Synopsis:

Suject SD describes methods, practical case studies and measuring instruments used for machine tool diagnostics. Vibration measurements are the main topic discused in the frame of the subject. Special care is taken to standards ISO and ČSN used for practical measuremets.

Requirements:

basics of vibration theory

design of machine tools

Syllabus of lectures:

Introduction into vibration measuremnts

Vibrodiagnostics I - spectra

Vibrodiagnostics II

Signal alanyzing techniques, FFT envelope

Bearing diagnostics

Sensors and measuring instrumentation

Geometric accuracy of axes of rotation

Balancing techniques

Thermodiagnstics, diagnostics of electromotors

Syllabus of tutorials:

Vibration od machine tool in accordance with ČSN200065 (ISO 10816-3)

Measuring of vibration spectra, filtration

Diagnostics of machine tool spindles

Geometric accuracy of axes of rotation

Operational deflection shapes (ODS)

Typical failures and their pattern in FFT spectras

Balancing

Study Objective:

Aim of this subject is to familiarize students with standards ISO and ČSN during practical measurements hold on the real machine tools. A practical handling with measurement instrumentation is the next goal of the subjest.
