... a blank holder that descends over the die. Two-point incremental forming is not dieless. However, tooling for ISF can be made of less expensive materials than for stamping, which is still an advantage. In some cases, it is possible to use a partial die ( Fig. 3 , right) to manufacture variations of a part...
