The tensions in the circular saw blade affecting the wood sawing quality, 1 The analysis of the factors affecting the wood sawing quality

Research subject and fields:

Unlike many other, wood engineering did not develop intensely until the end of the Second World War, when it was accompanied by the research of wood processing. Many requirements were fulfilled in terms of aesthetics, sociology, production, ergonomics. ecology, economics, technic, technology, and others. In order to improve these requirements, or at least maintain them, wood started to be researched together with the methods and results of its processing - from all the mentioned aspects. Since the particular factors influencing the production process are so numerous, it would be an intricate job to monitor them all in a single limited research in order to establish their interactions. Accordingly, the research of the best quality of wood processing machines involves the observation of the most effective factors, others, less powerful, being either omitted, or observed as a group. The improvement of wood processing is also based on the  adequate application of the research results, engineering/technical calculations, testing, and application of all these achievements to real issues. Due to the simple transfer of force and movement, from the drive motor to the cutting blade, the circular saw is the most frequently used sawing machine. Besides the stability of the blade during the process of particle separation, there are also the difficulues with the acceleration of the cutting speed, sliding speed and the blade diameter when its thickness is reduced. The   overall impact of these cutting obstacles may result in higher roughness of the cant surface, wider kerf, increased use of energy, etc. Bearing all this in mind, i have analysed the impact of design, energy and information upon the sawinng quality. This paper presents the evaluation of the processing regime as related to the sawing quality; it analyzes the effect ofthe circular saw blade, the blade wear, material, all in terms of the quality of cutting the cant surfaces. The analysis also encompasses the tensions caused by the centrifugal force, the impacts of temperature changes and saw blade strain. All radial and circular tensions caused by the centrifugal force are positive.
