SUMMARY
 
The proposed project will be developed in the following directions: investigations on CNC machines from woodworking and furniture industries of Bulgaria, analysis of the production process, the work, it characteristics, tools, their possibilities and principles of work as well as the whole complex of problems which the bearing determine of the new technical resolution. The CAM systems of graphic programming for CNC machines will be investigating, theirs application, opportunities, a method of work, options, computability with different CAD products and requirements towards the hardware for some CAM systems as well.
The research works will be carried out in the production conditions of the firms “GYUL” Ltd. – Asenovgrad, “MOSKOM” Ltd. – Novi Han, University of Forestry – Sofia etc.
By this project that is proposed to be realized in the frameworks of 2 (two) years, will be consolidated and developed the experience on automatic operation with modern CNC machines for working of wood and wood materials with advanced information technologies, for increasing performance and accuracy of mechanical processing.
The results will be exploited as in the practice, so in the instructional process as well.
On the ground that will be developed curriculum for educational qualification degree “Master” for the students of the University of Forestry in direction “CNC MACHINES, TECHNOLOGIES AND TOOLS“
 
Key words: CNC machines, technologies, tools, education, CAD/CAM systems and modules

History
The Department of "Woodworking Machines" was found in 1953 and throughout the years has been named as follow: from 1953 to 1972 – “Machines and Tools”, from 1972 to 1994 – “Mechanization and Automation of Woodworking” (the curriculum included the discipline "Electronic Computing Equipment"). Due to the structural changes occurred in 1994 at the University of Forestry, two independent departments, namely: “Machine Science and Automation of Production” and "Electronic Computing Equipment" were separated sequentially and the old department was renamed to "Woodworking Machines".

The first head of the department:
• Assoc. Prof. Valko Gochev, PhD (1953 – 1966).

Consistently the heads of the department have been:
• Prof. Tacho Iliev, PhD (1966 – 1989);
• Prof. Georgi Filipov, DSc (1989 – 1990);
• Prof. Hristo Shehtov, DSc (1990 – 1993);
• Assoc. Prof. Petar Savov, PhD (1993 – 1999);
• Assoc. Prof. Stefan Velkov, PhD (1999 – 2002);
• Prof. Bozhidar Dinkov, PhD, (2002 – 2007);
• Assoc. Prof. Zhivko Gochev, PhD (2007 – 2016);
• Assoc. Prof. Vasil Vlasev (2016-2020);
• Assoc. Prof. Pavlin Vitchev (2021 – Present).

SUMMARY
 
The proposed project was developed in the following directions: comparatively experimental investigations on working capacity of wide band saw blades with setting, swaging and satellite – tipped teeth by sawing of pine and poplar logs.
The research works were carried out in the production conditions of the firms “Fagus Ltd. – Pernik, GP “Chakarov&Davidkov” – Boboshevo and Yundola Training Centre belong to University of Forestry.
They give answer to the questions what teeth do we use in the band saw blades: spring setting, swage setting, stellite tipping teeth when sawing of poplar and white pine wood and what are their advantages and defects as well. The quantitative and qualitative аnalyzes according to cutting processes and   wear-resistance of teeth were made.
The results were processed in the laboratory “Cutting of wood and woodworking tools” of the University of Forestry – Sofia. They will be exploited as in the practice, so in the instructional process as well.
The technology modes and the directions on the efficient use will be developed based on the investigations of the wide band saw blades with spring setting, swage setting or stellite tipping, according to the concrete production conditions.
The received solutions can be used in the workshop for processing round wood of Yundola Training Centre as interested from everybody as well companies from the practice. Moreover the samples of different band saw blades wee made as well photo materials showed separate technological stages of the teeth preparation. These materials will be used for the student needs out of the Speciality “Woodworking and furniture production” in the University of Forestry.
Key words: band saw blade, spring setting, swage setting, stellite tipping teeth, efficiency
