(1)某DK7725数控线切割机是采用单板机改造的,执行加工程序时出现正向误差;切割圆时,加工零件呈椭圆形。试机时发现,X轴步进电机在执行加工程序时出现步进不稳情况,用手稍微用力亦可使其停止转动(在正常情况下用手不能使其停止转动)。初步估计是驱动电路问题。由于Y轴步进电机
(1) a DK7725 CNC wire cutting machine is the use of veneer machine transformation, the implementation of processing procedures when the forward error; cutting circle, the processing of parts oval. The test machine found that the X-axis stepper motor stepper instability in the implementation of processing procedures, with a little hard force can also make it stop turning (under normal circumstances can not make it stop turning). The initial estimate is the driver circuit problem. Due to Y-axis stepper motor
