  1. 1. Department«Machines and Technology ofWoodworking»Staff members:Ganapolskiy Sergey Grigoryevich, Head of the Department, PhD,Associate ProfessorAgapov Alexander Ivanovich, Doctor, ProfessorRublyova Olga Anatolyevna, PhD, Associate ProfessorVlasov Artyom Vladimirovich, Senior LecturerPh.: (8332) 53-23-94
  2. 2. 1.1 Project nameOptimization of circular saws construction. Investigation of circularsaw blades operating modes and constructions influence on their dynamiccharacteristics.1.2 The essence of the projectDetermination of the optimal construction and improvement ofdynamic stability of circular saw blades to minimize the thickness of the cut,reduce energy costs, improve productivity and quality of wood cutting.

  4. 4. 1.4 AchievementsMathematical model reflecting the connectivity of structuresand geometric parameters of saws with stability factors wasdeveloped.Dependence of the saw blade on its geometrical parametersrigidity was received.Thermal fields in the disk saws were simulated.Saw blade natural frequencies and critical speed wereidentified.Saw blade tension was simulated.Quantity, area location, shape and size of the compensationslots were defined.Optimum number of teeth was determined.Most effective cutting conditions were determined (saw speedand feed rate).An experimental setup for dynamic characteristics of circularsaw blades investigation was constructed and installed.
  5. 5. 1.5 Laboratory facilities- Experimental setup based on the circular saw CA-2A.- Frequency converter Mitsubishi Electric FR-А740-00380-ЕС.- Tachometer АТТ-6002.- Infrared thermometer Fluke 574.- Data acquisition system NI CompactDAQ.- Inductive sensors ifm electronic with analog output.1.6 PartnersProduction and Commercial Company «Makhagoni», Yoshkar-OlaLtd. «Nizhny Novgorod metalworking plant», Nizhny Novgorod
  6. 6. 2.1 Project nameFormation of non-waste technology in the wood studs by coldmechanical pressing.а бв гFig. 1.
