At the Nirvana Machine Shop on planet Perfection, every workpiece is clamped to a custom-built fixture mounted on a dedicated machine tool. Each workpiece is dimensionally identical to the one before and the one after. All the fixtures are totally automatic—instantly positioning, clamping, machining, inspecting, and releasing the part with the ultimate precision.

Celebrating its 80th year, Kennametal, the Latrobe, (PA), tooling manufacturer, says it has solved the age-long problem of tool stability when drilling in deep cavities, alongside tall shoulders, and past bulky fixtures. Reaching deep inside a workpiece to drill holes can be challenging.

Should the US Copyright Office oversee whether 3D printer operators can use feedstock not approved by their machine’s maker to turn out medical devices or airplane parts, or is that the role of the US Food and Drug Administration (FDA) and US Federal Aviation Administration (FAA), respectively?

Technology is changing ever more rapidly. Sometimes this means topics learned in engineering or technical school become obsolete. Whole new fields emerge within a few years, so that even those with freshly minted educations suddenly find themselves faced with new challenges.

Toolholding for rotating round tools—end mills, drills, and taps—continues to evolve with innovative designs aimed at guaranteeing precision, security, and repeatability. As a result, suppliers of toolholding technology have made supporting the precision, security, and repeatability of shrink-fit, mechanical, and hydraulic toolholding the highest priority.

The evolution to high speed machining (HSM) is continuing and toolholders are playing a crucial role in that process, which includes the interlinking of machining center, programming, high-speed spindles, advanced cutting tools, balancing, and high-performance toolholders in order for shops to take full advantage of HSM.
