Force and Acceleration in Turning Using Coated Tools with Flat and Grooved Rake Face
The development of tool wear monitoring systems require a great amount of information about the correlation between the signals from sensors and the tool wear. Several works have presented results of tests carried out in turning operations under different conditions, but there is still a lack of information about operations under practical conditions. This work reports the results from cutting tests with three types of coated tools with different types of rake face, under practical cutting conditions. During the tests signals of force and acceleration in three directions were obtained from turning with fresh tools. The main result was that the spectrum of frequency of the signals of force and acceleration for different tools were very similar. The results suggest that for a system for tool wear monitoring to work successfully with different types of tools, it must have a characteristic design different from those developed to be used with the same type of tool.
