Understanding cutting equations | Cutting Tool Engineering
WEBJul 1, 2014 · The following equation is used to calculate spindle speed: rpm = sfm ÷ diameter × 3.82, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and 3.82 is a constant that comes from an algebraic simplifica-tion of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π). You can play around with this ...
Understanding the Identification System for Indexable Inserts
WEBOct 1, 2014 · According to ANSI B212.4-2002 standard, identification of the indexable insert includes 10 positions denoted by a capital letter. Each position (from 1 to 10) defines a characteristic of the insert in the following order: – Shape; – Clearance; – Tolerance class; – Type; – Size; – Thickness; – Cutting-point configuration;

Finish it with reaming | Cutting Tool Engineering
WEBDec 17, 2019 · Before reaming, a hole must be straight. Reamers tend to follow the existing hole, so reaming a crooked hole typically yields another crooked hole. Reaming a crooked hole also can result in an oversize hole diameter. Minimizing runout is crucial when reaming. Consider a 12.7 mm (0.5") reamer with 0.0127 mm runout.
Understanding tapered spindle connections | Cutting Tool …
WEBDecember 01, 2014 - 10:30am. Cutting tools are most commonly mounted in a machine tool spindle using toolholders, which provide the interface between a variety of cutting tool geometries and the common spindle nose. While some tools connect directly to the spindle via bolting, for example, that is unusual. Toolholders simultaneously adapt the t ...

Understanding tangential cutting force when milling
WEBMay 1, 2012 · Torque (T s) that is applied to the spindle, and therefore to the milling cutter, is generated by the tangential cutting force (F t) and can be calculated by the formula: T s = F t × R (1) Where R is a radius of a milling cutter. (Formulas are referenced later by the number in parentheses.) The concept of calculating tangential cutting force ...
Know What You're Tapping | Cutting Tool Engineering
WEBSep 1, 1997 · The key to successful tapping is knowing the true size of the drilled hole. While many factors contribute to tap failure or breakage, one basic, obvious factor is often overlooked - the size of the drilled hole. The problem is, that factor can’t be calculated accurately using traditional tap/drill charts. Many changes have taken place in the years since tap/drill charts were first developed ...
