Machining

Grinding machine operators are able to listen to the processes via acoustic emission (AE) monitoring systems and use the information to shorten cycle times and minimize wheel loss from dressing. But, AE sensors need to be positioned to deal with interfering background noise.

Magnetic abrasive finishing can deburr and create highly polished, smooth surface finishes. It can also remove microcracks, recast metal, metallurgical phase changes, visible scratches and damaging residual stresses.

Using mini and micro boring bars effectively in Swiss-style machines requires machine shops to know the types of available bars and the ways to strengthen their cutting edges, reduce pressures on the tools and position them for the most efficient cutting.

With through-tool minimum-quantity lubrication, machine shops may be able to decrease coolant costs and increase productivity and part quality. But, they have to invest in equipment and tooling to achieve those results.

Superhard finishing tools may benefit machined parts via finer surface finishes, greater wear resistance and harder, stronger microstructures. Also, some of the tools can last longer than their conventional counterparts.

Machine shops and other companies discuss the workpiece materials, machine tools and metalcutting processes needed to make the fasteners that keep aircraft and spacecraft together.
