This tool will calculate the profile allowable deviations based in the different quality level of the gear.
Using the module, teeth number, helix and gear width the app calculate the following parameters:
fi``: Single Flank Working Deviation
Fi'': Two flank working deviation
fHa: Profile angle deviation
ffa: Profile form deviation
Fa: Total profile deviation
fHb: Helix angle deviation
ffb; Helix form deviation
Fb: Total helox deviation
fu: Pitch variation error
fp: Single pitch deviation
Fp: Total pitch deviation

All values are in microns.

After having the first calculation performed you can move along the different quality numbers available and compare the values.
The app can also save and share the middle column quality values.
