| Abstract | The development of advanced automobile technologies has made it necessary to develop
or apply new manufacturing techniques to emerging product designs. This techniques require the
use of Computer-Aided Design and Computer -Aided Manufacturing (CAD/CAM) software and
hardware as tools to increase productivity and reduce development time.
This study is an application of the CAD/CAM strategy in the development of a tire mold
master. The Unigraphics ( UG ) software available in the Computer Integrated Manufacturing
Laboratory was utilized to develop the mold master based on engineering drawings and
specifications of a sample tire. In the CAD phase, modeling was done through the use of the
interactive abilities of the software as well as through the development of a modeling program
with the Graphic Interactive Programming Language module of UG. The data points are mapped
on the profile surface and a pattern is developed based on the relations of the data coordinates.
The CAM module was then used to develop the tool paths for the machining phase. The
geometric model of the mold master was machined in three stages. The first stage included the
conversion of the blank block of material into the appropriate tire profile surfaces and mold master
surfaces. The second stage was the finish machining of the tire profile surfaces. The third stage
consisted of the machining of the groove sections which made up the tire tread. The tool paths
source file from the UG software had to be postprocessed, using the UG preprocessor and the
MAHO postprocessor from the Catholic University of Leuven (KUL), to create the correct
Numeric Control ( G-code ) program used in the MAHO 600E 5-axis machining center. The final
product was of good su1face quality, however there are some restrictions on the use of machine
tools in cutting the mold master. |
