H＝L₀-L

I. when H is more than or equal to 0 and less than or equal to 5D, the drilling depth is shallow, and the drilling difficulty level is I level;

s51, when the allowance of the cutting fluid is sufficient, the cutting fluid can be matched with all drilling strategies without processing;

s52, when the residual quantity of the chip liquid is less but not reaching the threshold value, the pecking drill cannot be matched with the pecking drill strategy because more cutting liquid is consumed by the pecking drill;
