ABSTRACT Introduction. Creating of a new process equipment begins with the development of a draft proposal, i.e. the general concept of the design object. A recent analysis emphasized that it is this stage (including exploratory design, specifications development and draft proposal) that accounts for up to 80% of the process equipment manufacturing and operating cost. With the task being complex itself, the mistakes made at the early design stages lead to a sharp increase in labor costs for their correction. Developing the concept of a future hybrid process equipment is a difficult task to formalize. Since multitask machine complex combine various methods of product processing during geometry generation and changing the surface properties, there is a high probability of compatibility problems of the integrated subsystems and components. This is due to the systems design and layout complexity, harmonization of the multitask machine operating characteristics, compatibility of the machine control principles for solving spatial trajectory tasks and ensuring the accuracy of geometry generation. The purpose of the study is to increase the effectiveness of the initial stages of the hybrid metalworking complexes designing based on the structural synthesis of the machine geometry generation systems and the prediction of their technical characteristics. Methods: Theoretical studies were based on the principles of system analysis, geometric theory of the surfaces formation, design of metal-working machines, as well as finite elements method, mathematical and computer simulation. Results and discussion. We present an original methodology for conducting structural kinematic analysis for exploratory design of hybrid metalworking equipment. Theoretical studies have established that the hybrid metalworking systems design efficiency can be increased 6.092... 18.297 times using the methodology of exploratory design. Since the developed design methodology was approved, we proposed the implementation scheme for the hybrid metalworking process equipment. The use of the proposed hybrid machine will increase the efficiency of metalworking in general: the machine parts manufacturing performance will significantly rise owing to the implementation of surface hardening processes by high-energy heating with high-frequency currents and mechanical processing on the same technological site without intermediate re-installation of the workpieces and tools.
