Here is an example:<\/p>\n<p>Given the cost of consumable high-precision drill bits and the cost of the drill-bit replacement process, it makes sense to replace drill bits only once their efficacy has measurably deteriorated.<\/p>\n<p>To establish drill bit wear with RIVETINSPECT system, the acquired 3D rivet hole inner surface geometry is programmatically compared with the design specification shape of the rivet hole. The scale of dimensional variation suggests the optimal time to replace a drill bit, before defects start occurring. With this drill-bit replacement approach, operational savings are achieved.<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\"
