Surface Roughness in Incremental Sheet Metal Forming of AA5052

Abstract:

This paper presents the effect of forming parameters on the arithmetic mean surface roughness (Ra) of aluminum alloy built by a single-point incremental sheet metal forming process. Three investigated parameters are feed rate (12.5, 25 and 50 in/min), depth increment (0.015 and 0.030 in), and wall angle (45° and 60°). The results show that wall angle, depth increment and its interaction play an important role on the surface roughness, while feed rate has little effect. The optimal forming conditions for minimum surface roughness are feed rate of 25 in/min, depth increment of 0.015 in and wall angle of 45°.
