The principle can be applied to trochoidal tool paths, and I recently wanted this feature while doing some trochoidal material removal, but its not a function specifically of trochoidal milling. Not the way I want it anyway.
I thought of this ages ago, but manual milling of all things brings it back to mind. I sometimes rough mold blanks on the manual mill. A common operation is to remove approximately 0.24 inches of material from most of a blank leaving a boss at one end to be rounded over for a hinge. In this roughing operation I usually use a 1/2 inch 3 flute end mill with bright aluminum geometry. I can take 80% axial width of cut about as fast as I can turn the handle in the climb pass, but only about
40% feels good in the conventional pass to return. On this machine doing this I get no chatter and the floor of the cut is decent. Better than good enough for roughing. "Rapiding" back takes the same amount of time as cutting back, so its just wasted time to only climb cut this roughing operation.
None of my CNC machines (currently under power) are as powerful or as rigid as then manual mill. None of them are high dollar VMCs either so when we get to the obvious answer I'll tell you why its less desirable. The basic principle in the previous paragraph can still apply.
It might be desirable to be able to set the step over differently for climb cutting vs conventional cutting in roughing operations. Some might argue that you just do whichever works best and rapid back to the start. The Speedmasters only rapid at 150ipm and the Tormach 1100S3 only rapids at 110ipm. That travel time adds up over the course of an operation. It can cost you hours. Now if I could adjust climb and convention step over (and or feed rate) within a single roughing operation in many cases the material removal rate would be LOT higher than only climb cutting or only conventional cutting depending on the application.
On a recent job in a large deep pocket we found that climb milling didn't chatter with a reasonable chip load, but it chattered like crazy when conventional milling. It sure would have been nice to adjust the conventional cut independently and cut in both directions instead of spending a third of the cycle time performing rapids. I have not really seen this mentioned much in machining circles. Guys who use a half million dollar machine owned by their boss's bank just count on those stupid fast rapids, or their machine is so heavy, powerful and rigid it doesn't matter. Hobbyists just live within their limits and puff up their chest saying, "SEE! it can cut metal," defensively. I'm somewhere in between.
