TITLE
Machinability Characterization in Rough Milling of Mold Steels for Injection Molded Plastic Part Production

ABSTRACT
An economical analysis of the plastic injection market highlights the necessity to increase productivity. Mold steel influences the total cost of an injected part more through its capability to be worked than through its own price. Among the mold manufacturing operations, rough and fine machining are the two most expensive, depending strongly upon the mold steel machinability. The Tool-Work Material Pair Method is applied to compare the machinability of three 300 HB mold steels during rough milling. Based on a half fractional design of experiments, a new model is proposed which takes into account material variation as well as cutting parameter interactions.
