Background

Tapping is one of the processes that most requires attention in the industry, due to the stage in which it occurs and its characteristics. In the case of tapping, it is common to use components and equipment with less rigidity, which compromises the dynamic behavior in several situations and can lead to process distortion or failure.

Purpose

The objective of this paper is to study the dynamic behavior of tapping in relation to several characteristics of the process.

Methods

The dynamic behavior of the force signal was used to evaluate the process, varying the cutting parameters and the clamping system of the workpiece.

Results

The experimental results indicate that the floating system did not present a good dynamic behavior at high cutting speeds, this greater application of vibration is due to the resonance due to the combination of oscillations under forced and natural vibration.

Conclusions

The natural frequency of the floating fixture system influenced the behavior of the axial forces. The increase in cutting speed resulted in a direct increase in the axial force vibrations as its frequency came close to the natural frequency of the system. Through dynamic analysis of the axial force signal observed the dynamic characteristics of the process and the machine tool. This allowed the dynamic evaluation of the system through the measurement of force signals generated in the threading process.

敲击轴向力的动态行为

背景

由于窃听发生的阶段及其特征,窃听是行业中最需要注意的过程之一。在攻丝的情况下,通常使用刚性较低的组件和设备,这会在某些情况下损害动态性能,并可能导致过程变形或故障。

目的

本文的目的是研究与过程的几个特征相关的攻丝的动态行为。

方法

力信号的动态行为用于评估过程,改变切削参数和工件的夹紧系统。

结果

实验结果表明,浮动系统在高切削速度下没有表现出良好的动态行为,这种更大的振动应用是由于在强迫振动和自然振动下的振动相结合而产生的共振。

结论

浮动夹具系统的固有频率影响轴向力的行为。切削速度的增加导致轴向力振动的直接增加,因为其频率接近系统的固有频率。通过对轴向力信号的动态分析,观察了过程和机床的动态特性。这样就可以通过测量攻丝过程中产生的力信号来动态评估系统。
