program control can take the bronze knife or also bronze knife action

 The command after immediately stop the bronze knife library operation, and did not finish the distance to delete this bronze knife library fine positioning is completed, that the bronze knife positioning of the library to find bronze knife or also bronze knife positioning is completed when the manipulator in the PLC program control can take the bronze knife or also bronze knife action. Bronze knife-bit to 40; switch to Siemens PLC. It the two Han Dynasties, especially the Eastern Han Dynasty, the smelting industry of the bronze sculpture at the Sichuan and Yunnan was highly developed.  300 control system; increase in the design of the manual control; programming, automatically selected bronze knife on the basis of the election bronze knife of computer memory using the Siemens 840D.
Features make the program more concise selection of bronze knife, and complete the empty bronze pocket search, which is the innovations in this area point where fast algorithm for-bronze knife; in the database, and gives the auto-programming-for-bronze knife; given the soft bronze knife library positioning control, hardware design, PLC programming control modular design, this producing a similar machine in the future will be very beneficial, it is easy to use it to other machine tools; bronze hilt specifications using the BT45, the largest bronze knife length is increased to 400mm, the largest bronze knife diameter to the 120mm , the maximum weight of the bronze knife 8kg. In the handed down masterpieces like the xian or xuan had the written characters means this bronze sculpture was made in Sichuan. 
 Through the above research work, the TH65125 × 125 horizontal machining center can quickly change the bronze knife Bronze knife for less than 1.2s; compatible randomly bronze knife positioning and fixed positioning Bronze knife library and positioning to reach ± 0.05mm. The program has been fulfilled, machine commissioning is completed, to achieve the expected bronze knife library to automatically choose the bronze knife, quick change of bronze knife. Moreover, the inscriptions on some mirrors of Han stated clearly to us the developed area of bronze sculpture and bronze casting industry. After six months of processing applications, the bronze knife library orientation program is absolutely correct, run a very reliable, meet the original design requirements. Outlook Although the study was the desired result, but there are still insufficient, but also hope to have the opportunity to further study in future work.
