RI of Machine Building Technology

The goal of the Research Institute "Machine Building Technologies" (RI MachTech) is technological provision of solving the most general practical machine building problems. Research Institute focuses its activity on designing pilot samples, appliances, machines etc.

Research Institute MachTech delivers a full range of services connected with design and output preparation of new industrial products. Among the main services are the following: design of computer CAD-models, 3D scanning, prototyping, small-scale production of plastmass articles, casting of steel and non-ferrous metals as well as CNC machining.

• Creating the favourable technological environment for practical SRA results application, rapid and effective engineering development conduction, technological support of SPbSPU scientific units tasks execution;

• Adoption and development of advanced technologies, allowing to cardinally reduce the time-frame and increase the quality of research, development and engineering tasks, especially on the stage of test-piece production and variant research.

Areas of RI of MachTech scientific activity:

Additive technologies – one of the modern innovation technological directions, allowing to considerably speed up solving the wide range of research, development and engineering tasks.

Production: control and design models; functional models, polymeric and metallic prototypes, synthesis casts and synthesis models, master models

Casting technologies

Research Institute of Machine-Building Technologies is carrying out activities on adoption and development of vacuum casting technologies using the synthesis casts and synthesis models for molding production of non-ferrous metals (aluminum alloys, brass, bronze, copper, beryllium etc), construction and stainless steels, as well as polyurethane compositions and silicones. Layer-by-layer synthesis technologies allow to solve the problem of casting parts production, reducing the stage of traditional casting equipment or considerably cutting the time of its production.

Production: non-ferrous metals castings – up to 30 kg, and steels – up to 40 kg, wax (melted) models; polystyrene (burnt out) models; membranous (ceramic) and solid (plaster) casts; silicone casts and polyurethane composition castings.

CNC-processing

CNC-processing activities include technological equipment production, particularly, from the model plastics for thermal vacuum molding, casting production tasks, as well as finishing casting parts processing and integral part production technologies development – from computer modeling on the stage of design to the completed part drive to the TCD.

Production: control programs for machining process on multi-axis machines; casts and shape-generating from the model plastics and lightweight metals, tool set (moulds, punches etc), end items (parts and assembly units) of metals and plastic.

Digitization and Reengineering

Laser, optical, photogrammetric and tactile digital measuring and control systems possession allows to considerably speed up the items geometry control process on all the process steps and provide the new possibilities for speeding up the design work using reengineering or backward engineering technologies – digital model acquisition upon the physical existing sample.

Using the specialized software products allows, upon the digitization results, to design computer models applicable for further work in CAD-CAE-CAM-medium (computer modeling, calculations, production in 3D-medium).

Production: protocols and files of details geometry measurements, 3D-models for comparative analysis with CAD-model and geometrical size drift analysis on relativity with tolerance zones, physical entities digitization.
