Analysis of cutting process of thermally modified wood using circular saws
Kasal, Tomáš ; Sarvašová Kvietková, Monika (advisor) ; Kubš, Jiří (referee)
The aim of the thesis Analysis of cutting process of thermally modified wood using circular saws is to present a comprehensive summary of available findings and knowledges about this particular process. The first part of the study deals with the circular saws, its history, division and particularly characteristics of the blade, as well as its geometry, possible materials for its production and maintenance. In the second part is described the process of cutting itself, namely the features which accompany the process, also the kinematics of circular saws, cutting resistance and cutting force. The third part deals with thermally modified wood, its principles, the production processes, features and machining of thermo wood using circular saws.
Conveyor with clamping and measuring
Polák, Aleš ; Koutecký, Tomáš (referee) ; Dvořáček, Jiří (advisor)
The first profile of the thesis describes current methods of segmenting and measuring of aluminium profile and analysis of a specific roller conveyor with a measuring device for feeding aluminium profile to a high-speed circular saw. The second section is focused on designing a new conveyor with clamps for feeding aluminium profile and designing measuring equipment based on the analysis in the first part.
Kvalita řezné spáry při podélném rozmítání dřeva speciálními pilovými kotouči
Kryl, Jan
The thesis is focused on qualities problems of the cutting kerf rip saw-blade at along grain cutting native wood. The effect of vibrations of circular saw-blades and feed rate of shift of workpiece on the quality of the kerf has being investigated. The basic parameters of evaluation of the surface were mentioned in theoretical part of this thesis. Also, the methods of assessing the quality of the surface of scattered timber are analyzed inside this thesis. There is also described suitability of different measurement methods, which have been used, due to the nature of solid wood. Finally, constructional modifications of scattering discs are characterized here. At practical part of this thesis is compared the quality of surface of wood scattered with using of saw-blades from company of PILANA. Discs with standard profile of tooth and special toothing of shaped keg were used.
Energetické parametry obrábění kompresně plastifikovaného a chemicky modifikovaného buku
Růžička, Dominik
This thesis is concerned with machinability and energy variables of compression- plasticized beech Bendywood?, chemically modified beech Belmadur? and chemically plasticized and compressed beech Lignamon? when cutting the saw and cut to define the appropriate model and its parameters. Calculated values of cutting resistance are compared with the values of natural beech and beech modified experimentally determined on a test rig to simulate cutting circular saw.
