Grinding　burn　detection　is　essential　for　metallic　components　manufacturing　because　grinding　burn　not　only　reduces　the　functional　performance　and　fatigue　life　but　also　affects　the　quality　of　precision　grinding.　Grinding　burn　occurs　when　the　temperature　of　the　workpiece　in　grinding　zone　rises　above　the　tempering　temperature　of　the　material　due　to　inappropriate　grinding　conditions,　resulting　in　microstructural　changes　in　the　surface　and　may　be　accompanied　with　a　reduction　in　strength,　plasticity,　and　hardness,　and　may　introduce　unfavorable　residual　stresses.　This　work　comprehensively　introduces　each　of　the　existing　metallic　grinding　burn　detection　methods　and　discusses　their　applications,　advantages,　and　limitations.　Moreover,　the　trends　of　developing　methods　for　detecting　metallic　grinding　burn　are　also　presented.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
