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;
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 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 ...

Tips for controlling runout | Cutting Tool Engineering
WEBAug 19, 2024 — Consider the motion of a crank shaft and its crank pins. This motion is a good way to visualize runout. When a crank is rotated about the journals the crank pins swing in a path that rises and falls relative to the center of the journal. Runout in a shaft or a cutting tool has a similar motion.
