.001 x number of teeth in cutter x rpm example cutting aluminum with a 3/4 key x 10 x 1600 = 16 tiplier number of teeth rpm formula for computing spindle speed is. surface feet per minute factor x 4 = ___ ____ divided by diameter of cutter =____rpm example cutting aluminum with a 3/4 key cutter

Choosing Cutting Parameters/Calculating Cutting Speed and

In order to compute the RPM value of the spindle it is necessary to determine the Dw which is the effective engaged tool diameter. The Dw depends on the geometry of the inserts (ball nose or toroid) and the relative position of the tool against the working piece surface. Example calculation is of Dw is presented to the right. 4.

Basic End Mills Technical Information

Ball end mills, also known as ball nose end mills, are used for milling contoured surfaces, slotting and pocketing. A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations.
