A numerical control transformation (NCT) system for a conventional lathe machine is introduced in this paper. The NCT system is considered as the key equipment to the manufacture of the transmission shaft. According to the construction feature and technological requirements, both the hardware and software construction are analyzed, as well as the implementation method of the NCT system. By practical operation, the experiment test result is given at the end of the paper to support the usefulness and practicality of the NCT system.

Impact and vibration are two of the thorniest technical problems to hybrid machine tool. In this paper, the kinematics principle of the hybrid machine tool was proposed as well as the suppression algorithm, which was based on the velocity optimal control algorithm (VOCA.). And this algorithm was carried out after fine interpolation. It was proved by experiment on hybrid machine tool that the impact was reduced effectively by this way. Account for the velocity optimal control algorithm, the velocity performance of the machine was improved, especially when kinematics calculation error occurred.
