为了充分发挥刀具的生产能力,必须对刀具在切削过程中的刀刃状态进行自动监测。本文介绍的监测器结构简单,只要在机床主轴的滚动轴承外圈上磨一条小槽,其深度约1mm,就可放置传感器,见图1。它可测出轴承旋转时的应力随时间变化的关系,见图2。这种监测装置既可测量各种内力,如预载荷、弹性液压力、离心力等,也可测量加工时所产生的外力,如进给力、径向切削力与轴向切削力,粗加工和精加工时的切削力等。这种监测器具有以下特点:不需增添其它元件;不会降低主轴的刚度;还可以适用于超载荷时的监测。现举例两则: 1.用于深孔枪管钻的监测枪管钻的价格是昂贵的,但如合理使用,能大大
In order to give full play to the production capacity of the cutting tool, the cutting edge state of the cutting tool must be monitored automatically. This article describes the structure of the monitor is simple, as long as the outer ring of the rolling bearing in the machine tool grinding a small groove, the depth of about 1mm, you can place the sensor, see Figure 1. It can measure the relationship between the stress changes with time when the bearing rotates, shown in Figure 2. This type of monitoring device can measure various internal forces such as preload, elastic hydraulic pressure, centrifugal force, etc., as well as external forces generated during machining such as feed force, radial and axial cutting forces, roughing and fineness Cutting force and other processing. The monitor has the following features: No additional components required; no loss of spindle rigidity; and super-load monitoring. The following two examples: 1 for deep-hole barrel drill monitoring barrel drill the price is expensive, but if properly used, can greatly
