The correct locating of workpieces in fixtures is an important step for ensuring the accuracy of machining. The choice of the locating chart for the specified conditions depends on the size and quality of the locating surfaces, as well as on their location. The concept of safety zone is introduced for the identification places in a workpiece, which are not desirable to use at the design stage for the contact with locating and clamping elements. The method of computer-aided positioning of functional elements of modular fixtures is proposed considering design and technological parameters of workpiece’s surfaces. Integration of this technique into the computer-aided fixture design system is an effective solution for reducing time for designing fixtures for drilling-milling-boring machine tools, as well as for increasing the quality of fixtures’ configuration. This approach is sufficient for fixture design for parts machining in automotive, pump, oil and gas industries. A mobile application is developed for providing positioning and visualization of the mechanical system “fixture – workpiece” using the technology of augmented reality. Case study is included to demonstrate the effectiveness and capabilities of the developed methodology.
