This is a new one for me. My best customer has just switched to all metric sizing and dimensioning for their parts. I've got to machine a number of things for them this weekend that includes tapping several dozen metric size holes. (M6x1 and M8x1.25) How do you calculate the feed in Inches per...
The tap size chart provides a list of standard size taps, specifying the diameter and thread spacing, for fractional, metric, and screw sizes. The decimal equivalents of the diameters are shown in both English and Metric units.
Tangential velocity on the surface of the tool or workpiece at the cutting interface. The formula for cutting speed (sfm) is tool diameter 5 0.26 5 spindle speed (rpm). The formula for feed per tooth (fpt) is table feed (ipm)/number of flutes/spindle speed (rpm). The formula for spindle speed (rpm) is cutting speed (sfm) 5 3.82/tool diameter.

Using a Metric Tapping Speeds and Feeds Calculator helps prevent tool breakage, reduces machining time, and ensures the longevity of the tap. It provides precise parameters …
The machine must be prevented from forcing the tap to do anything else or the thread quality will suffer or the tap may break. The tension stroke in the Tapping head provides the freedom required to cut the best quality threads with the least risk of breakage. Tapping Systems can be used on any suitable machine tool which has a reversing spindle.
The cutting tools catalogs or our experience tells us the SFM (Cutting Speed) we need to use for a given application. On the other hand, the CNC machine is programmed with the RPM (Spindle speed). Therefore it is common that we need to compute the RPM from a given SFM either for programming or to ensure that the SFM we want to run at is within ...
