Machining processes in furniture industry
Černý, Marek ; Kalivoda, Milan (referee) ; Chladil, Josef (advisor)
This master thesis deals with machining processes in the furniture industry. Various group of materials, which are used in furniture industry are described there. Then there are described assembly and machining processes, such as manual and machine. In practical part, the production process for the selected sample product was proposed. The production was performed in a specific company, which has suitable machinery and tools. Sample product was made from double-sided laminated medium density fibreboard, which belongs to the group of wood-based materials. As a part of the debugging produciton process, the dependence tool life at cutting speed was experimentaly found. The experiment was performed on CNC milling machine with cutting speeds in the range 453 to 905 m.min-1, width draft of cutting edge 9,5 mm and feed per tooth 0,05 mm. Analog passametr Somet with an accuracy 0,001 mm was used to measure tool wear. The measured data were recorded and evaluated in program Excel. The resulting dependency tool life at cutting speed can be used in other machining operations. After performing the experiment, each parts of the product were produced and mountig was performed. The conclusion of the thesis contains an evaluation of the proposed production process.
