Friction and Tool Wear

• The last trends in tool condition monitoring are focused on the development of on-line indirect methods

• There are several in-process indirect measurement systems based on different types of sensors or a combination of them

• The most commonly applied sensors are vibration and acceleration, load and power or acoustic emission and force

• Among them, acoustic emission and force sensors are the most widely employed due to their interesting performance

• However, there are different critical points in the set up of these systems that can be improved in order to obtain better results

• This work is focussed on the analysis of some of the most critical problems involved in the experimental set up of tool condition monitoring systems based on acoustic emission detection and analysis
