Die Science: Selecting the right tool steel

This is a common problem in the forming of stainless steel For example D-2 a high-carbon high-chromium tool steel typically is chosen for forming 409 and 439 stainless The two main elements the comprise stainless are nickel and chromium When the high chrome in the tool steel interfaces with the chrome in the stainless adhesive bonding

Methods for Modeling Complex Geometry

Now that we have studied how to apply a roof and wall element by face and how to create wall geometry and beam geometry by the intersection method on a complex roof surface it's time to apply these new methods to something extremely complex Let's consider using the Revit Cow (Figure 12) as an example Figure 12: The Revit Cow mass family

Definition of Machining or Metal Cutting

Machining is one manufacturing process by which excess material is removed by shearing from a pre-formed blank in the form of chips using a wedge shaped cutting tool in order to get desired shape finish and tolerance Examples include turning milling facing drilling boring knurling grinding etc
