The Time is Right for Cermets | Cutting Tool Engineering
WEBMar 1, 1996 · It has taken some time, but cermet inserts are finally finding their place as turning tools in American machine shops. U.S. users are learning that for high-speed finishing cuts cermets perform better than even coated carbide inserts, and their use reduces machining costs. In one application, for instance, a manufacturer switched from coated carbide to TNMG332 cermet inserts to turn 1043 steel ...
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;
The fundamentals of industrial sawing | Cutting Tool Engineering
WEBJuly 28, 2017 - 07:15am. Extracting computer-generated shapes from CNC machines with high-pressure water and high-energy lasers can be appealing, making it is easy to forget about more-traditional cutting methods such as sawing. Sawing is one of the most common manufacturing processes in a machine shop. It is versatile, simple and reliable.
In the (Small) Groove | Cutting Tool Engineering - ctemag.com
WEBFeb 1, 2009 · A grooving tool with a 1mm leg would require a safety factor of 0.2mm between the leg and the component. Theoretically, then, the tool could cut a 0.8mm-deep groove. However, with only 1mm of leg, the tool will probably be too weak to actually cut a groove of that depth, and would be limited instead …
Design engineer’s guide to photo chemical etching
WEBAug 4, 2017 · Tolerances are a key consideration in any design and with photo etching varies dependent on the material thickness. For materials between 0.025 mm and 0.250 mm the minimum standard tolerance achievable is ±0.025 mm and between 0.250 mm and 1.5 mm ±10 percent of the metal thickness. In …
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 ...
Shop Operations: A fresh look at 1-2-3 blocks
WEBAug 25, 2017 · Simply put, a 1-2-3 block is a common shop setup tool usually made of hardened steel that measures 1" thick × 2" wide × 3" long. Machinists use the blocks for myriad machine and inspection setup tasks. The blocks are accurately ground to size and orthogonal geometry, within 0.0002" (5µm), with the intention of trusting them as de facto shop floor setup standards without regard to delicacy ...
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 ...
