在磨削加工过程中,能否准确而迅速地实现磨具对工件的进给,确保零件的尺寸精度是很关键的问题,它将直接影响产品的质量和生产效率。目前,国内外采用的自动配磨机床和磨削自动检测多采用接触式在线测量。当工件达到所要求的尺寸时,检测装置即传感器发出停止进给的指令信号,这是一个闭环控制的磨削系统。这种系统的缺点是测量机构和控制部分较为复杂,又因磨削加工大都在有冷却液情
In the grinding process, whether the abrasive can accurately and quickly feed the workpiece to ensure the dimensional accuracy of the part is a key issue, which will directly affect the quality of the product and the production efficiency. At present, the automatic grinding machine used at home and abroad and grinding automatic detection and more use of contact-line measurement. When the workpiece reaches the required size, the detection device that the sensor sends a stop feeding command signal, which is a closed-loop control grinding system. The disadvantage of this system is the measuring mechanism and the control part of the more complex, because most of the grinding process in the cooling liquid
