The development of energy in our country is one of the good examples, thanks to which it can be claimed that Bulgaria is growing into an industrial country. The study of the stages in this development shows a different attitude towards this industry during the first half of the previous century and then, until the end of the socialist period. Until the middle of the century, energy was extremely underestimated as an area on which the general industrial growth depended, it was neglected financially as a secondary area, for which the differences remained from investments in other directions. A quite natural consequence of this was the weak technical training of the intelligentsia and the inability to develop its own energy production, which led to technological dependence on more developed countries. After the middle of the century, a reversal is noticeable, thanks to which the negative trends are abandoned. There are results that speak for the prioritization of
energy policy.
In addition to being singled out as a separate industry, the energy industry also robs the largest capital funds. The leading understanding is that without the development of energy, there would be no development at all. Undoubtedly, Bulgaria’s great achievements in engineering, metallurgy, transport and other industrial sectors would not have been possible without the successful development of the Bulgarian energy industry.

In the 8th decade of the 20th century, a state program was implemented to automate the entire production in the spirit of scientific and technical progress. More than 160 types of systems for the automation of technological processes have been developed, including individual high-performance machines, industrial robots and manipulators, managed with the most advanced microprocessor technology for its time, subsequently implemented in pilot complex automated workshops and production areas in various economic sites of the country. Prioritizing the production of means of automation of technological processes intensifies machine-building, intellectualizes labor and increases its productivity. Gradually, with our forces and means, experience and a base for further design and implementation of flexible automated production systems in all branches of industry are created. The achieved technical and organizational experience guarantees the membership of Bulgaria in the Permanent Commission on Mechanical Engineering at the SIV and its coordinating role in agreements for multilateral specialization and scientific and technical cooperation in the field of industrial manipulators and robots.

In this work, we present the necessity of using the full mathematics in the industrial branch of machine building of the example of the foundry. Obtaining the necessary structures is accompanied by research work even in micro-foundries, which is provided by powerful and new software products, i. knowledge transfer with computational mathematics, physics and education.
