基于机床做功量的监控系统开发

Development of Monitoring System Based on the Work Load of Machine Tool

在分析机床维护保养不良是影响机床可靠性的关键因素的基础上,将一种新的可靠性思想———用户监控维护方法引入数控机床可靠性研究领域中。提出了机床定功维护的概念,并以丝杆螺母副维护保养为例,建立了丝杆螺母副与电机做功关系的数学模型。给出了主轴电机功率的获取方法,并通过对数控系统西门子840D进行二次编程,开发了基于用户角度来提高机床可靠性的用户监控维护系统。该系统在数控机床上的成功应用为机床可靠性的研究提供了一种新的思路和方法。

On the basis of poor maintenance of NC machine tool is the key factor of influencing the machine tool reliability, a new method which called User Monitor and Maintenance was introduced, and a creational concept of maintenance based on work to the field of NC machine reliability research was put forward. By the example of maintenance of ball screw and nut, the math model between the ball screw and nut, and the work of electromotor was established. The method of obtaining power of main spindle motor was given, and the System of User Monitor and Maintenance based on secondary development of NC Simens 840D system by users to improve the reliability of NC machine tool was developed. The successful application of the system on the NC machine tool provides a new method and idea for the research of NC machine tool＇s reliability.
