    Opis:
    This work presents the evaluation of wear resistance of milling cutters. The subjects of this chapter were the milling tools commonly used in dental laboratory. Based on the results it was found, that the milling cutter during the cutting operation can easily become the destruction, resulting in the mass loss and in the first 10 hours of milling cutters work with high efficiency. It is suggested that after 10 hours of milling work, in order to ensure high standards of materials processing, milling cutters should be replaced by new one.

    Opis:
    The article reports on a device for book block spines processing that was designed and assembled on a perfect binding machine Trendbinder. The article shows workability of designed device. The authors have developed a methodology for the experimental study of the tractive effort of chain conveyors by technological load, the wireless module for data measurement and software for its processing. Extensive coverage is given to experimental research of the tractive effort of chain conveyors during book block spine processing depending on book block velocity, type of paper from which they are made and setting angle of cylindrical milling cutter relatively to direction of book blocks movement. The authors have examined the change in the tractive effort. The article experimentally confirms that sluggishness of chain drive causes vibration of the tractive effort. This effect can be observed during free-running movement of chain with carriers of perfect binding machine as well as during technological load influence. The article describes that between research parameters the setting angle of cylindrical milling cutter has the main impact relatively on the direction of book blocks movement.

    Opis:
    In machining practice, the selection of the tooling condition of the cutters is an important task for milling operation with better surface quality and material remove rates. This study was therefore aimed at evaluating the influence of the tooling condition, such as the flutes and overhang length, on the machining efficiency of a milling machine by using the machining stability analysis method. Essentially, the machining stability was calculated based on the measured frequency response functions of the milling cutter, while it was also affected by the changing milling tooling path. Therefore, the machining stabilities in different feeding directions, referred to as polar stability boundary, were evaluated to show the strength and weakness of a specific cutter in contouring machining. The current results show that the overhang length greatly affects the dynamic characteristics and the limited cutting depths of the milling cutter. The stability boundaries of the machining conditions can be enhanced by appropriately adjusting the overhang of the milling cutter. Besides, the 2-flute cutter shows a larger cutting depth for surface contouring as compared to the 4-flute cutter, which is expected to increase the material remove rate under stable machining. As a whole, this study provides valuable references for enhancing the machining efficiency through the use of different tooling conditions.

    The article deals with the stress-strain state of the cutters used in the mills of a new design for the restoration of the working surfaces of locomotive wheels. A comparative analysis of stresses in the cutters was carried out using the finite element method, which showed a significant advantage of the new technical solution, the novelty of which is confirmed by the patent.

    Opis:
    The purpose of this article was to evaluate the significance of the influence of five- axis orientation parameters of a toroidal cutter axis and the geometrical parameters of the machined sculptured surface on the intersection of the cut layer in a 5-axis machining. An impact assessment was performed by simulating concave-convex and convex-concave surfaces using a discrete method of direct transformation in a CAD environment. It was shown that only the radius of curvature of the surface in the feed direction and the angle of the tool axis affected the change in the intersection of the cutting layer. Subsequently, experimental tests were conducted that aimed at determining the mathematical models of the influence of these important parameters on the components of the cutting force. The object of the experimental studies was a convex and concave surface of a turbine blade of Inconel 718 alloy. The R300-016B20L-08L Sandvik Coromant toroid cutter was used for the tests. Based on the results of the study it was found that the lead angle in the machining of the convex surface and concave turbine blade should be continuously varied with the change of radius of curvature in the direction of the machined surface profile.
