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 ...


What is the Best Process for Machining a Small, Precise Hole in Aluminum?

This small hole is actually large enough that any of three different processes might be used.


Why Do Cutting Tool Charts Give Recommended Parameters in a Broad Range?

The answer has to do with the differences from cut to cut, as well as the differences that make some shops more capable than others.


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.


When to Mill Keeps Changing

Technology improvements steadily expand the range of tool and die parts that justify high speed machining.


Video: 80-Insert Crankshaft Cutter

This video footage shows a massive crankshaft being machined on a turn-mill machine using an 80-insert cutter nearly 5-inches in diameter.


How Do You Maximize Tool Life In Aluminum?

Boeing experts say climb vs. conventional is not the key. They recently answered a question submitted through our Aerospace Machining Zone, saying the key to tool life is actually chatter control.


Cutting Tool Cost Comparison Utility

 Here is a calculator for measuring the actual cost of a cutting tool, once tool life and productivity are figured in.
