geometric designs and strength checks of force couplings of shafts with hubs (interference fit, clamping connection). application is developed in ms excel, is multi-language, supports imperial and metric units and is based on iso, sae, din, bs and jis standards.

two programs for the tolerance analysis of linear, 2d and 3d dimensional chains, which in addition to the basic analysis (worst case, root sum squares, monte carlo...) also include a solution to some special matters, like analysis of a dimensional chain deformed as a result of temperature change and design of tolerances for a selective assembly. application is developed in ms excel, is multi-language and supports imperial and metric units.

this calculation includes tables and calculations for easy option of fits of machine parts and determination of their dimensional tolerances and deviations. application is developed in ms excel, is multi-language, supports imperial and metric units and is based on next standards: ansi b4.1, ansi b4.2, iso 286, iso 1829, iso 2768, en 20286, jis b 0401.
