Optimization of Process Parameters for Reducing Surface Roughness Produced During Single Point Incremental Forming Process

Abstract

Single point incremental forming (SPIF) is rapidly progressing technology for obtaining rapid prototypes and manufacturing small batch of sheet metal components. Experiments have been conducted at room temperature on a Vertical Machining Centre using a spherical headed tool and an appropriate fixture for machining a desired size of Aluminium sheet with application of grease and lubricating oil during operation. A methodical optimized framework has been designed for the prediction of most appropriate process parameters with a view to attaining minimal surface roughness by means of Grey Relational Analysis (GRA).
