Physics · Machining Processes
In a drilling operation, the torque required increases significantly with drill diameter because:
- 1Chip resistance is proportional to the area, which is proportional to Diameter2✓
- 2Flute depth increases linearly
- 3Web thickness remains constant
- 4Cutting speed reduces
Correct answer
Chip resistance is proportional to the area, which is proportional to Diameter2
