Aiming at the problem of the relatively low accuracy and speed of NC machine's feed motion derived from the present pulse incremental interpolation algorithm and the digital sampling interpolation which is only suitable for the closed loop control system, a high-speed digital signal processor(DSP) has been raised for the realization of the rough interpolation of data sampling software; and a complex...
To achieve a high efficient machining for developable ruled feature surface such as conical surface, column and plane, twisted ruled surface, free curved surface an and so on, a new method of line contact rotatory machining based on direct surface machining is proposed. And in this new method, in order to solve the problem that automatic processing is discontinuous and unstable in real-time control...
Point contact machining has been widely applied in surface machining recently. However, the point contact area, the contact area between the cutter and the workpiece, is small and often leads to low efficient machining. Moreover, inequable curvature of the contact point in the contact area also results in different cutting speed at every bit of the cutting blade, these two defects together may result...
