CNC Thread Milling with Fusion 360 from A to Z

Hello everyone, welcome to At-Man Unlimited. We will be taking a deep dive into thread milling, dimensioning, tolerances, CAM, and final inspection for the thread making process. We will first review the dimension of a thread and how they relate to making the thread. Then we will look at the tolerances applied to threads and what controls the fit of a thread. We will take that knowledge and apply it into Fusion 360 to generate thread milling tool paths. After posting the code I will make some sample parts with the mill. Last we will do a final inspection on our sample parts to verify we are meeting the tolerances from the thread specifications. Wiki Page: https://en.wikipedia.org/wiki/Unified...

Formulas used: H=1/TPI * (Cos 30 Deg) External Thread: Ext Diameter = Nominal Thread Diameter - ((Ext Major Diameter Tolerance*Tolerance Factor) + Thread Allowance) Ext Pitch Diameter = (Nominal Thread Diameter - ((H*0.375*2)+Thread Allowance)) - (Ext Pitch Diameter Tolerance*Tolerance Factor) Thread Mill Pitch Diameter offset: The distance from the OD to the Pitch Diameter of the thread. Thread Mill Pitch Offset = Ext Diameter - Ext Pitch Diameter Thread Mill Point Diameter offset: The distance from the OD to the Point of the Root of the Thread. Thread Mill Point Offset = Ext Diameter - (Ext Pitch Diameter - (H*0.5*2)) Internal Thread: Int Diameter = (Nominal Thread Diameter - (H*0.625*2)) + (Int Minor Diameter Tolerance*Tolerance Factor) Int Pitch Diameter = (Nominal Thread Diameter - (H*0.375*2)) + (Int Pitch Diameter Tolerance*Tolerance Factor) Thread Mill Pitch Diameter offset: The distance from the ID to the Pitch Diameter of the thread. Thread Mill Pitch Offset = Int Pitch Diameter - Int Diameter Thread Mill Point Diameter offset: The distance from the OD to the Point of the Root of the Thread. Thread Mill Point Offset = (Int Pitch Diameter + (H*0.5*2)) - Int Diameter One of our viewers Kevin Smolkowski took the time to generate a spread sheet to help with the calculations.
