In modern manufacturing engineering, a major challenge is the contradiction between the need to reduce the time required to design and manufacture the products and the increasing complexity of product design. Today's market requires more varieties of products, and consequently the equipment and processes should be more flexible. Fixtures play an essential role in production of high-quality and competitive products in multiproduct manufacturing. The paper describes the ways of increasing of machining efficiency of parts. The principally new constructions of functional modules of modular adjustable fixtures for locating and clamping of workpieces are introduced. Use of the proposed fixtures with the possibility of automatized adjustment ensures the spreading of technological capabilities of CNC metal-cutting equipment, decreasing of preparatory time and setup time, and therefore, assists improving of the efficiency of production planning.

In the article the experimental research of the flexible fixture is shown, which provides sufficient accessibility and allows to perform multiaxis machining of parts, e.g. of levers with one setup. The experimental studies compared with the results of numerical simulation that were previously obtained, confirmed that the proposed fixture design meets all accuracy parameters. The results of experimental studies on the determination of displacements have shown that the values of displacements, determined statically, in the proposed fixtures are smaller than the dedicated ones. The analysis of the data of determination of the frequencies of the proper oscillations in the machining of the levers from steel and cast iron has confirmed that the first critical frequency of the fixture significantly exceeds the similar parameter of dedicated fixture.

Fixtures play an essential role in production of high-quality and competitive products, especially under conditions of multiproduct manufacturing, which requires quickly re-equipment while transferring to the machining of parts of other nomenclature. Nowadays, the multiproduct manufacturing is the basic form of organization in the manufacturing and automobile industries. The article describes the ways of increasing of machining efficiency of parts of automobile industry at the contracting organizations, which are parts of automakers or work closely with them. For increasing the machining efficiency through the use of approaches to intensification of production, and also for performed analysis of locating charts for the majority of parts, which are included to the construction of machines, the principally new constructions of functional modules of modular adjustable fixtures for locating and clamping of parts are used. Use of the proposed construction with the possibility of automatized adjustment ensures the spreading of technological possibilities of metal-cutting equipment, decreasing of preparatory time and setup time, and therefore, assists improving of the efficiency of production planning.
