![Page 2: Draw die wizard](https://reader033.vdocument.in/reader033/viewer/2022061601/556dde15d8b42a524e8b484b/html5/thumbnails/2.jpg)
The Note • This system was developed for projection
of dies which working parts are made on cavityless casting.
• The equipment (forming machine ) on which dies are designed should be strictly double operation, i.e. have internal and external slide blocks.
![Page 3: Draw die wizard](https://reader033.vdocument.in/reader033/viewer/2022061601/556dde15d8b42a524e8b484b/html5/thumbnails/3.jpg)
The positive sides from application of system is:
Maximizes productivity through automation design Maximizes productivity through automation design process.process.
Automation of tedious and time consuming tasks.Automation of tedious and time consuming tasks. It is much easier to visualize the 3D model than on a 2D It is much easier to visualize the 3D model than on a 2D
drawing.drawing. Significantly shortens the design time.Significantly shortens the design time. 3D modeling is more accurate and useful than with 2D
design.

Requirements shown to operation in system*
• The user should know a base training course on work in system Unigraphics (the nobility of a basis of modelling, drafting, and work in a context of assembly).
• The user should have an experience of a die design.• Presence of a database of standard elements applied in
die design.• Presence of a database of equipment (forming machine ).
