An Experimental Study on Effect of Process Parameters on Surface roughness for Deformation Machining Stretching Mode

Abstract

Deformation Machining is a metal forming process where thin floor like structure is produce by milling, and then the forming of this thin floor is being carried out with single point incremental forming tool. In this process the deformation may be perpendicular to the axis of tool known as bending mode or may be along the axis of the tool known as stretching mode. Forming of thin structure is always a difficult task, and literature shows significant work in the area where sheet and plate like structure is form by die and press. Surface roughness plays crucial role in functioning of part. In this study objective is to study the effect of different process parameters on surface roughness of the part produced. Experimental set for the process is developed and design of experiment is used to carry out for the experimental run. Surface finish of the form feature is measured using surface roughness tester. ANOVA is used to find out significant process parameter affecting the surface roughness. Results shows that incremental step depth and feed rate have more significant effect on the surface roughness.
