Original scientific paper Reducing the manufacturing time is the trend of high precision manufacturing, and the precision of a work-piece is very important for the manufacturing industry. The high-speed motorized spindle is the most critical part and becoming more widely used in the machine tool at present, and its precision may affect the overall performance of high-speed cutting. Most of the studies on high-speed cutting are focused on the cutting force, the vibration of the spindle and effects of the spindle's thermal deformations; hence, how to roundly measure and objectively evaluate a high-speed spindle is an inevitable question. Because the comprehensive dynamic properties and evaluation system of spindles directly affect the cutting ability of the whole machine tool before they are manufactured. This paper presents a comprehensive measurement and evaluation system of a high-speed motorized spindle, which reflect the overall performance of motorized spindle and bases on an international standard Sveobuhvatno mjerenje i evaluacija sustava visokobrzinskog pogonskog vretenaIzvornoznanstveni članak Smanjenje proizvodnog vremena tendencija je u visoko preciznoj proizvodnji, pri čemu je preciznost radnog komada vrlo važna u proizvodnoj industriji. Pri tome je visokobrzinsko pogonsko vreteno jedan od najkritičnijih dijelova koji se naširoko koristi u alatnim strojevima, pa njegova preciznost predstavlja važnog čimbenika u sveukupnoj izvedbi visokobrzinskog rezanja. Mnoge studije o visokobrzinskom rezanju su fokusirane na sile rezanja, vibraciju vretena kao i na efekte toplinske deformacije vretena; stoga, kako propisno mjeriti i objektivno evaluirati visokobrzinsko vreteno jedno je od neizbježnih pitanja. Jer sveobuhvatna dinamička svojstva i evaluacija sustava vretena izravno utječu na rezna svojstva cjelokupnog alatnog stroja, prije no što je proizveden. Ovaj rad prikazuje sveobuhvatno mjerenje i evaluaciju visokobrzinskog pogonskog vretena, koja se odražavaju na sveukupne odlike pogonskog vretena, a koja se bazirana na međunarodnim standardima.

— High speed machine tool is one of the basic needs in catering to a wide range of machining parameters with tight tolerance band. In high speed machine tool many key factors like geometric, cutting force and thermal errors decides the performance of the machine. However amongst these three, error due to thermal deformation is an important factor in influencing the accuracy level of component produced. A survey amongst Indian machine tool manufacturers reveals that there is a strong need to infuse recent technological developments in thermal error prediction and derive methodologies to minimize the same in high speed machine tool. This paper attempts snapshots of a review relating to the errors causing thermal deformations and the modeling techniques developed by researchers and practitioners globally in present scenario. The conclusions made at the end of this paper may not give the full solutions to the problems relating to thermal error but, gives a broad perspective for the Indian machine tool manufacturers’, practitioners as well researchers in India to look in to the research relating to thermal error modeling, analysis and corrective measures.
