Laboratory „Automated Technological Design“

Automated design of technological processes for manufacturing of products using the licensed software VERTICAL of the company ASCON is performed in this laboratory.
Main activities: selection of initial billets, machines, tools and cutting regimes from electronic libraries; automated production of technical documentation.

• lathe machines - Т200 with SINUMERIK S840 DSL system and СР161 with ЕТА17 system;
• machining centers МС032 and CМ040 with the system Fanuc 6M-B;
• industrial robots REM10-12, PM6400, РБ231, РБ211, etc.

Students study the configuration, kinematics, structure, operation and applicability of machine tools with CNC and industrial robots. They develop programs for parts processing, set up technological and tooling equipment, conduct research.

Laboratory „Dialogue Programming Systems”

The laboratory was established with the active support of SIEMENS Ltd. – Bulgaria, which provided specialized software packages “SINUTRАIN”, “SHOPMILL”, “SHOPTURN” and „Virtual machine”. Students learn the most modern methods and tools for dialogue programming with CNC machines. They develop and simulate the operation of programs for processing of complex prismatic and rotational parts.

Laboratory„Instrumental Equipment“

The laboratory is equipped with modern tooling and measuring equipment for testing and optimizing the processes of cutting with defined and non-defined cutting edge. This laboratory has been equipped with the support of CERATICIT - Bulgaria.

Educational Production Center

The established on the territory of the Department of Mechanical Engineering Equipment and Technologies Educational Production Center is functioning within the High Tech Center Ltd. At the Educational Production Center, advanced technological processes are developed, set up and applied, technological and tooling equipment is designed with the direct involvement of students, who conduct their educational-production practice and participate in real production. The Center maintains active relationships with engineering firms in the region and the country and works on their requests.

Laboratory 5210 – “Processing of Metals by Plastic Deformation”

This laboratory is equipped with machines for carrying out mechanical tests of metals and for assessment of their technological properties. Students from different degree courses are introduced to the construction, installation and principles of operation of die instruments. They have the opportunity to compare the old (conventional) methods of plastic shaping and the new (intensified) ones.

Laboratory 5211 – “Metal Casting”

Students get acquainted with the properties and main methods for testing of molding materials and mixtures; to the characteristics and types of casting molds and the ways of producing them. They also make mold cores using modern methods.

1133А – Materials Science Laboratory

The laboratory is equipped with a metallographic microscope which explores the structure of metals. In it students are introduced to the relationship between the chemical composition, structure and properties of metals, alloys, non-metallic engineering materials and on this basis – the field of their application.

The laboratory is equipped with furnaces for heat treatment of metals. By a given part drawing students determine the range of heating, the cooling medium and the type of heat treatment. The modes of heat and chemical heat treatment of most commonly used engineering materials are also determined
