Aluminium 6061 is commonly used in manufacturing due to its cost-effectiveness. A total of 23 full factorial designs with four central factors were employed to conduct reliable experiments. The response parameters chosen include Flatness, Straightness, Parallelism, which govern the form and orientation control of Geometric Dimensioning & Tolerancing (GD&T). The spindle speed, feed rate, and depth of cut influence flatness, straightness, and parallelism. Controlling machining parameters is crucial to achieve desired levels of flatness, straightness, and parallelism. Predictive modelling can assist in selecting optimal process parameters. ANOVA analysis was performed to determine the significance of input parameters. Flatness, straightness, and parallelism were measured using a coordinate measuring machine. The predicted values from the model closely match the experimental values. Copyright@ International Science Community Association
