Simulator, graph program and self-assessment
tolerances, deviations and fits NBR 6158

Brazilian standard based on ISO / DIS 286-1 and ISO / DIS 286-2

Simulator, graph program to calculation of tolerances, deviations and fits NBR 6158 (Brazilian standard based on ISO/DIS 286-1 and ISO/DIS 286-2) for self-assessment of your knownledge

Roll down until the enf of the page to interact with the simulator and self-assessment for calculation: Deviation and tolerance. It provides the maximum and minumum dimensions of the hole and of the shaft, using the standard ABNT NBR 6158 (Brazilian standard based on ISO / DIS 286-1 and ISO / DIS 286-2), it also calculates the deviations, the tolerances and the adjustment, ele também calcula seus afastamentos, as tolerâncias e o ajuste, besides presenting a representation with no scale of adjustment of the shaft and hole.

Take a look im the image below, and how it is easy to use. Just imput the nominal dimension and select the deviation and the tolerance of shaft and hole. Automactily, the simulator will provide the the tolerance, the deviations, and the maximum and minimum dimensions of the adjustment and spaces and (or) the minimum and maximum interferences.

Type the nominal dimension in millimeter and click in the deviations and tolerances grade of the hole and shaft (ex. 125 H7-h6)

see how it is easy to use the Simulator, graph program and self-assessment

The program: "Simulator, graph program and self-assessment. fit, deviations and tolerances ABNT NBR 6158" was foi designed to give support to professor's performance in regular classes and to give support for learning itself, giving feedbacks in real-time. The simulator was not tested in order to garantee 100% of the results assording with standard NBR 6158, this way:
