Finishing processes of molds and dies are known throughout industry as skill-oriented and out highly automated. This paper presents a mathematical model with ten geometric parameters to represent sixteen types of mounted grinding tools specified in ANSI B74.2. The mounted grinding tools (wheels) have been widely used in conventional mold and die finishing industries. These grinding tools now are used in an automated surface finishing system (ASFS) based on a CNC machining center attached with an electrical grinding spindle. Due to the variety of geometric types of mounted grinding tools that are used in automated surface finishing processes, compensation of tool contact point to tool origin becomes imperative to achieve the desired surface finish of molds and dies. The developed geometric model can be used to compensate the mounted grinding tools by integrating into finishing path generation in automated surface finishing processes. The ball-nose tree-type and spherical grinding tools have been used in this paper to verify the developed geometric model.
