Sandstone grinding/pounding tools: Use-trace

2018-8-1  For example, stone-on-stone grinding often leaves distinctive wear traces in the form of deep furrows and highly levelled grains leaving the interstices un-altered (Adams, 1989a, Adams, 1993; Dubreuil 2004:1616). Stone-on-stone wear may originate during the manufacturing stage and/or during actual use (e.g. grinding stone axes).

microscopic usewear on each upper and lower grinding stone during each phase of use (Figures 6-8). The first peel from each grinding stone (Peel A) documents the unused surface. Other peels are from surfaces at various later stages of the experiments (see Tables 1 and 2 be-low). All tools were hand used in one dominant direction

Tool wear monitoring for micro-end grinding of

2009-6-21  In assessing the influence of tool wear effect, the dynamic grinding model treats the tool wear mainly as the size change in the grinding wheel, and its grinding performance is assumed insensitive to this size change (Biera et al., 1997). This is proper for conventional grinding, as its tool size is so large that its grinding performance will not degrade too much until a significant amount tool wear
