Micro-milling of fused silica based on

In the proposed method, the chip thickness model for inclined ball end mills was established. Thus, the multi-scale coupling milling process of fused silica was discretized into several nano-scale local cutting processes to accurately calculate the crack. The chip thickness, as the dominant factor to influence the crack of brittle materials, can be used to not only solve the multi-scale
