Machining cycle
Taper threading
The same threading capability, applied to a tapered surface


Cycle form: internal taper threading shown — start and end hole diameters set the taper angle, live 2D toolpath simulator on the right.
Taper threading mirrors the regular threading cycle — multi-start, direction, lead-in and lead-out — but lays the thread path onto a cone instead of a cylinder.
Who needs this cycle
Needed for tapered thread connections (for example, tapered pipe threads) where a regular cylindrical threading cycle doesn't apply.
Key form parameters
- •Start and end diameter of the taper
- •Taper angle
- •Thread pitch
- •Number of starts
- •Lead-in and lead-out
Verification status: this cycle has been verified with an air/step run on the author's machine; verification with an actual material cut has not been done yet.
