3D TOOL WEAR LAB

Problem Summary:
This lab will demonstrate how to set up the model data for tool wear computations in a
typical cold extrusion process. The objective is to understand the tool wear behavior of
extrusion punch. Tool wear is mainly dictated by process conditions and materials used.
This model illustration assumes that the coefficients used have been calibrated under
steady wear conditions for a given process involving a set of die and work piece materials.
These coefficients should be used with caution and for qualitative evaluation only when
applied to any other process or material conditions. Currently DEFORMTM system has
Archard’s model and Usui’s model apart from the user routine support. Typically
Archard’s model is widely used for forming applications and Usui’s model is used for
machining applications to compute insert wear. Archard’s model can used with either
isothermal or non-isothermal runs. On the other hand Usui’s model can be run only be
used with non-isothermal run as it requires interface temperature calculations as well. For
both of these models the die (or insert, in case of machining) should be meshed, with
appropriate boundary conditions and inter-object relations defined. This lab will glance
through the complete problem setup with emphasis on tool wear part of the data and
assumes user is familiar with the typical problem setup procedures.
