abstract = "Tool wear characteristics in ultra-precision raster milling (UPRM) include tool fractures, material welding, wear land formation, and sub-wear-land formation. Tool fractures can be imprinted directly on both the cutting chips and the machined surface as a group of “ridges”; material welding can lead to the breakage of cutting chips, which scratches the machined surface and makes the machined surface fuzzy and burred; and wear land formation can make the cutting chips shutter-like at the tool entry side and increase the peak-to-valley roughness of the machined surface. In this chapter, tool fracture wear and its effects on the machined surface are evaluated on-machine by using cutting chips. Through inspection of the location and cross-sectional shape of these “ridges” on a cutting chip surface, a virtual cutting edge of the diamond tool under fracture wear and surface topography considering the effects of tool fracture wear are developed. A mathematical model is developed to simulate the virtual cutting edge and surface topography with two geometric elements, semi-circle and isosceles triangle, used to approximate the cross-sectional shape of ridges. The mathematical model was also utilized to compute the surface roughness taking into consideration the effects of tool fracture wear.",
