摘要：
In this work a study of the influence of cutting speed and feed on different geometric deviations (straightness, parallelism, roundness, and circular run-out) of dry turned UNS A97075 (Al-Zn) cylindrical bars has been carried out. The experimental data have revealed a low sensitivity to change of these deviations with cutting speed and feed, within the range of cutting parameters evaluated. In addition, several parametric models have been developed from the experimental results. These models allow predicting the behavior of these deviations as a function of cutting parameters applied. In order to do this, different parametric models (potential, exponential, and polynomial) have been tested. For all analyzed geometric deviations, the exponential model has shown the best fit to the experimental data.
