Zaznavanje obrabe orodij je sodoben pereč problem v strojništvu. Zato se vse več napora vlaga v optimizacijo in avtomatizacijo odrezovalnih in preoblikovalnih procesov. Povečujejo se tudi potrebe po nadzoru delovanja obdelovalnih strojev, zato je pravočasno analiziranje in odpravljanje obrabljenosti orodja še kako pomembno. Posledično je v proizvodnjih procesih manj zastojev in je tako več časa namenjenega sami proizvodnji in manj odpravljanju nastalih napak. V okviru zaključne naloge smo tako razvili industrijski merilni sistem za spremljanje vibracij vretena frezalnega stroja in naredili časovno, ter frekvenčno analizo s pomočjo programa Excel in Matlab. Tool wear detection is a modern pressing problem in mechanical engineering. Therefore, more and more effort is being invested in the optimization and automation of cutting and reshaping processes. The need to monitor the operation of machine tools is also increasing, which is why time analysis and elimination of tool wear is even more important. As a result, there are fewer delays in production processes and more time is devoted to production itself and less time is spent on eliminating errors. As part of the final assignment, we thus developed an industrial measurement system for monitoring the vibrations of the spindle of a milling machine and made a time and frequency analysis using Excel and Matlab.
