- improved algorithm for envelope computation in manufacturing simulation
- manufacturing simulation more accurate and robust
- manufacturing simulation much faster now
- manufacturing of gears with pointed tip works now
- some convergence problems fixed
- novel algorithm for envelope computation in manufacturing simulation
- manufacturing simulation enhanced: replaced linear interpolations for
edge-points with exact algorithm (within numerical precision)
- manufacturing simulation more precise and stable
- bug fixes
- removed redundancies from code
- modified to work with newer versions of pythonOCC, NumPy and SciPy
- removed trochoidal root shape generation as it was not correct for helical gears
--> use hobbing simulation for exact root fillet shape instead
- gear hobbing simulation --> exact geometry (external gears only)
- multi-step manufacturing by defnition of blank
- new classes:
"Tool"
"ToothedRackTool"
"Machine"
"GearHobber"
"Blank"
- tooth thickness allowance
- addendum allowance
- acceptance backlash
- tip chamfer enhancements
- bug fixes
- renamed classes:
"SpurGearWheel" --> "CylindricalGearWheel"
"SpurGearPair" --> "CylindricalGearPair"
The following features are planned for the next releases:
v0.13:
- tooth thickness allowance
- tip chamfer enhancements
v0.2:
- geometry generation by hobbing simulation (optional) with standard rack tools (incl. protuberance)
v0.3:
- standard flank modifications and consideration in 3D-geometry
later:
- graphical user-interface
- mesh stiffness calculation
- load-bearing capacity calculation
- bevel gears
- other gears (worm, hypoid, beveloid a.o.)... read more
new features:
- tooth thickness allowance considered
- tip chamfer consists optionally of several points (instead of just two) in tooth form coordinates
- some bug fixes
