Flank Clearance and Effective Inclination Angle
Inclination angle β of the cutting edges corresponds to a specific thread helix angle λ and ensures equal clearance angle on both sides of insert.
α - Flank clearance angle
λ - Helix angle
β- Effective inclination angle is achieved by selecting the suitable anvil
Infeed Methods for Threading Operations
Flank Infeed
Radial Infeed
Alternating Flanks Infeed
Flank Equal - Equal depth of cut for each pass
Flank Diminishing - Diminished depth of cut for each pass
Modified Flank Infeed
H - Depth of thread profile (on ø)
D - Depth of pass (on ø)
U - Depth of finishing pass (on ø)
