1. Two-speed speed change, wide speed regulation range, not only meets the requirements of high-speed thread finishing, but also has high cutting efficiency and low noise.

2. The machine bed is an integral floor structure, which greatly improves the rigidity of the machine tool. The width of the guide rail surface of the bed is wide, and has been quenched and precision ground by super audio frequency.

3. Quenching precision grinding gears and high-quality bearings to ensure low noise and good sound quality of the machine tool.

4. The spindle box adopts powerful external circulation cooling and lubrication, which not only reduces the temperature rise of the spindle, but also maintains the cleanliness and lubrication of the spindle box.

5. The X and Z axes are directly driven by high-precision ball screws and pre-stressed and tightened, and the nut hanger is an integral structure.

6. The large-size 4-station vertical electric turret enables the machine tool to have high processing efficiency and more effectively ensure the precision of the inner hole thread of the fine turning.

This highly experienced and baffingly intelligent expert has cut threads the mathematical way any number of times but 9.8 out of 10 times he sets the tool, the thread pitch, touches off, sets his zero and cuts taking passes until it liooks like a thread. Then he deburs, measures, and gages taking additional cuts until the thead is in tolerance. Then he notes his settings and goes on to the next thread. No hocus pocus with double depth etc. Go for the end result.

Sorry. What can I say? I'm an analog guy.

Unified and Metric threads are narrowly specified and all the thread parts have been established by their respective standards and all the manufacturing data may be calculated from nominal via mathematical formula. However it takes time to crank through all the numbers and no shop management wishes to pay you to calculate thread data out to a warm fuzzy conclusion. Thus, I "meatball" the thread cutting process making as good an end product as one who spent hours over calculatons.

That said the derivation of standard V thread proportions is a subject worth studying in depth. It leads to a greater understanding of details like tip and root flats, diameter, pitch, and length components when determining thread tolerance and allowance for the various thread classes, and so-on.

For that I reccommend what used to be "Handbook H-28 Screw Thread Standards for Federal Services" originally published by NBS but now it's maintained by NIST. The issue had the most complete formula set. All Unified screw thread standards are set forth in this standard. Machinery's Handbook covers this meaterial in an abbreviated form that varies in quality depending on edition. H-28 by the way comes in three parts. The basic info is on part I, a monstrous array of tables is in part II, and gaging info and acme material is in part III - I think. Better get all three to be sure of complete info.

Many of the gaging manufacturers of the era had appendices in their catalogs and handbooks. You might take a look at Van Keuren Handbook #36 Vol II at the pipe thread material commencing on page 117. There's a lot of data there but not too much that's helpful.

Also try to find a text on mechanical metrology dating from the 50's. I can't ecall the name or author but it was published by Prentice Hall. The book I'm thinking of had extensive discussion on the checking of tapered threads, gaging, and maybe some material on calculation.

Somewhere, sometime, everything in the machinist's trade has been reduced to a standard and published. The trick is where to find it without paying through the nose for a copy from some standards organization. A good techncal library is a great place to start.
