Comparative Study of Tension Controlmethods for Silicon Ingot Wire Cutting
In order to meet the requirements of low cost,low cutting loss,high precision and high stability of silicon wafer cutting,on the basis of analyzing the advantages and disadvantages of two commonly used wire-cutting tension control methods,ADAMS software was used to model and simulate the spring tension control principle.Based on Simulink and MFAC control algorithm,the ADAMS and MATLAB dynamics co-simulation of electronically controlled tension control was carried out.The results show that the acceleration curve of electrode wire obtained by the two tension control methods had the same trend,and the electronically controlled tension control was better than the spring tension control in terms of speed and accuracy.But the stability was poor.Therefore,a tension control method combining spring and electric control was proposed,and modeling and dynamic simulation were completed in ADAMS.The results show that the device can complement each other to a certain extent.
