Calculation formula for machining dimensions of taps for internal threads1. Calculation of tap major diameter D0D0=D＋(0.866025P/8)×(0.5~1.3) is the basic size of tap large diameter thread + 0.866025 pitch ÷ 8×0.5 to 1.3.Note: The choice of 0.5 to 1.3 should be confirmed according to the size of the pitch. The larger the pitch value, the smaller coefficient should be used. On the contrary, the smaller the pitch value, the corresponding larger coefficient should be used.2. Calculation of tap pitch diameter (D2)D2=(3×0.866025P)/8, that is, tap diameter=3×0.866025×pitch÷83. Calculation of tap diameter (D1)D1=(5×0.866025P)/8 is the tap diameter=5×0.866025×pitch÷814. Calculation formula for the length of materials used for cold heading forming in various shapes

X in the formula represents the volume value of the required material;L represents the length value of the actual feeding;R/d represents the radius or diameter of the actual feeding.

Everyone is familiar with the thread. As colleagues in the manufacturing industry, we often need to add threads according to customer needs when processing hardware accessories such as CNC machining parts, CNC turning parts and CNC milling parts.

1. What is thread?A thread is a helix cut into a workpiece either from the outside or from the inside. The main functions of threads are:1. Form a mechanical connection by combining internal thread products and external thread products.2. Transfer motion by converting rotary motion to linear motion and vice versa.3. Obtain mechanical advantages.2. Thread profile and terminologyThe thread profile determines the geometry of the thread, including the workpiece diameter (major, pitch, and minor diameters); thread profile angle; pitch and helix angle.1. Thread terms① Bottom: The bottom surface connecting two adjacent thread flanks.② flank: the thread side surface that connects the crest and the bottom of the tooth.③Crest: The top surface connecting the two flanks.P = pitch, mm or threads per inch (t.p.i.)ß = profile angleϕ = thread helix angled = major diameter of external threadD = major diameter of internal threadd1 = minor diameter of external threadD1 = Minor diameter of internal threadd2 = pitch diameter of external threadD2 = internal thread pitch diameterPitch diameter, d2/D2Effective diameter of the thread. About halfway between the major and minor diameters.

For those tricky undercuts, DATRON has a dovetail milling tool and t-slot mill. The dovetail milling tool can bevel and deburr the underside of a part, removing the need to flip the part over for a second operation.

When calculating, the volume X÷diameter÷diameter÷0.7854 or X÷radius÷radius÷3.1416 of the material required for processing cnc machining parts and cnc turning parts is the length of the material.

The geometry of the thread is based on the thread pitch diameter (d, D) and the pitch (P): the axial distance along the thread on the workpiece from one point on the profile to the corresponding next point. This can also be seen as a triangle bypassing the workpiece.vc = cutting speed (m/min)ap = total thread depth (mm)nap = total thread depth (mm)t.p.i. = threads per inchFeed = pitch2.
