The El Reno tornado moves northward, then becomes nearly stationary/looping near 1-40 for ~400 s from 2328 to 2335 UTC, and then moves eastward for several minutes until becoming nearly stationary or looping again while dissipating at 2345 UTC, suggestive that the larger circulation is itself moving in a trochoidal fashion inside a larger mesocyclone.
Automatic path generation for trochoidal and plunge milling are features on the more sophisticated controls, requiring only the entry of a few values on an "open groove" type setting.
In a trochoidal strategy, the cutting tool follows small-radius, overlapping circles in areas where the tool would otherwise be buried.
There is also a trochoidal machining option, which avoids full-width cuts when the cutter encounters heavy engagement.
Mastercam Mill Version 9 software from CNC Software delivers high speed pocketing and increased machining options, including full trochoidal machining (moving the tool in small circles that can nibble out the entire pocket so the tool is never buries), according to the company.

The patented expander technology, called a Trochoidal Gear Engine[TM] (TGE), is more efficient, cost effective, and durable than existing technologies.
High-speed pocketing, for example, cuts to a trochoidal (looping) motion which nibbles out the entire pocket to ensure that the tool is never buried.
The technology behind the products, the Trochoidal Gear Engine[TM], is a simple, efficient, and cost effective expander used in an organic Rankine cycle.
The use of PowerMILL s trochoidal strategies to program the operation gives a number of benefits, in particular high material removal rates with lower, and more consistent, cutting forces as can be seen in the video at https://www.
