摘要

CURRENT直线进给轴是许多生产机器中的关键子系统，在生产过程中承担着运输工件和工具等重要职责。因此，部件的工作条件对于生产高质量的产品至关重要。由于这些系统逐渐恶化，因此有必要用状态监测系统来检测这些变化和发生的故障。在本研究中，对进给轴的电机电流进行监测，以确定装配过程中或装配后发生的轴错位。我们使用快速傅立叶变换（FFT）和统计方法进行诊断，以区分不同的未对准情况和进给轴的操作约束。通过模拟左右轴未对准并以不同的速度和

Misalignment Detection on Linear Feed Axis with FFT and Statistical Analysis using Motor Current

CURRENT The linear feed axes are critical subsystems in many production machines and have important responsibilities such as transporting workpieces and tools in the process. Therefore, the component’s working condition is crucial for the production of high-quality products. Because these systems gradually deteriorate, it is necessary to detect these changes and occurring faults with condition monitoring systems. In this study, the motor current of feed axes is monitored for axis misalignment that occurs during or after assembly. We conduct diagnosis with Fast Fourier Transform (FFT) and statistical methods in order to differentiate different misalignment scenarios and operating constraints of the feed axis. Different states are achieved by simulating left and right axis misalignment and operating the table at different speeds and

期刊介绍： ournal of Machine Engineering is a scientific journal devoted to current issues of design and manufacturing - aided by innovative computer techniques and state-of-the-art computer systems - of products which meet the demands of the current global market. It favours solutions harmonizing with the up-to-date manufacturing strategies, the quality requirements and the needs of design, planning, scheduling and production process management. The Journal'' s subject matter also covers the design and operation of high efficient, precision, process machines. The Journal is a continuator of Machine Engineering Publisher for five years. The Journal appears quarterly, with a circulation of 100 copies, with each issue devoted entirely to a different topic. The papers are carefully selected and reviewed by distinguished world famous scientists and practitioners. The authors of the publications are eminent specialists from all over the world and Poland. Journal of Machine Engineering provides the best assistance to factories and universities. It enables factories to solve their difficult problems and manufacture good products at a low cost and fast rate. It enables educators to update their teaching and scientists to deepen their knowledge and pursue their research in the right direction.
