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 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 ...

Thread milling, simplified | Cutting Tool Engineering
WEBSep 1, 2012 · Harvey Tool offer standard through-coolant thread mills as small as 10-32 and as large as ½-13. Advent’s Hartford gave this example. “Say you need to cut a 6"-12 thread and then a 5"-10 thread. Using an inserted thread mill, all you need to do is change inserts from the 12 pitch to the 10 pitch at $30 per insert.
Tips for getting the most out of a wire EDM
WEBOct 1, 2012 · Wire EDMing requires a range of equipment and complex operations, which can lead to a variety of problems. But the capability and flexibility of the electrical adaptive control technologies that monitor the EDM process—such as flushing, wire tension, automatic wire threading, wire consumption levels, geometry control, surface quality, …
Understanding photo-chemical etching's capabilities and costs
WEBFeb 19, 2022 · The micrometal HP Etch and Etchform technology can process sheets up to 600 mm by 800 mm and down to thicknesses of 3 microns allowing the attainment of impressive yields and therefore keeping unit costs low, said Kern. “However, it is not just the number of parts per sheet that is important when looking at PCE,” said Kern.
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 ...
WEBThe drill point’s geometry must en-sure that the pressure and load on each cutting lip is equal and that chip forma-tion is balanced. This “symmetry” is. The standard 118° included point angle balances the drill’s ability to penetrate mild steels and control the forces that arise when drilling those materials.
Understanding relationship between air pressure and flow
WEBOctober 05, 2017 - 04:15pm. “Pressure” and “flow” are common terms when discussing air compressors, but the relationship between the two is often misunderstood. Pressure, typically measured in psi, determines an air compressor’s ability to perform a certain amount of work at any given point in time. Consider an application as simple ...
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 ...
