WebJun 21, 2024 · The mill function describes the type of stressing, the transferred stress energy, and the stress number. The material function accounts for the particles’ reaction to the applied stress in form of breakage probability and breakage function, i.e. the size distribution of the fragments. For modelling of comminution processes and its grinding ... Webthe mill, uncouples the breakage rate and selection functions and introduces time as a variable. The ki is the rate ofbreakage of particle size i in the mill, while the bij are the breakage selection functions for the breakage of particles from class j into class i. The …
WebTool breakage detection is achieved by a two step process as follows: 1) The CNC is programmed to touch the probe. The tool touch is programmed as a normal program operation except using the G31 P1 code. The G31 is used to stop probe motion. When coded with axis motion, the motion terminates with the probe touch.
