Influences of feed rate on machining precision during grinding metal ceramics blade by diamond grinding wheel 进给速度对磨削金属陶瓷刀片精度的影响
With plc controlling feed speed automatically , this machine , occupying little space and enjoying configuration , is easily operated 本机床结构紧凑,占地面积小, plc自动控制进给速度,操作简便。
A new method , which named reverse shrinking surplus method , has been pointed out based on the fem in order to optimize the speed curve of the spindle 摘要在基于有限元数值模拟的基础上提出了反向最小余量法,用以优化芯辊进给速度曲线。
The optimized speed curve can bring a steady press - down dimension in the process of the ring rolling which could assure high quality products 优化后的芯辊进给速度曲线能保证辗扩过程中始终有理想的每转压下量,从而降低缺陷的发生,提高零件质量。
The feedrate in tangential direction was adjusted by the fuzzy velocity controller for reducing the worst burrs and defects to obtain better quality contour 而模糊速度控制器被用来调节工具进给速度,从而彻底清除较大的毛刺,避免损害工件和刀具,得到理想的加工表面。
