This package contains functions for calculating hole/shaft tolerances and fits per ISO 286
isofits is available on PYPI. Install with pip:
pip install isofits
Import the package:
from isofits import *
See below for a list of function and their usages
upper_tolerance = isotol('hole', '10', 'H7', 'upper') #returns upper tolerance in microns
lower_tolerance = isotol('hole', '10', 'H7', 'lower') #returns lower tolerance in microns
upper_tolerance, lower_tolerance = isotol('hole', '10', 'H7', 'both') #returns both tolerances in microns
mmc, lmc = isofit(10, 'H7', 'h6') #returns mmc and lmc of hole/shaft fit
isoreport(10, 'H7', 'h6') #returns printed report of mmc and lmc of hole/shaft fit
