The Online Optimizer

Coming soon: The Machine Tool Genome Project promises to let almost any machine shop use its machining centers more productively. Shops will benefit from tap-test findings without personally tapping any of their own machines or tools.


From Image to Implant

Demo shows custom implant made on commodity-level machine.


How is Large-Part Machining Different?

A shop serving the wind-power industry illustrates some of the challenges particular to machining massive workpieces.


Composites Machining for the F-35

Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some ...


Determining Machining Effectiveness, Not Guessing It

KitchenAid uses Overall Equipment Effectiveness to determine in real numbers the impact individual machine tools have on parts production for its stand mixers. In doing so, it brings actual machining processes closer to ideal ones.


How to Overcome an Acc/Dec Limitation in High Speed Machining

A small pocket in a graphite workpiece limits productivity. Part of the expert’s response is to consider how a lower feed rate might actually be more productive—because the machine will spend more time at the programmed rate.


Five-Axis Volumetric Error Compensation for Large Machine Tools

System simultaneously corrects tool position in multiple axes to tighten machining accuracies on large machines that cut complex shapes.


When Spindle Speed is a Constraint

Though it won’t replace high speed machining, Boeing sees “low speed machining” as a viable supplement to higher-rpm machines. Using new tools and techniques, a shop’s lower-rpm machining centers can realize much more of their potential productivity...


Dial Down or Dial Up?

Vibration analysis may be the machining center’s missing piece. If you haven’t performed this analysis on your high speed machine, you probably don’t know what the machine can do.


The Promise of "High Cube" Machining

Tool paths and a new tool design provide an alternative to high speed machining for achieving high metal removal rates in hard metals on lighter-duty machines.
