对特殊工件的磨削加工过程进行抽象、建模和求解.将砂轮和底座看成刚性坐标系,将工件所在的下台、中台、上台看成可平移旋转的变换坐标系,基于工件母线方程,以砂轮和工件母线相切为紧约束,运用平面坐标变换理论设计加工方案,并对方案进行了误差分析,最后考虑砂轮的实际磨损,分别提出圆柱形和轮式砂轮修整磨削策略.
Abstracted, modeled and solved the grinding process of the special workpiece.The grinding wheel and the base are regarded as the rigid coordinate system, the downgrade, middle platform and the upper platform of the workpiece are considered as the transformation coordinate system which can translate and rotate, , The tangency between the grinding wheel and the workpiece bus is a tight constraint. The plane coordinate transformation theory is used to design the machining scheme and the error analysis is carried out. Finally, considering the actual wear of the grinding wheel, the dressing strategy of cylindrical and wheeled grinding wheel is put forward respectively.
