碩士 === 國立勤益科技大學 === 機械工程系 === 106 === This thesis mainly is a design to apply machine tool of process for composite materials, this model is a gantry type light 5-axis structure. Work area takes a double table, and accompany with by auto exchange from the programmable control, accomplish quick exchange the workpiece, it can also enhance utilization. In addition, spindle system takes a 2-axis head, accompany with by multi-angle process applications. The forming of composite materials parts is according to require model, Most of thin parts and the surface. The study problems of clamping parts, drilling and milling for the composite materials parts. Common problems include the deformation of parts by clamping, caused burr by drilling, milling is difficult to cut fibers then caused fiber break or delamination and raise a dust. Through this thesis is a design of the process machine tool for composite materials to solve the problems in the milling. The design of the machine tool structure use the steel welding accomplish lightweight, different from casting of metal machine tool, and accompany reduce weight by 45%. The drivetrain system is driven by gear and rack, it replace ballscrew drive, and accompany high feed speed of 40m/min, cutting feed speed of 20m/min. The spindle speed takes a 24000rpm make easy cut the fiber and reduce burr, and accompany enhance quality of parts processing. With the design concept bases on the study, the performance of the machine tool improves significantly. Last but not least, the machine tool satisfies the requirements of CFRP machining in the industry and successfully raises the interests of the buyers in the well design machine tool.
