摘　　要：分析了滑枕热变形的起因,介绍了控制和减小热变形的方法,然后通过设计热变形测量装置,采用实验研究和实践相结合的方法,用霍尔式位移传感器测量落地铣镗床滑枕热变形伸长量,通过西门子840D数控系统SIMATIC功能对机床滑枕热位移进行了补偿,减小了滑枕热变形误差,提高了机床的工作精度。In this paper,the cause of ram thermal deformation was analysed,and the method for controlling and reducing the thermal deformation was introduced.Through designing the thermal deformation measurement device,and by combining the experiments research with practical study,the thermal deformation of floor type boring and milling machine＇s ram was measured by Holzer type displacement sensor.Then,the ram thermal deformation was compensated by SIMATIC function module of Siemens 840D.The ram thermal deformation error was reduced,and the work accuracy of the machine tool was enhanced.
