Development of movement crosstalk removal method for 3D elliptical vibration cutting
The three-dimensional elliptical vibration cutting can realize high efficient and low cost of method of optical free surface cutting,whose effective drive form is the stack of piezoelectric ceramics to achieve the vibration in three directions.but the crosstalk phenomenon generated in the process of the piezoelectric movement make the tool deviate the ideal trajectory so that seriously affect the quality of the workpiece surface,damage the tool.Thus a method of removing the crosstalk generated in the three-dimensional elliptical vibration cutting device and its control system is proposed in the paper.The control system model of a three-dimensional elliptical vibration cutting is established,then,the crosstalk data is assumed,using the least squares method to fit the date,crosstalk compensation algorithm is obtained so that the crosstalk removal module can be designed to remove the crosstalk generated the piezoelectric movement,the final section is the simulation-based analysis,the simulation results show that the method can meet the control requirements of the three-dimensional elliptical vibration,the crosstalk of piezoelectric movement can be removed effectively.
