20 Figure 2.3 Residual stress profiles for different flank wears [Tonshoff el al 1995] Figure 2.4 Residual stress profiles for different tool geometries and workpiece materials [Ramesh et al 1999] 21 2.2.5 Tool Wear Abrasion, adhesion, diffusion and chemical reactions are dominant wear mechanisms in hard turning which affect the wear pattern for: flank wear, crater wear, thermal shock, cracking, notching wear and chipping [Chou 1994, Huang 2002]. Flank wear of tool inserts can significantly increase the cutting force and cause damage to the workpiece. So it is very important to estimate flank wear of tool inserts. Tool flank and wear can be estimated by several methods including a fuzzy neural network model [Chungchoo 2000, 2001], an acoustic emission model and a computer algorithm incorporating force, wear rate and cutting temperature models [Chryssolouris 1987]. The fact that tool wear effects the cutting force is well known. Tool wear sensing using cutting force signal obtained from tool dynamometers during the machining
