超砥粒ホイールを用いた研削加工の最適化

SFドレッシング法におけるツルーイング性能の向上

抄録

A　Grinding　is　a　method　to　form　a　shape　by　rotating　a　wheel　rubbing　against　the object.　Dressing　for　the　grinding　wheel　is　consisted　of　two　processes　:　truing　and sharpening.　When　super-abrasive　wheels　are　used,　it　is　very　difficult　to　form　in the　truing　process.　In　order　to　improve　the　process,　our　laboratory　has　developed called　SF　(Side　Face)　dressing　process.　It　is　to　use　a　vertical　rotary　dresser travelling　across　the　diamond　wheel　with　the　same　speed　condition. This　paper　reports　the　improvement　of　truing　efficiently　through　the　analysis　of SN　ratio.　As　the　ideal　function,　it　was　considered　that　the　wear　of　the　diamond wheel　is　larger-the-better　and　the　wear　of　the　dresser　is　smaller-the-better.　The total　of　these　two　SN　ratio　was　used　for　the　analysis.　As　the　result,　the　improved compared　with　current　condition　was　estimated　as　13.72　db　and　confirmed　as 12.66　db.
