Determining the effect of process parameters on surface roughness in two point incremental sheet metal forming process using the Taguchi method

الملخص EN

The main aim of this study is determining the effect of process parameters on surface roughness in two-point incremental sheet metal forming process using the Taguchi method.

The experimental plan and analysis were based on the mixed L18 Taguchi orthogonal array with four forming parameters, tool radius (r), feed rate (f), step over (Δz) and type of support (full and partial support) were analyzed and pyramid shape was used (57°) wall angle.

The influence of the process parameters has been investigated and optimum forming condition for minimizing the surface roughness is evaluated.

The analysis results show that the step over has the highest effect on the surface roughness and followed by tool radius, feed rate and die.

The result shows that the error of predicted accuracy for the surface roughness is (1.2%).
