摘要
Magnesium alloys are used as advanced structural materials for producing machine components for the aircraft or automotive industry. The machining of these components involves the risk of uncontrolled ignition during machining operations and production of fine-grained chip fractions causing the wear of kinematic pairs in technological machines. Given the operation of machine tools, the determination of a method for assessing risk based on determining a safe milling range and suitable operational parameters seems justified. The paper presents the results of investigations on chip fragmentation, chip mass and dimensions. Based on these parameters, we determine effective and safe regions with respect to operation of machine tools. The experiments are performed on magnesium alloy AZ91HP, one of the most widely used casting alloys.
