The emergence of mold can be traced back thousands of years ago, pottery and bronze foundry, but the large-scale use is with the rise of modern industry and developed. The 19th century, with the arms industry (guns shell), watch industry, ra...
The objective of this research is to develop an effective inspec-tion planning strategy for sculptured surfaces in the OMM(on-machine measurement) process. As a first step, effectivemeasuring-point locations are determined to obtain optimum...
ABSTRACT: A heated mold with temperature above the polymer-softeningtemperature is highly desired in precision injection molding. The elevated moldtemperature reduces unwanted freezing during the injection stage, thusimproving moldability an...
AbstractThis paper completes the design and development of supervisory control system. First, the system design scheme is determined on the base of upper and lower computer after the analysis of structure and function of test 一 bed and MT3...
What Is ERP?When you search for ERP on the web, the sheer amount of information that comes up can be overwhelmingnot to mention a little confusing. Every website seems to have its own definition of ERP, and one ERP implementation can vary wi...
