数控机床进给系统热变形分析及补偿抑制对策

摘要

After discussing the measures to restraint both temperature rise and heat-deformantion of ball screw, an approach of resolving temperature rise and heat-deformation is offered. And this kind of approach has a guiding role to acceleration & deceleration characteristics of ball screw pairs' promotion and a rapid tracing ability about movement, guaranteeing system rigidity of ball screw and axial rigidity of lead screw pairs, and as well as to reduce the starting and stopping of deformation caused by moment elasticity%对抑制滚珠丝杠的温升及热变形进行了探讨,提出解决温升和热变形的方法.对提高滚珠丝杠副的加(减)速度特性及对运动指令的快速跟踪能力,保证滚珠丝杠轴系的系统刚度和丝杠副的轴向刚度,减小起动和停止瞬间弹性变形具有指导意义.
