The influence of air cutting angle and air cutting time to chip breakage is studied quantitatively. The correctness of air cutting theory is verified by the experiments.
定量分析了间断切削过程中的空切角度、空切时间对断屑的影响，并通过试验验证了用空切理论分析断屑的正确性。
It is also found that the fuel consumption increases with the decrease of firing cycle time, and cutting down the air infiltration will be helpful for saving fuel.
同时， 不同的火焰循环时间和空气渗漏对焙烧的能耗影响较大，降低火焰循环时间将导致能耗增加，而降低空气渗漏量则可极大地降低能耗。
