 · Chip thickness at the trailing edge is smaller than the hone, so the cutting edge removes material inefficiently, which increases friction, cutting forces, temperature and wear rate. Endres also found that the common brush honing process tends to overhone the tool corner radius, or trailing edge, producing larger hones on the corner than on the leading edge.
