Development of electronic gear box technology for HNC-8 CNC system
There is a big gap between the domestic CNC system and the imported system in gear hobbing process.The key problem lies in the poor function of the electronic gearbox in the domestic system and the low control precision of the following movement of each feed shaft and the hob spindle.Aiming at CNC gear hobbing machine with six-axis and four-link,the hobbing process is analyzed and the movement relationship model of hob spindle and each feed shaft are established.The characteristics of the open PLC interface of HNC-8 CNC system are studied.Based on the interface with an interpolation period of 1 millisecond,PID control algorithm is adopted to carry out the master-slave following motion control technology and develop the functional module of electronic gearbox for hobbing machine.The hardware and software experimental platform of motion control is built based on HNC-818B/M system to verify the function of electronic gearbox.The test results show that the motion control algorithm of the proposed electronic gearbox is reasonable and feasible,which provides a method for the development of the electronic gearbox of the domestic CNC system.
