针对目前棒料高速动态切割装置支撑半径无法调整，切割精度以及刃磨刀片刃口形状无法控制的缺陷，根据切割装置切割原理，建立了切割模式、刀片数量等切割参数与支撑半径、切割误差的数学模型，并运用曲柄滑块机构设计了新型可调式支撑装置；基于空间齐次坐标变换方法构建了切割刀片刃口形状与切割直径、砂轮安装角度等刃磨参数之间的曲线方程，设计了新型可调式刃磨装置。以刀盘转速、切割误差等作为优化目标，采用MATLAB优化工具箱，对现有双刀双切烟支切割装置的切割和刃磨特性参数进行了非线性多目标优化。根据优化结果，提出了一种新型高速动态跟随切割装置设计方案，该方案采用四刀双切的切割模式。与原装置相比，新装置在切割效率不变的情况下具有更好的切割质量。最后通过仿真验证了该装置的可行性。

According to the insufficiencies of inability to adjust supporting radius and control cutting precision and shape of cutting blade in existing high-speed and dynamic cutting device of bar,the mathematical model between supporting radius,cutting error and cutting parameters such as cutting mode,number of blades and so on were established based on the analysis of cutting principle,and new adjustable support device was designed using slider-crank mechanism.The curvilinear equation between the shape of cutting blade and grinding parameters such as cutting diameter and installing angle of grinding wheel was built by means of homogeneous coordinate transformation,then a new adjustable grinding device was designed. The speed of cutter,cutting error and other parameters were selected as optimization objects,the nonlinear multi-objective optimization of parameters of the two-blade and two-cutting cigarette cutting device was achieved by using the Matlab optimization toolbox.The project of new high-speed and dynamic following cutting device of bar was proposed,and the new device adopts the cut mode of four-blade and two-cutting.It is found that it has better cutting performance and cutting quality when the cutting efficiency is constant,and the device proves possible after simulation.
