Tolerance Mate: ISO 286 Tolerance Calculator and Engineering Assistant

Precision is critical in mechanical engineering, machining, technical drawing, and quality control processes. Put an end to getting lost in complex tolerance tables, flipping through pages, and making manual calculation errors. Tolerance Mate is an advanced tolerance and fit analysis tool fully compliant with ISO 286 standards, designed for everyone from shop-floor professionals to university students.

With this powerful engineering assistant in your pocket, you can calculate shaft and hole tolerances within seconds, determine the type of fit, and convert your results into professional PDF reports for easy sharing.

In modern manufacturing, speed and accuracy are essential. Tolerance Mate replaces traditional methods such as handbooks and complex Excel spreadsheets, helping you save valuable time. Whether you are a CNC operator on the shop floor or an engineer working in an office environment, the technical data you need is always at your fingertips.

Thanks to the advanced ISO 286 calculation engine, you can enter the nominal dimension and easily select hole and shaft tolerance classes such as H7/g6 or JS5/h6. The application automatically calculates upper and lower limits, deviations in micrometers relative to the nominal size, and all IT tolerance grades in accordance with ISO 286-1 and ISO 286-2 standards.

The intelligent fit analysis feature allows you to understand not only the dimensions but also the assembly behavior. Based on the selected tolerances, the resulting fit type is identified as clearance fit, interference fit, or transition fit. In addition, maximum and minimum clearance or interference values are calculated, enabling you to assess assembly risks in advance.

With dynamic graphical visualization, hole and shaft tolerance zones are displayed relative to the zero line, allowing clear visual analysis. This feature helps you better understand the logic of fits beyond numerical values and significantly reduces design and interpretation errors.

The professional PDF reporting function enables you to generate well-structured reports containing all calculation results, technical data, and graphical representations. These reports are ideal for quality control, customer communication, and production documentation.

Tolerance Mate supports multiple languages and can be used in Turkish, English, German, French, Spanish, and Arabic. It is a reliable assistant for mechanical engineers, designers, CNC operators, quality control specialists, and students in technical education.

There is no room for error in manufacturing processes. Verify your calculations, improve assembly compatibility, and make your engineering workflows more efficient with Tolerance Mate.
