Özet
The main purpose is to produce the machine parts within the defined geometric limits for performing their functions where they are assembled. Production between the tolerance values stated in the technical drawing is very important for rapid assemblying of the shaft-hub connections working with the longevity of the moving mechanisms accurately. Because, production of machine parts at geometric tolerances is required in order to minimize the error-free assembly and undesirable conditions (heating, vibration, wear etc.). For this purpose, AA 7075 T651 aluminum alloy, which is frequently used in aviation, defense, automotive industry where desired geometric tolerance values are so important, is used as workpiece. It was machined by four different coating speeds (100, 200, 300 and 400 m/min), 0.1 mm / 0.5, 1.5 and 3 mm cut depths. The effects of cutting speed on geometric tolerances (cylindricality, circularity, linearity) after processing were investigated. It was observed that the increase of cutting speed is an effective parameter for increasing or decreasing the geometric tolerance values obtained. Increasing cutting speed was resulted in increase of tool vibration, and so increased vibration led to an increase in geometric tolerance values. © 2018 Institute of Physics Publishing.
