Figure 14 compares the wear distribution in the mandrel and die plate. According to the Archards wear model,
the wear coefficient (k), sliding velocity (V) and interface pressure (P) is directly related to wear while the hardness
is indirectly related to wear. To understand the simulated results, it is assumed that the sliding velocity and interface
pressure is constant at each step, the wear coefficient is a constant value set forth by the user based on the literature
review conducted, and the hardness of the coated and non-coated components have been measured at 54 RC and 50 RC. From the simulation results, it is observed that the coated mandrel has a wear depth of 8.95e-08 inch, the coated
die plate has a total wear depth of 2.04e-07 inch; whereas, the non-coated mandrel has a total wear depth of 1.01e-
07 inch and the non-coated die plate has a total wear depth of 2.18e07 inch. In both of the tooling components it is
observed that the non-coated parts have a higher tool wear than the coated parts.
