Quality Gaging Tips - Gaging Tighter Tolerances Is A Different Animal

Tue, 31 Oct 2006 03:39:22 +0350

If you are planning on manufacturing to tolerances of 0.0001 inch or less and have not done so before, your introduction to high order gaging might be an eye opener. Gaging at this level is a very different animal, especially when considering how to measure the new parts you will be producing.

High Speed Machining: The Next Decade

Tue, 31 Oct 2006 03:35:22 +0350

About 10 years ago, Modern Machine Shop published a special issue on high speed machining�the first of what would become a succession of special issues on this topic. Machining centers with higher spindle speeds were becoming broadly accessible then, and something seemed to be happening.

The abbreviation CNC stands for Computer Numerical Control

Tue, 31 Oct 2006 03:26:22 +0350

The abbreviation CNC stands for Computer Numerical Control, and refers specifically to a computer "controller" that reads G-code instructions and drives the machine tool, a powered mechanical device typically used to fabricate metal components by the selective removal of metal.

Ductile-Iron Towers Provide Needed Clamping Rigidity

Tue, 31 Oct 2006 03:19:22 +0350

Holding 0.001-inch tolerances while machining and removing large amounts of material from a brass part is a challenging task when the job is run at 10,000 revolutions per minute with feed rate of 240 inches per minute.

Finishing Process Extends Life Of Cutting Tools And Components

Tue, 31 Oct 2006 03:15:22 +0350

New materials and coating technologies have greatly increased the life and general performance of cutting tools. A new surface finishing technology that originated in the optics industry offers an alternate means for improving the durability of tools made of carbide, cobalt, HSS and PCBN. The Mikronite process, developed by Mikronite Technologies Inc. (Eatontown, New Jersey), is a dry mechanical process that combines compressive forces and abrasive media to polish and strain-harden the entire surface of a tool or workpiece. What this lapping-like process creates is a hardened surface with increased lubricity, smoothness, and corrosion and wear resistance properties. What it doesn�t do is apply a coating or plating to the surface.

SAY HELLO TO THE N54. The twin turbo inline six-cylinder (small turbos fill cylinders 1-3 and 4-6 to boost performance and cut lag), dispenses with the naturally aspirated engine's magnesium/aluminum bedplate construction (found in the 328i and all-wheel-drive 328 xi models) for an aluminum block with cast-iron cylinder liners to better handle the boost pressure.

Machining Under The Microscope

Sandia National Laboratories experiments with turning and milling tools just 10 and 20 microns in size.

Thermal and Structural Analysis Conducted on Hollow-Core Turbine Blade of the Space Shuttle ...

Tue, 31 Oct 2006 03:03:22 +0350

Hot-section components of spacecraft engines are exposed to severe thermal-structural loading conditions, especially during the startup and shutdown portions of the engine cycle. For instance, the thermal transient during startup within the space shuttle main engine (SSME) can lead to a gas temperatures in excess of 3000 �C, affecting the operating life of key components, such as the turbine blades.

A recent project funded by the Department of Energy (DOE) and the National Renewable Energy Laboratory (NREL) involved the study of unsteady blade aerodynamics for large, three-bladed wind turbines at the National Wind Technology Center (NWTC) in Colorado.

Geomagic Introduces Geomagic Blade, Purpose-Built for Turbine Blade Inspection

Tue, 31 Oct 2006 02:59:22 +0350

LAS VEGAS -- Geomagic is demonstrating Geomagic Blade, the first software extension developed specifically for turbine blade inspection, at Power-Gen International in Las Vegas. Geomagic Blade is purpose-built to satisfy the need for greater ease of use, speed and quality in all areas of turbine blade inspection, including aerospace, turbine-generated power grid, propulsion turbines, specialized compression equipment, and others.

Turbine Blade and Endwall Heat Transfer Measured in NASA Glenn�s Transonic Turbine Blade Cascade

Tue, 31 Oct 2006 02:52:22 +0350

Higher operating temperatures increase the efficiency of aircraft gas turbine engines, but can also degrade internal components. High-pressure turbine blades just downstream of the combustor are particularly susceptible to overheating.
