Abstract
The paper presents the concept of a support system for the manufacture of machine spare parts. The operation of the system is based on a reverse engineering module enabling feature recognition based on a 3D parts scan. Then, a CAD geometrical model is generated, on the basis of which a machining strategy using the CAM system is developed. In parallel, based on the geometric model, a finite element model is built, which facilitates defining technological parameters, allowing one to minimize the risk of vibrations during machining. These parameters constitute input information to the CAM module. The operation of the described system is presented on the example of machining parts of the shaft class. The result is a replacement part, the accuracy of which was compared by means of the iterative closest point algorithm obtaining the RMSE at the level of scanner accuracy.

Summary
In line with the latest trends and the idea of Industry 4.0, the objective is to increase automation and autonomy of production. Sensors 2020, 20, 5070 production quality control systems and reverse engineering tools, supporting, for example, CAD model building These tools usually include advanced software installed on dedicated PCs. The second group is software and HMI interfaces dedicated to machine and equipment operators. Tools for designers and technologists have developed over the years, along with the development of computer aided design and manufacturing techniques for machine parts These tools include CAD systems to support the design of parts, CAM systems to facilitate the generation of machining programs and reverse engineering tools used, for example, to identify structural features. Most of these systems are integrated in commercial programs such as Dassault Systèmes SOLIDWORKS, Dassault Systèmes Catia, Siemens NX or PTC Creo.
