Establishing A Rule Base for the Computer Aided Design of Tooling for the Multi-Stage Pressing of Cylindrical Cups
The development of software for CIM of small cylindrical pressed components has highlighted gaps in the information required for the rapid determination of manufacturing costs and the number of tooling stages and sizes. This paper is an attempt to establish rules based on current industrial practice and past research and on current research being carried out by the Author on the effects of component shape, flanges and wall ironing. Two programs capable of determining the maximum punch loads during first stage drawing and redrawing which include ironing and take into account work-hardening and anisotropy have helped in the development of the rules. Results from current stage design and costing software developed by the Author as part of a Teaching Company project and based on the rules are presented.
