- Cause: Feed rate is too large
Solution: Decrease feed rate, because too large feeding that will increase the cutting resistance.
- Cause: Point dimensions are not suitable
Solution: Select correct point dimensions, for example: the point angle is small, but the rigidity of cutting material is big.
- Cause: Tool materials is not suitable
Solution: Choose a suitable tool material that means choosing a bigger rigidity of material for making cutter.
- Cause: Relief angle is too small
Solution: Increase relief angle, because too small relief angle will Increase the wear and tear of flank face.
