If not, you example, M15x1.5 is 30+3.75+1.5+1=36.25 to the shoulder, not the drill point. The way that we measured the thread was from centerline of the thread crest of the last full thread to the end of gage. If calls for depth / measure depth. I had it at one time, but what is the formula for figuring out how many turns of a thread gauge to determine a depth. We are the largest and most active discussion forum for manufacturing industry. The following formula for the Tensile Stress Area of the (male) screw. Practical Machinist is the easiest way to learn new techniques, get answers quickly and discuss common challenges with your peers. Who cares? The ideal chamfer angle is 30 from the part axis, and shoulder/stock clearance should have a minimum distance of 1.25 to 1.5 x pitch. Below are the equations we use for that: We calculate RminR_\text{min}Rmin to be equal to P8\frac{P}{8}8P. In other words, count approximately 12 threads back from the front of the tap. Is p the actual pitch arrived from 1/TPI? 1. Regardless of what formula you use, you will most likely still have to tweak the first one a littledepending on insert type & how well you touch off your threading tool etc. Definition: Racecar - a device that turns money into noise.

On a manual lathe, I still only use the "plunge method", which is not using the compound at all All suggestions are graciously accepted. If you count the revolutions you need to add 1 revolution to the number that you get cause of the chamfer on the part and the thread gage. This is also the pitch diameter at the gauge plane. For convenience, we use the uppercase letter DDD for metric internal thread dimensions. Were it me, I would have inserted '1' as the value, and run the parts.
