Analysis of the planetary machining of threaded surfaces shows that the thread profile is distorted when using complex motion of the tool and part. As a result, the thread profile in the part’s axial cross section does not correspond to the axial cross section of the initial tool surface. Accordingly, the machined thread profile is distorted by the...
In the past decade, Russian manufacturing has made expanded use of domestic and imported numer� ically controlled machine tools. Therefore, the machining of complex surfaces on such machine tools is of great interest today. The cutting of internal threads with planetary tool motion is one such method. Thread cutting is a complex and laborious proce...
The growing industrial use of numerically controlled machine tools is associated with the introduction of innovative tool designs, such as TMC threadcutting mills produced by KENNAMETAL, VARDEX, and others), which are equipped with removable polyhedral hard-alloy plates and used to machine internal threads. The adoption of such mills on up-to-date...

... Increasing the efficiency of drilling is possible by changing the geometric parameters of cutting and sizing part of twist drill, by selection of cutting modes and using of methods for increasing wear resistance of the cutting part [1][2][3][4][5][6][7][8][9][10][11][12]. Vinogradov's A A and Rodin's P P researches showed that the correlation between the type of chip and the variation in the cut chip thickness throughout the cutting edges of the drill. ...

... Резьбофрезерование получает все большее распространение среди способов изготовления резьбы [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Это связано с широким использованием оборудования с числовым программным управлением (ЧПУ) и такими достоинствами процесса, как: ...
... Fang et al. [16] investigated the effect of built-up edge on the cutting vibration in machining aluminum alloys, and a quantitative relationship between the built-up edge formation and cutting vibration was established. Kosarev et al. [17] reduced the vibration by mills equipped with replaceable hardalloy plates when cutting internal threads. In addition, chatter vibrations have been studied, which is the origin of large and devastating relative displacement between tool and workpiece [18,19]. ...
... To ensure continuity of the front angle and the gullet space between adjacent teeth it is required that the grinding wheel end is always parallel to the vector of the resulting linear velocity of tool's rotational motions about its own and vertical axis [16,17] (Fig. 1). That is, no cropping or incomplete formation of a helical chip groove is provided with the following law by changes in the tilt angle of the grinding wheel: ...
