Modelling and controlling the process of cutting with complex-geometry tools to improve efficiency of mining machines and plants

Constant quality improvement through automation of production processes is an important prerequisite for increased viability mining machines and plants. Factors that limit the cutting machining operations include problem controlling chip formation crushing. Solution this necessitates theoretical description material conditions tools with curvilinear surfaces. The paper describes basic principles modeling process using complex-geometry rake. theory based on concept as a inhomogeneous strain in plastic zone where originates. Based analysis stress-strain state zone, criterial relationships were derived correlate geometric parameters shape curvilinear-rake tool. Prerequisites breaking are stability during cutting, stable chip-to-obstacle contact, high stiffness low flexibility. leading to fragmentation could be found by solving strength problem. Through establishing cause-and-effect formation, curling breaking, new approaches achieving favorable may exerting deliberate impact optimizing flow off established between output tool offer way control various operations. research aimed at creating scientifically informed design codes optimization chip-curling chip-breaking rake
