摘要
常规的金属切削热弹塑性大变形控制矩阵一般以具体的形变点实现控制,整体精准度较低,进而导致最终的轴向控制误差增大。此次提出金属切削加工热弹塑性大变形控制方法,依据当前变形控制需求,进行热弹温度调试,采用正交处理形式,提高整体精准度,设定正交变形矩阵,设计补偿金属切削热弹塑性大变形控制模型,依据边缘修正的方式来实现大变形控制。结果表明,相比于盾构掘进速度金属切削大变形控制方法、表层改性处理金属切削大变形控制方法,此次设计的金属切削加工热弹塑性大变形控制方法所测定得出的轴向控制误差较小,在热弹塑性技术的辅助下,设计的金属切削加工大变形控制方法的使用效果更加显著、可控,针对性强。
Conventional metal cutting thermoelastic-plastic large deformation control matrix generally realizes control with specific deformation points,the overall accuracy is low,which in turn leads to an increase in the final axial control error.This time,we propose a thermoelastic-plastic large deformation control method for metal cutting machining,which is based on the current demand for deformation control,thermoelastic temperature debugging,adopting an orthogonal processing form to improve the overall accuracy,setting an orthogonal deformation matrix,and designing the Compensated metal cutting thermoelastic large deformation control model,based on the edge correction to realize large deformation control.The results show that compared with the shield tunneling speed metal cutting large deformation control method and the surface modification treatment metal cutting large deformation control method,the axial control error measured by the designed metal cutting thermoelastic plastic large deformation control method is smaller,and with the assistance of the thermoelastic plasticity technology,the use of the designed metal cutting large deformation control method is more significant,controllable and targeted.
