“…Main demands on designing of fixture are reduced to six groups, considering physical and precision possibilities, requirements to equilibrium state of the system, effectiveness, tool availability, and ergonomics [12]. Moreover, fixture requirements can be separated into two main groups [22,23]: standard requirements (workspace requirements around the workpiece for each process, lowweight fixtures or the ability to use Poka Yoke) and specific requirements (tolerances, costs, short process time and ability for fast reconfiguration).…”

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.

The first-priority directions for modern engineering, especially for multiproduct manufacturing, include the intensification of manufacturing processes, increasing the efficiency of technological equipment, and reducing the time required to implement technological solutions. Fixture design is a complicated and time-consuming process that requires considering many parameters of the closed-loop technological system “machine tool — fixture — cutting tool — workpiece”. One machined part can have several fixture layouts corresponding to all specified parameters; however, their effectiveness differs depending on production conditions. Search for an optimal fixture for specified production conditions is an essential stage of production planning. It has been proved that the efficiency of a manufacturing process should be assessed using single economic indicator — the cost of machining, which considers the costs of time, the total costs for process realisation, and a batch of parts. The paper aims to substantiate the efficiency of manufacturing processes in machining complex parts using flexible fixtures by developing a mathematical model that considers the cost of time, the cost of implementing the manufacturing process, and the batch value of parts production. This approach estimates the efficiency of manufacturing processes for machining complex parts and choosing the flexible fixture layout that corresponds to specific production conditions. It was proved that flexible fixtures could be effectively used for machining small batches of parts with frequent readjustments to new workpieces and short-term machining. A tendency has been established that the higher number of nomenclature of parts contributes to expanding the scope of the effective use of flexible fixtures.

In this study, an assembly fixture called a "Yoke" that is used to assemble different engine types is analyzed. The new engine has some unique parts which cannot be accommodated on the yoke during the assembly. The fouling part is the outlet water pipe which fouls one of the supporting blocks during the assembly. Therefore, the aim of the present work is to effectively accommodate the fouling parts without much modifying the components by using ANSYS. In order to adapt the changing design of new engines inexpensively, this fixture has to be analyzed to identify regions where stress is concentrated. With the aid of the simulation programme ANSYS, this study successfully illustrates the integration of the finite element methods to solve complicated issues quickly. These calculations are exceedingly time-consuming to complete manually, thus simulation software like ANSYS is utilized to complete them more quickly and correctly. The results have been validated by using its mathematical model. The most secure and cost-effective modification for the yoke would be found after thorough investigation in order to successfully accommodate the fouling or clashing elements during installation.
