The paper deals with the issues of automation of technological design, for which it is proposed to introduce the concept of a structured reference space of a technological process, which is understood as a special design created on a set of processes used in the manufacture of products, on which their ratio is set for individual subsets of the materialization processes of a product. To describe the reference space of the technological process, a method for solving methodological and mathematical problems is proposed - according to the information image of objects and processes; analysis and synthesis of processes; synthesis of equipment layout diagrams; machine methods of systematization. The latter made it possible to develop a qualitatively new approach to organizing data on technological processes, based on an object model for representing and processing information.

“…The first complex class includes: skins, ribs, frames, stringers, rods, etc., made from a standard semi-finished product (sheets, profiles, profiled plates and thin-walled pipes). The main process of shaping parts of the first class is the process of cold deformation -bending, drawing, stretching, extrusion, etc [13].…”

The article considers the majority of modern foreign and domestic CAD TP, which solve many problems of technological preparation of production. However, in most systems, the used method of automated design of technological processes remains incomprehensible, the existing organizational structure of pre-production is not taken into account, the correction of actual data (cutting conditions, time standards) does not meet the requirements of modern aviation production. The article proposes to actively use the integrated design method in CAD TP systems.

In the literature, a comprehensive assessment of the combined impacts of chemical and mechanical parameters on the properties of thin films grown by SILAR is missing. In this work, ZnO film formation is investigated under variable precursor concentration, pH, withdrawal speed and number of cycles. Interestingly, the produced ZnO films displayed remarkable aspect ratio and morphological variability, ranging from the commonly obtained nanograins shape towards hexagonal nanorods, flower- like rods and nanoneedles, which to our knowledge have not yet been achieved by using single step SILAR process. More particularly, low concentration and intermediate pH and withdrawal rates were favorable for nanorods formation. In addition, increasing the withdrawal speed from 26 to 30 cm·min-1 resulted in a thinner film with improved rod uniformity and reduced crystallite size. This is the first study on the impact of substrate withdrawal speed on SILAR films. Among all studied parameters, the number of cycles was particularly useful for tuning film thickness, while preserving its target shape. In addition, the films grown under a higher number of cycles showed improved film crystallinity and rod orientation with reduced dislocation density, microstrain and bandgap energy. In our conditions, the most suitable combination of parameters required for exhibiting optimized nanorod-shaped coating are: a concentration of 0.07 M, pH of 10.5, speed of 30 cm·min-1 and 40 cycles. In this case, XRD, XPS, Raman and FTIR spectra displayed typical features of hexagonal Wurtzite structure of ZnO with no impurities within the film surface, whereas AFM measured a thickness of 1.4 μm with 243 nm surface roughness.
