一种增材与减材复合制造机研究

Research on a composite machine for increasing material and reducing material

为了综合增材制造与减材加工的优点,研制了一台熔融增材制造与铣削减材复合加工机,采用龙门结构,总体尺寸为700 mm×640 mm×780 mm。该机床有3个直线轴和一个回转轴,控制系统采用MACH3控制系统。机床结构采用有限元软件Abaqus进行了优化和分析,并制造了样机。针对PEEK材料脊柱融合器,在该样机上进行了增材与减材制造,验证了所研发机床的性能以及该复合制造机床在医疗PEEK材料增减材制造的潜力。

In order to achieve both the processes advantages of fused deposition modeling （FDM） and mechanical cutting, a novel miniaturized machine tool with combined processing capabilities is designed and developed. The miniaturized machine tool is designed using the gantry structure and its overall size is 700 mm × 640 mm × 780 mm. The machine tool has three linear axes and one rotary axis. The control system adopts the MACH3 system. The finite element software Abaqus is applied to analyze and optimize the designed structure. Furthermore, the model machine is manufactured. Aiming at the PEEK material spine fusion device, the material increase and material reduction manufacture experiment has been conducted on the model machine. It has successfully verified the performance and the potential capacity of the material increase and material reduction manufacture for medical PEEK material of the developed compound manufacture machine tool.
