Micro components continue to shrink in size, demanding ever-greater precision and improved handling of parts with sub-micron-sized features. New approaches in micro machining technology include higher-precision systems from traditional micro machining developers, as well as techniques using additive manufacturing processes and semiconductor wafer-scale technology on the smallest of micro parts.

It is reported that, not too long ago, before the current precipitous decline in machine-tool shipments, the number of 30-taper machines that were being manufactured and sold in Japan had surpassed the numbers of 40-taper and 50-taper machining centers.

Until the middle of 2010, first-tier subcontract machinist, JJ Churchill, could produce turbine blades only if they had their fir-tree root-forms preground elsewhere, or if they were subsequently added by another subcontractor. No longer is this the case.

From Boeing 787s to new Navy destroyers, fiber-reinforced composites are gaining in use. As production scales up, more-efficient manufacturing remains a focus. One key to that efficiency is tooling for composites. These molds and forms give the final shape to a part, and are often integral to their final curing.

It is common sense—a vehicle that weighs less requires less fuel to move it. A number of studies show that reducing the mass of a vehicle by 10% results in anywhere from 4.5 to 6% better fuel economy—well worth the effort.

Robotic machining technology has advanced to where it poses a serious alternative to metalcutting applications on more traditional machining centers. With the latest robotics equipment and related software, automation suppliers and robotic system integrators are gaining some traction using robots in many material-removal applications previously done only with machine tools.

Edge finishing is a relatively new term in manufacturing. It’s a new and deeper focus on what many used to call deburring, edge honing, edge preparation, edge prepping, burring, chamfering, or edge blending. Edge finishing goes beyond any of those definitions. Deburring, which is often considered wasted effort by managers, wrongly carries a negative connotation. In reality, deburring and edge-finishing processes add many benefits to parts—they create highly desirable edge quality—the quality most products need.

One of the most cost-effective ways to obtain the benefits of automation is by adding a bar feeder to a CNC lathe or other bar machine. Costing anywhere from about $10,000 to $40,000 depending on configuration, the devices can add hours of untended operating time for part volumes of a few hundred to tens of thousands.

Keeping products clean is becoming a more significant part of manufacturing as standards for cleanliness, deburring, and finish grow more stringent.

Cutting tool maker Shape-Master Tool Co. (Kirkland, IL) needed to expand its tool grinding capability beyond that of its conventional machines or run the risk of losing work to the competition.
