Abstract
This article for the printed circuit board (PCB) CNC drilling machine dynamic character and rigidity analysis of Z-axis, With ADAMS motion simulation of the Z-axis program, come to the bit offset of the rig during the drilling process in the X-axis and Y-axis direction, and then use the quadratic elements of the completed prototype data test, the measured data and simulation data compare validation to identify the impact of the motion parameters of accuracy of ultra-high-speed electric spindle drilling. Using ANSYS on the overall structure (in particular, the structure of Z-axis) to optimize the structure analysis, the optimal structural parameters. This article both specific theoretical analysis, but also the experimental verification, through theoretical analysis and experimental validation of the Z-axis structure play an important role to improve the ultra-high-speed electric spindle dynamic accuracy and rigidity in the drilling process.
