Features of Drilling:
1. Friction is severe and requires a large cutting force;
2. Drilling generates a lot of heat, which makes heat transfer and conduction difficult and the cutting temperature high;
3. The extrusion and friction during drilling easily cause cold work hardening of the hole wall, which causes difficulties in the next process;
4. The drill is thin and long, which easily causes vibration when drilling.
