In stand-alone tests of both rotors under the same discharge volume, the newly developed tooth profile reduced the friction of the rotor by 34% compared to the conventional trochoidal
tooth profile (Table 2).
In a trochoidal
strategy, the cutting tool follows small-radius, overlapping circles in areas where the tool would otherwise be buried.
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.
NX offers specific roughing features such as corner rounding, corner slowdown, and trochoidal
milling patterns that ensure that the tool is never buried in the material.
EdgeCAM uses this intelligence to create effective toolpaths for cycles such as Roughing, now" with the Trochoidal
option, removing full width cuts on the toolpaths and allowing high feed and speeds to be programmed, reducing cycle time.
tool path employs overlapping circles that are half on and half off the material.
Mastercam Mill Version 9 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 buried.
machining option avoids full width cuts when machining by generating toolpaths that follow the normal model offset roughing toolpath, but automatically switch to trochoidal
motion when the cutter encounters heavy engagement.
V.9 delivers high-speed pocketing and increased machining options for milling, including "trochoidal
" machining (moving tool in small circles to nibble out the entire pocket); more than 16 new programming and automated features to reduce programming and turning time; new wirepaths with easy new interfaces for faster programming for wire EDM; and an even more seamless line between solids and machining for NC programmers.
