4. 1.4 Achievements
Mathematical model reflecting the connectivity of structures
and geometric parameters of saws with stability factors was
developed.
Dependence of the saw blade on its geometrical parameters
rigidity was received.
Thermal fields in the disk saws were simulated.
Saw blade natural frequencies and critical speed were
identified.
Saw blade tension was simulated.
Quantity, area location, shape and size of the compensation
slots were defined.
Optimum number of teeth was determined.
Most effective cutting conditions were determined (saw speed
and feed rate).
An experimental setup for dynamic characteristics of circular
saw blades investigation was constructed and installed.

7. 2.2 Project science area
Energy-saving technologies in the woodworking.
2.3 The essence of the project
Manufacturing technology of finger joints using energy-efficient waste-free method
of forming the elements of finger-pressing socket connections for adhesive joints in joinery and
furniture products.
Economic efficiency of the new method is caused by:
- energy intensity of the process reduction;
- environmental performance improving;
- Cost of tools manufacturing reducing.
Nodes for pressing spikes are well integrated into automated production lines.
2.4 Development directions
Possible cooperation with enterprises in areas:
- development of mode pressing elements finger joints in the blanks of wood;
- development of construction equipment for pressing spikes;
- assessment of the quality of furniture parts compounds and joinery production.
