| In order to increase the fused deposition modeling accuracy of parts and improve the machining quality of parts. A precision control method of fused deposition modeling based on Numerical Control (NC) machining is proposed. According to the part drawings, the automatic preparation of machining code is realized with the help of computer. Through the self-learning of fused deposition modeling precision, the fine-tuning value of fused deposition modeling is accurately generated, and then the precision control of fused deposition modeling is realized. The design control method has a lower control skewness coefficient than the control group in the same test time. It is proved that the design control method can ensure the precision of fused deposition modeling. |
