摘要

It is critical to identify core/cavity and undercut surfaces of molds in partingline generation. A new Ray-Testing approach is presented to detect these surfaces by identifying thevisibility of surfaces. A simple, direct and efficient algorithm to identify surface visibility isdeveloped. Case studies show that the approach is practical and valuable in automated parting linegeneration.
