What is Cepstral Analysis?

When doing vibration analysis, the signals received from accelerometers in time waveform are examined in different domains by various mathematical transformations. The most common of these is the spectral analysis that we study in the frequency domain. Spectral analysis generates the vibration signature of the machines as well. When we put the raw signal into […]

Condition Monitoring in CNC Machines and Case Study

For many years, machine tools have been the backbone of many manufacturing industries. Machine tools also play an important role in the global economy nowadays. These machines, which transform complex designs into products by processing materials of different hardnesses, need to be maintained for performance, quality, and ultimately profit. The spindle unit of CNC lathes […]

Hidden Costs in Maintenance Organizations

Most of manufacturing companies conduct several projects and studies on reducing unit costs and gain sustainable advantage in competition in order to exceed its existing situation to an upper level. But it is not enough to just make a machine more efficient. You also need to reduce the cost of it. To decrease the total […]

What is Condition Monitoring?

Condition Monitoring is the process to detect a fault in a machine or equipment by observing parameters such as vibration, temperature and current. Condition Monitoring systems give the opportunity to spot faults that can lead to catastrophic failures and allows maintenance teams to program their schedule. This provide a unique value proposition for taking care […]

Vibration Glossary

Heavy Point: It is the angular position of the unbalance vector at a given lateral position on the shaft. The heavy spot typically does not change with the rotational speed. Received Signal Strength Indication(RSSI): Shows the received signal strength. Larger Rssi value means stronger signal. It takes negative values due to the logarithmic formulation. Subharmonic: […]

How is Fault Detection Performed?

Although the great differences in the nature of maintenance operations in industrial facilities, it contains the processes where similar quantities such as; vibration, temperature, oil quality, etc. are measured. During these processes, data from sensors are converted into different units with transducers and comments are made about system health. RMS (Root Mean Square) is generally […]

Parameter Selections in Vibration Measurement

Vibration measurements are performed to determine the response of machine equipment to both internal and external forces. In mechanical systems, different points of the same equipment are different in geometry, material, etc. That’s why they may have distinctive vibrations due to effects. As an example, when an electric motor operates at high frequencies, frequency of […]

What is Vibration Analysis?

Vibration can be simply stated as a mechanical oscillation around an equilibrium point. In the first stage, vibrations can cause energy wastage and noise, but in later stages; they can even cause the machines to become unusable. This can lead to high maintenance costs, downtime, spare parts costs and even scrapping the equipment you spent […]
