FASTTRIMSTEEL is a completely integrated CATIA V5 solution to automate the design of trimming tools used in the sheet metal and plastics die forming industry. The solution creates the stock material (casting) and the tool surfaces as separate elements to fully support the engineering and manufacturing process. It furthermore will embed the specific parameters as known in the tool engineering industry. Trimming process parameters will be taken into account. Typical parameters such as shear and back spacing. Collision checks will ensure the trimming tool to actually cut the material instead of touching the material at undesirable places, causing material deformations or bad cutting operations.
