1. Introduction 1. Introduction

Incremental sheet metal forming (ISF) is a flexible, versatile, and economic manufacturing technology in which the dedicated tools and dies are completely or partially eliminated. Instead, it relies only on a simple stylus forming tool featuring and end-mill shape to develop and form highly complex shapes Jeswiet et al.(2005), even with asymmetric geometries, compared with traditional sheet metal forming methods (e.g., deep drawing, hydroforming, bending) Incremental sheet metal forming (ISF) is a flexible, versatile, and economic manufacturing technology in which the dedicated tools and dies are completely or partially eliminated.
