Penetration Test with Worn Button Bits for Rock Drilling.
Shigen-to-Sozai, 1997 Right now button bits are widely used in rock drilling. Considerable effort has been expended by manufactures to increase performance and durability of the button bits. However, most of them were conducted on try and error basis mainly because high level acceleration and vibration in rock drilling prevented accurate sensing and fundamental data ...
