EFFECT OF PUNCHING SPEED AND DIE WALL BEVEL ANGLE ON PRODUCT QUALITY DURING INCREMENTAL SHEET FORMING PROCESS

Abstract

Incremental sheet forming technology (ISF) is currently being used in the production of sheet products because of its outstanding advantages such as flexibility, the ability to create many complex shapes, and low cost for producing small quantities. However, the forming ability of ISF depends on many factors such as forming punch speed, punch step, product wall tilt angle, forming punch radius, etc. Testing by directly forming with ISF often leads to costly and time-consuming work, so using simulation software to predict the results before implementation is extremely necessary. This study focuses on determining the influence of two parameters: forming punch speed and tilt angle of product's wall on the forming process, identifying the largest thinning areas, predicting cracks on the product, and then applying simulation software to survey the conical product forming process. This research not only helps to reduce product defects but also expands the application of ISF in current industries
