Abstract

This article presents an experimental study examining the effects of technologicalparameters to the ISF process on PVC material such as : tool diameter d, tool step depth z, feed rate fand forming temperature T, thereby the determining the limiting value of angular distortion αmax.

Highlights

  • Polymer materials hold a significant proportion of civil and industrial products

  • Incremental Sheet Forming (ISF) a new sheet forming process has been developed in recent years

  • The ISF technogogy equipment is often a simple frame for clamping sheet material, while the forming is done using a device moving along the contour that is programmed by the CNC machine or industrial robot (Figure 1)

Summary

INTRODUCTION

The traditional technique to produce polymer products based largely on the heating process shaping - cooling, are conducted at yield or flow status to mould and is only suitable for mass production because of high energy and equipment cost. To meet the requirements for reducing cycle time and suitable to produce single pieces, small batch, rapid prototyping, we need to have innovative technologies to make new manufacturing technique flexible. Incremental Sheet Forming (ISF) a new sheet forming process has been developed in recent years. Two types of this technology is Single point incremental forming (SPIF) and Two point incremental forming (TPIF). The ISF technogogy equipment is often a simple frame for clamping sheet material, while the forming is done using a device moving along the contour that is programmed by the CNC machine or industrial robot (Figure 1)
