【摘要】 针对碳纤维预浸坯的结构特性以及在传统切割中存在的问题,研究设计了一种超声波切割装置,以PC+运动控制卡作为超声波切割机构的控制系统,伺服电机控制超声波切割刀在工作台上的运动。重点介绍了对C轴刀具旋转运动的控制,以保证超声波切割刀的刀刃方向始终与切割图形的切线方向一致。通过上位机编程软件编程,PMAC运动控制卡发出指令到伺服驱动器,驱动电机进给运动,从而实现自动化切割。该切割系统和传统切割方式相比,具有效率高、切割质量好等优点。更多还原

【Abstract】 In the light of the structural characteristics of carbon fiber prepregs and the problems existing in the traditional cutting process,an ultrasonic cutting device was designed using PC+ motion control card as the ultrasonic cutting mechanism control system and using servo drive to control its knife’s movement on the worktable. This paper focuses on the control of the cutter’ s rotary motion in C axis,which will ensure the direction of ultrasonic cutting knife blade following the tangent direction of cutting graphics. Automatic cutting can be achieved by the upper computer programming software making programs and the PMAC motion control card issuing instructions to control servo drive driving feed movement of motor. Compared with the traditional cutting method,the ultrasonic cutting system has higher efficiency and better cutting quality.更多还原
