| Popis: | Investigated the technological process of cutting of printed sheets. For the evaluation of the products were established indicators of quality such as cleanliness, roughness, waviness of the edges, the accuracy of the geometric dimensions and the absence of skew in length and width, the magnitude of asperities of slices. For an objective assessment of these indicators, the proposed corresponding method. From the obtained research results we can see that the quality of cut is affected by the direction of the fibers and the thickness of the material, namely, it can be noted that when cutting in the longitudinal direction of the fibers in the cut quality is much higher.As a result of researches it is established that the most important factors that affect the quality of die cutting are: the geometrical parameters cutting knife (sharpening angle and shape of knife-edge); the thickness of the material that is processed; the pressure of die cutting; square die; the total length of the cutting and creasing knives; the duration of the cutting tool.The result of experimental studies it was determined that the cutting pressure is in direct proportion to the die area and the total length of the cutting and creasing knives. Consequently, the influence of the area of the cutting die and the total length of the die-cutting and blanking knives on the value of the applied pressure, leads to an increase in the cutting pressure with an increase in the area of die-cutting plates. Increasing the perimeter of die-cutting and blanking knives also requires increased cutting pressure.The results of research have shown that the quality of the die-cut is influenced by the direction of the fibers. It is also established a general tendency to improve the quality of the cut when die-cutting in the longitudinal direction of the fibers. |
