摘要
针对现有的硬脆材料加工与超声振动加工实验教学设备的技术困境,基于超声振动辅助线锯切割工艺的优点,设计了一种新型的超声振动辅助线锯切割硬脆材料平台并将其应用于实验教学。设计了加工试验并对比了不同切割参数(锯丝线速度V_(s)、锯丝进给速度V_(w)、工件旋转速度n_(w))与超声振动对线锯切割工件表面粗糙度的影响,验证了该实验教学平台及超声振动辅助线锯切割工艺的有效性。该平台结构紧凑,使用与维护成本低,灵活地将线锯切割加工与超声振动加工相结合,能有效地填补相关专业在制造类课程中关于硬脆材料加工与超声振动加工的实验教学装置技术的空白。
Aiming at the technical difficulties of the existing experimental teaching equipment for processing hard and brittle materials and ultrasonic vibration assisted processing,based on the advantages of ultrasonic-vibration-assisted wire sawing technology,a new type of ultrasonic-vibration-assisted wire sawing platform for hard and brittle materials was designed and applied to experimental teaching.The processing experiment was designed and the effects of different sawing parameters(the reciprocating velocity of the wire saw Vs,the feed rate V_(w),the rotation speed of workpiece n_(w))and ultrasonic vibration on the surface roughness of the workpiece were compared.The effectiveness of the experimental teaching platform and the process of ultrasonic-vibration-assisted wire sawing is verified.The platform has a compact structure,low cost of use and maintenance,and combines wire sawing with ultrasonic-vibration-assisted processing.It can effectively fill the gap of experimental teaching equipment technology about hard and brittle material processing and ultrasonic-vibration-assisted processing in mechanical manufacturing courses of relevant majors.
