i-Machinist vs Fit Tolerance ISO Usage & Stats
iMachinist is a simple to use CNC calculator app that calculates for you the cuttings speed, RPM, feed rate and more for your milling, drilling and turning operations.
iMachinist also includes a database for Hole and Shaft Tolerances and different Threads.
Threads Data:
- Outer Diameter (max/min)
- Pitch Diameter (max/min)
- Core Diameter (max/min)
- Thread Height (max/min)
Tolerance Data:
- Zone (Shaft/Hole)
- Grade (Shaft/Hole)
- Diameter (Shaft/Hole)
Cutting Calculator:
- Tool Diameter
- Cutting Speed
- Spindle Speed
- Number of Teeth
- Feed per Tooth
- Feed Rate

Limits, fits and tolerances calculator has been developed to calculate engineering tolerances of inner and outer features of journal bearings, linear bearings, thrust bearings, bushings, ball bearings, roller bearings, housings, cylinder bores, drilled holes, linear and precision shafts, pistons, etc.
The calculator works in line with ISO 286-1 (2010), ISO 286-2 (2010) and ANSI B4.2 (1978) standards which are based on metric units. According to the input parameters of nominal size and hole/shaft tolerances, size limits and deviations for hole/shaft are calculated and fit type is selected among the clearance, transition and interference fits.
The schematic representation of the fit is also drawn. The preferred tolerances and fits advised by ISO and ANSI standards can be found in the "Supplements" section.
