Speed: As a rule, tapping is slightly faster than thread milling. Depending on the workpiece material, thread depth, and machine tool speed, the 1/4"-20 thread discussed so far might take 4-5 seconds to tap, and perhaps twice that to mill with a full-profile cutter. Yes, single-plane thread mills with their need to make multiple passes are …

Decreasing depth per pass (constant chip area) Decreasing the infeed depth per pass is the most common way to improve the machining result and the First Choice for all thread turning operations. Keep the first pass the deepest and the last pass around 0.07 mm (0.003 inch) Gives an even load on the insert and a more "balanced" chip area.

The forces involved in the milling process can be quantified, thus allowing mathematical tools to predict and control these forces. Formulas for calculating these forces accurately make it possible to optimize the quality of milling operations. Watch this short video from Coromant to learn about the advantages of thread milling.

But this thread milling is kicking my butt! Usually need to adjust deeper and deeper cuts with the thread mill to get it to fit. I draw my part to my major diameter, and under my cut parameters I override my geometry and set it to cut to my minor. Most of the time, by the time my threads fit, my minor diameter is completely out of spec.

Thread milling is the interpolation of a thread mill around or inside a workpiece to create a desired thread form on a workpiece. Multiple radial passes during milling offer good chip control.

The JBO GFG-WFE cut the external thread milling cycle time from 14 seconds to 9 seconds. In addition, because the JBO produces 50,000 to 60,000 parts before indexing (vs. 5,000 to 6,000 parts for the single-point tool), the new technology reduces downtime, while offering 10 times the tool life.

The thread mill can place threads closer to the bottom of a blind hole, and it can machine threads in big holes with ease. The thread mill leaves room for chips to fall away. And the thread mill, unlike a tap, can combine various hole-making operations into a single tool. In short, there is a great deal that a thread mill can do.

Thread milling is used when producing external threads on a milling center or mill turn center. Thread milling produces arguably the best quality thread on aluminum and has other advantages. Thread mills are typically made of carbide, and carbide thread mills offer longer tool life, often within similar cycle times as tapped holes.

The reason the tool is tied to pitch is that the calculation for the trapezoidal thread requires Dmin, Dmaj, P, and H, and 60-deg., where P is pitch, and H, which equals SQRT (3/4) x P, about 0.866 x P. This means that the radial cut equals 3/4 x H = 3/4 x 0.866 x P, which I believe is why the course/fine pitch values increase as the D decreases.
