About this data
Each 6mm stainless twist drill bit used for DAQ has 4 edges. Images of the bit were taken after each 3 paths (also possible for lower or higher paths) over work piece using Keyence VHX-S15F microscope. Data has been structured into three classes for flank ware level ("Sharp", "Usable" and "Worn")
To ensure high surface quality and low cost during production milling process, the tool ware has to be monitored constantly. However, manual inspection can be highly time consuming and erroneous. Simple automatic solutions are often not sufficient, since the tool ware behaves usually non-linear and depends on many factors.
The data can be employed in machine learning methods for indirect determination of tool ware. The data is generated on a CNC machine in a multi interpolation manufacturing process and 3 tool ware classes were identified and labeled by experts.
