The traditional linear function should be displaced by nonlinear function because of the breakage of superposition principle.

由于叠加原理的破坏，主张将非线性生产函数替代传统线性齐次函数。

The relationship between the breakage volumetric strain and the relative breakage can be fitted by a power function.

破碎体应变和破碎率之间存在近似的幂函数关系。

The system have an intelligent control function module and a tool wear and breakage dettction function module which are used to raise machining efficiency and to ensure machining accuracy of CNC.

在功能上加入了智能控制模块和刀具状况监视模块，以此提高数控机床的加工效率，并使加工精度得到保证。
