In the machining processes, surface quality of the worked pieces depends strongly on the tool conditions. Tool wear has, by that, a determinant influence on the surface finishing quality of the machined products. Tool wear has been commonly associated with the loss of tool material. Standards, procedures and methodologies have been developed for evaluating tool wear under that idea. How- ever, currently,...
Tool wear concept has been usually related with the loss of tool material. Currently, it must not involve only this way, since wear includes all the changes of the tool properties -geometrical and physicochemical- which modify the initial cutting conditions. Therefore, tool geometrical alterations can also include material addition. Transfer of cutting material to cutting tool during machining process...
