Popis: | Looking retrospectively at the many years of efforts by a number of researchers to develop a method for machining by cutting of polyhedral parts, it is found that the obtained results were not particularly satisfactory. For this finding, it is not possible to substantiate justify the basis in this paper, but the reason can be briefly indicated. One of the less successful methods has been created, though unintentionally, on the basis of fundamental kinematic cutting schemes (FKCS). The uniform rotary motion B, of the stock is kinematically related to the straight-line reciprocating motion C of the simple lathe cutting tool. Uniform, straight forward motion is also performed from the stock and it is a longitudinal feed movement. This method has some disadvantages: changing the actual angles of the tool during very wide cuts between 0° to 45°; variable size chip which is a source of periodic force loading of the tool and the stock and the correct reciprocating motion is realized by a CNC machine and the deviations from the exact shape being copied relative to the shape of the part surface of the machined area. |
