gear teeth, the die is initially designed to a non-plane parting face structure as shown in Fig.2(a) (dieⅠ). However, the tooth tip of the die is fractured after about 100 hits ( Fig.3(a)). As a trial... as that of the original die. In production practice, it is time-consuming to develop a die for forming a new gear part. The trial and error method usually take 30-40 d to accomplish the die development......
with the metal to be formed. In this work, the trial ceramic die was prepared by sintering the green of the ZrO2-TiO2 with the polyvinyl alcohol(PVA) in the atmosphere. The low-cost commercial yttria...
