“…Hybrid machining techniques such as laser assisted [23], magnetic field assisted [24], and ultrasonic-assisted machining [25] have been used to machine hardened steels. As have, cryogenic cooling techniques [26], and special tools such as rotary tools (propelled or driven) [27]. It has been reported that wiper inserts, where the cutting edge is a series of radii rather than a single radius, as in conventional inserts, have been successful utilized for precision hard turning operations [28].…”

This article reports an experimental assessment of surface quality generated in the precision turning of AISI 4340 steel alloy using conventional round and wiper nose inserts for different cutting conditions. A three-factor (each at 4 levels) full factorial design of experiment was followed for feed rate, cutting speed, and depth of cut, with resulting machined surface quality characterized by resulting average roughness (Ra). The results show that, for the provided range of cutting conditions, lower surface roughness values were obtained using wiper inserts compared with conventional inserts, indicating a superior performance. When including the type of insert as a qualitative factor, ANOVA revealed that the type of insert was most important in determining surface roughness and material removal rate, with feed rate as the second most significant, followed by the interaction of feed rate and type of insert. It was found that using wiper inserts allowed simultaneous increases in feed rate, cutting speed, and depth of cut, while providing better surface quality of lower Ra, compared to the global minimum value that could be achieved using the conventional insert. These findings show that wiper inserts produce better surface quality and a material removal rate up to ten times higher than that obtained with conventional inserts. This clearly indicates the tremendous advantages of high surface quality and productivity that wiper inserts can offer when compared with the conventional round nose type in precision hard turning of AISI 4340 alloy steel.

“…This can influence the resulting machined surface. Compared to self-propelled technology, this monolithic tool reduces the surface roughness of the machined surface Rz by 18 µm [25] and the value of Ra parameter is stabilised and less than 0.56-1.83 µm, which was achieved in other research [14]. With ADRT technology and the use of a multi-component tool, the roughness Rz 8 µm [7] was achieved, which is a higher value compared to the highest value measured after turning with the monolith rotary tool.…”

Forced rotation turning appears to be an effective machining method due to higher tool life, time efficiency and acceptable quality. Several studies have been carried out to investigate the basic characteristics of forced rotation machining. So far, tools are used whose design included several components. However, such tools may generate vibrations, which are undesirable in the process. In engineering practice, most vibration problems are solved by reducing the cutting parameters (cutting speed and feed rate), which reduces machining productivity. For this reason, a new type of monolithic rotary tool has been designed that eliminates the design complexity and high assembly accuracy requirements of current rotary tools. Based on the performed experimental research, it is possible to define the influence of cutting parameters on the cutting force. Next, the equation of the cutting force and the resulting roughness of the machined surface was determined. In the introduction, the results of the analysis of machining parameters with a rotary tool were added. The presented solution fundamentally validates the new monolithic tool for forced rotation technology and defines its application for different machining materials.

“…Nieslony és társai munkájában (Nieslony et al, 2020) a felületi érdesség csökkenését mérték az előtolás és a forgácsoló sebesség növelésével, mivel így a forgácsolóerő periodikus változását csökkentették. Ugyanakkor Joch és társai kutatásából kiderül, hogy az alkalmazott nagy előtolás miatt folyóforgács keletkezik, ezért megfelelő forgácstörő alkalmazása célszerű (Joch et al, 2019). A kényszerhajtásos szerszám esetén Olgun és Budak (Olgun and Budak, 2013) bebizonyították, hogy a hagyományos hosszelőtolásos esztergáláshoz képest jobb lesz a szerszámkopás, mert a szerszám éle nem csak egy pontban kopik, hanem a kör alakú lapka teljes kerülete mentén.…”

A megmunkáló eljárások fejlődésével a hagyományosan alkalmazott technológiák mellett újabbak jelennek meg, amelyekkel nagyobb termelékenységet vagy jobb felületi minőséget lehet elérni. Külső hengeres felületek megmunkálására a legelterjedtebben alkalmazott eljárás az esztergálás, amelynél az előírt felületminőség erősen lekorlátolja az elérendő termelékenységet. Ezért dolgoznak ki olyan kinematikai vagy geometriai viszonyaiban más eljárásokat, amelyekkel hatékonyan javítható a megmunkálás gazdaságossága. Ebben a cikkben a szóba jöhető jelentősebb, egyenes vonalú és körelőtolást alkalmazó változatok rövid áttekintése található.
