Investigation of Traces of Interaction between Flap Wheel and Aluminum Alloy Plain Surface

The work deals with the investigation of the model KK751 P80 flap wheel interaction with the plain surface of B95пчT2B aluminum alloy during screw-cutting lathe machining. According to the results, the dependence between the amount of the removed material and the processing modes; and the distribution of the surface roughness and intensity of material removal along of the contact patch were established. The graphs of removal and roughness on the contact surface of the flap wheel and the processed sample are presented. The distribution pattern of the removal intensity on the proceeded surface is shown. The findings show that the value of the achievable roughness and removal are determined by physical-mechanical properties of the processed material and cutting properties of the flap wheel. The analysis of the kinematics and dynamics of flap wheel interaction with the sample surface during processing was made. It was found that the feed direction during surface conditioning that provides the smallest value of the obtained roughness must be opposite to the direction of linear velocity of the wheel on the wheel-to-sample interface, i.e. the feed should be associated.
