Tools with rotary cutting edges – classification and terminology

Abstract

Na tle stanu wiedzy, analizy literatury i własnych doświadczeń w badaniach narzędzi z ostrzami obrotowymi przedstawiono stosowaną terminologię i klasyfikację tych narzędzi w procesach obróbki frezowaniem, toczeniem, rozwiercaniem i powiercaniem. Na podstawie tej analizy zaproponowano skorygowaną i ujednorodnioną terminologię i klasyfikację. SŁOWA KLUCZOWE: narzędzia z ostrzami obrotowymi, narzę-dzia z ostrzami samoobrotowymi, narzędzia z wymuszonym obrotem płytkiResearch focuses on unconventional tools with the rotary edges (RET -rotary edges tools) type self-propelled rotary edges tool (SPRET) and driven rotary edges tools (DRET). Based on the analysis, corrected terminology and classification are presented.

Face rotary turning tools (FRTT) in high productivity process

“…material machinability, process parameters, blade geometry or cooling method. Those conditions (especially related to optimal edge geometry resulting from its angular setting in tool holder) were relevant for previous designs with rotary edges tool -RET type SPRET [2]. Design of different type of tools RET, i.e.…”

“…DRET (driven rotary edges tool) with own drive for blade rotation in body was complicated and expensive. For this reason, these tools have not found any application in the industry [2][3][4].…”

“…its settings -in the layout and working system (fig. 2) (for over 150 years the angular position of the tool relative to the workpiece in the turning process remained fixed [2]). The main difference in relation to e.g.…”

“…In this case the only limit is ratio of blade radius to expected workpiece geometry. At the same time, round edges, even in in their classic field of application are sensitive to vibration, as confirmed by years studies on tools RET [2][3][4]. Although, this tools are characterized by high endurance and wear resistance, but their tendecy to vibration is difficult to handle, because dynamic properties of machine-tool holder-workpiece-tool (MHWT) system are specific and hard to identify.…”

“…During the research on the possibility of self-rotating tools applications [2][3][4], marked with the acronym SPRET (self-propelled rotary edge tool), for cylindrical surface machining on milling machines equipped with special device for workpiece fixing and rotation (fig. 1) was checked the tool design, which use the bearing of machine tool spindle for their rotation.…”
