Method for grinding complex shapes |
摘要 |
A method of producing a complex shape in a workpiece includes the steps of: i) grinding a workpiece at a maximum specific cutting energy of about 10 Hp/in3·min with at least one bonded abrasive tool, thereby forming a slot in the workpiece; and ii) grinding the slot with at least one mounted point tool, thereby producing the complex shape in the slot. The bonded abrasive tool includes at least about 3 volume % of a filamentary sol-gel alpha-alumina abrasive grain having an average length-to-cross-sectional-width ratio of greater than about 4:1 or an agglomerate thereof. A method of producing a slot in a metallic workpiece having a maximum hardness value of equal to, or less than, about 65 Rc includes the step of grinding the workpiece with a bonded abrasive tool at a material removal rate in a range of between about 0.25 in3/min·in and about 60 in3/min·in and at a maximum specific cutting energy of about 10 Hp/in3·min.
