Abstract
The paper deals with experimental facilities including adaptive type multi edge head with elastic guides for fine turning. The adjustment of the head cutting edges positions in the process of machining is performed by two- directional electromagnetic drives with micro controller based on intellectual control. The algorithm and software control program to solve the problem of automated accuracy supply of the parts machining technological processes are given. It is established that the proposed head operation makes possible to provide high level response to momentary changes of cutting force components at cutting edges as well as cutting forces stabilization. It is also possible to control the feed change of each cutting tool and to obtain the vibration less high precession cutting process of fine turning. The experimental research was carried out to prove the efficiency of cutting forces equalization, when using the constructed facilities on the base of control algorithms, that cover either the resultant axial forces maintenance or summarized displacement of cutting edges. The conducted analysis allows to conclude that using of multi edge head with cutting forces equalization mechanism influences on the efficient increasing of the technological machining system rigidity. This in its turn makes possible to decrease the influence of cutting forces components on the part manufacturing accuracy. The parameters of the machined work pieces roughness as well as the geometric shape accuracy were investigated using profilometer-profilograph of 296 model and roundness measuring machine BE-20A. As a result this research testified the multi edge head working efficiency and adequate correspondence of experimental and theoretical investigations (the error is from 10 to 30%). It makes possible to decrease the chip-cutting time and non-productive machine time and to increase of the machining productivity while providing the necessary machined surface quality.
