Tool wear can be caused by: Thermal cracking: Cracks that appear perpendicular to the cutting edge. These cracks are caused by large, rapid temperature changes at the cutting edge. Plastic deformation: When the cutting tool material is softened. This occurs when the cutting temperature is too high for a certain grade. Edge buildup: An accumulation of heavily strained work material on the cutting edge. This leads to dimensional errors and inconsistent surface finish.    Some effects of tool wear include: Increased cutting forces Increased cutting temperatures Poor surface... Show more
