Lean Production using Casting Simulation to Promote FTR Approach
Abstract: When the talk is about the green production, then intention is to develop a product with first-time-right approach. Foundry desperately needs such production system, as it provides wide range of products. Even the small errors in the inputs (concept, design, raw material, process, etc.) can lead to wasted outputs [1], and invite unwanted cost of reworking. Thus, it is of extreme importance to develop the castings with FTR (first time …
