Problem. The development of automotive technology for various purposes and the
improvement of existing car models, requires a fast and flexible design process. Spatial models of details
and nodes are the starting points for design, and the necessary design documentation is performed on
their basis. When manufacturing parts on CNC machines, it is necessary to quickly obtain a control
program that will increase the accuracy of the product by ensuring the optimal trajectory of the mutual
movement of the part and the tool. Therefore, the creation of a comprehensive methodology for the
design of car parts, their basic inspection and obtaining design documentation is an important technical
task. Goal. The main goal of the work is to determine the rational sequence and basic principles of
computer-aided design, research and manufacturing of car and engine parts, and the development of
mathematical spatial models of surfaces in order to optimize control programs for CNC machines.
Methodology. The approaches adopted in the work for solving the set goal are based on general design
principles. The methods of conducting static and dynamic calculations, as well as spatial mathematical
modeling of the processes of manufacturing parts were also used. Results. A comprehensive
methodology for designing parts of engines and cars has been developed. The main principles of
creating spatial models have been determined in order to achieve their flexibility and simple editing.
Methods of automating the development of drawings and design documentation are described. The
software options for the primary verification of static strength and frequency analysis are considered.
A calculation program has been developed for constructing transient and amplitude-phase-frequency
characteristics. The mathematical spatial modeling of typical surfaces of the camshaft is provided with
the aim of further research and optimization of the development of a control program for processing on
a CNC machine tool. Originality. The defined basic principles of designing parts of engines and cars
provide an opportunity to create a flexible spatial model and more fully automate the process of drawing
up technical documentation. The developed mathematical spatial models of the supporting and working
surfaces of the camshaft make it possible to write a control program with the determination of the
optimal trajectory of the mutual movement of the part and the tool. Practical value. The obtained results
can be recommended when designing car parts and assemblies.
