Design and Testing Of the Precise Cutting Test Bed for Micron Paring Machining

摘要

The test bed for micron paring machining is a kind of Computer numerical control (CNC) carpentry test beds. Movement of machine is controlled automatically according to processing instructions, machining of different raw materials can be realized by simply changing the processing instruction program. The test bed's precision and its persistence are mainly guaranteed by the lathe bed, and have an air clamping device and its feeding mechanism includes a stepper motor for CNC feeding. At the end of the thesis, the conclusion of experiment presents widths of micron parings machined by cutting lengthways along the grain fall between 50～150 μm. With further analysis, around 72% of the parings are 60～100 μm thick, around 75% are 5～8 mm wide, around 78% are 65～75 mm long. The results show micron parings machined by the specialised test bed meet the design requirements for micron parings.
