In the event that any type of tool breakage is detected, the HMI program issues a command for an automatic tool change or sends an alarm signal to the NC kernel. An evaluation test in a high-speed tapping machine showed that the developed vision system was successful in detecting breakages of small-diameter taps up to M1.

To obtain the dissipated energy of particles, the motion of the particles and balls was simulated using DEM in a planetary ball mill under dry conditions (Hirosawa et al., 2019).We used an in-house DEM code for the simulation, that is based on the method proposed by Tsuji et al. (1992), and the Hertz-Mindlin contact model was used to estimate the contact force.

mechanisms including chipping, crushing, grinding or splitting. Among these, some mechanisms produce very fine particles with little change in the size of the main element, whereas others produce grains of various sizes. Depending on the resulting fragment size distribution, two main types of degradation mechanisms can then be inferred: fragmen-

Rod, Ball and Pebble Mills. The products from AG or SAG mills typically feed secondary grinding mills with particles that range in size from 5 cm down to below 100 microns (0.1 mm). The final particle size is determined by downstream processing requirements. Grinding is carried out as a wet process with water content between 50 – 70% by weight.
