of singlecurer NC lathes has been researched widely in the world. However, the technology of twincutter NC lathes has barely been researched． Twincutter NC turning programming system is helpful to improve programming efficiency and quality according to enterprise’s requirements． In this system，puteraided technology is utilized in creation of the models， process planning， calculation of curer location data(CLDATA
