Abstract

The application of the principles of the geometric product specification (GPS) has increasing importance in the machining industry. The tolerancing process should harmonize the relationship between tolerancing, machining process, measuring and design requirements. The aim of the article is to present the interpretation process and the suggested workflow of geometric tolerances. The dimensional and geometric tolerances are compared, and some critical problems of geometric tolerancing are demonstrated by case studies.
