Thedie-making industry does the machining of holes by drilling, reaming, boring, grinding and EDM operations for the fitment of punches, pillars, tool inserts, etc., or assembly purposes like screw relief holes, tapped holes, and riveting holes by using standard fixturing. Normally the hole locations are given in the manufacturing drawing by taking two accurately finished perpendicular datum features. Thesedatum features will be used in machining, inspection,reworks, and they need to be protected from damages. Any inaccuracy in the datum features like flatness, and perpendicularity leads to the wrong measurement or location of the hole, shows an inaccurate assembly. This paper presents the novel method ofusing tooling hole in the manufacturing drawing andillustrate the advantages through experiments. While dimensioning, the concept of tooling hole enhances the tolerance of position in profiles and permits faster machining/inspection activities; thereby increases productivity.
