Technological equipment design based on functionally modular methods is widely used in various technical fields. The designed object can be a technological machine, a production line, or a manufacturing complex. Special attention is paid to the optimization of its structure. The sequence of performing all stages of the optimization synthesis problem is presented in the article. To find a solution to this task, the developer should apply the complete or directed search of acceptable structure options and determine the best one using some optimization criteria to evaluate their quality. It can be simple enough if the designed technical system structure consists of no more than several elements. For example, if the number of alternative elements options is several dozen, it takes much time to accomplish the search correctly. Thus, the greater the number of components considered, the more difficult it is to do all the necessary calculations manually. In this case, machine resources should be involved. This scientific work aims to identify procedures of optimization synthesis that can be automated. Also, appropriate software has to be developed. Our computer program is based on the algorithm of a complete search of all options of the technical system structure. It can process an extensive array of input data and produce all possible and logically permissible results in the form the designer can analyze using the Pareto method to choose the best one. This software can be used for any technical system with a modular structure.

“…1) uses the structural formula XOYZCh in which the symbols of the formula indicate the movable blocks of the machine, starting from the "table-workpiece" block to the spindle block. Such machines with a movable portal (Z axis) provide high-speed processing of housing parts from several sides without part repositioning [19,20]. This type of machine is called "CNC gantry type machine".…”

The design of the main movement drive for a multioperational machine such as a machining center with a modified design of a gear gearbox is considered. A 3D modelling of the machining center drive mechanism with a portal layout was performed in the integrated computeraided design system KOMPAS-3D. Functional extended range of the C3D Modeler geometric kernel when constructing complex geometry of machine housing parts is proposed to use. The procedure for constructing gear rims with high accuracy and geometrically correct tooth surfaces in the CAD environment was applied. At the stage of forming the shape of the tooth of a multivariate choice of the tooth axial shape, it is possible to implement. A new idea to increase the efficiency of the cylindrical gear transmission of the machine speed box based on the modified tooth profile of the gears with inclined-arched teeth is put forward. An analytical apparatus for calculating the design and choosing the radius of the gear-shaping cutting head with known basic transmission parameters have been formed. A comparative analysis for the calculated values of the axial overlap coefficient in an involute helical spur gear and in a spur gear with inclined-arched teeth is carried out with the same engagement parameters, other conditions being equal. Numerical calculations for the modified version of the engagement with inclined-arched teeth compared with the involute helical gear in terms of load capacity have been shown.
