The near net shape extrusion-forging and the impact of tooth filling computationally simulated and experimentally corroborated. The study plans to search for the finishing forging process's essential station and recognize the unique gear teeth forming in the closed die near net shape extrusion-forging connected with a multicore cable cutter. Due to make sure to realize the Preform types of gear teeth forming, The evaluation index of the height filling ratio (HFR) and the width filling ratio (WFR) methods are offered and simulated with a singular target on process parameters at the gear teeth making. All the objects are regularly investigated and precisely contrasted to experimental examination. The simulations' conclusions have explained the microscopic events after the experimental research. Via matching with experimental measurements, the accuracy of the numerical models has been confirmed. The offered modified geometries (Preform B and C) from the forming process have been eventually offered to achieve a resembling forming condition while lessening making charges.. The mean deviation of HFR was measured as 0.987% and 0.985% for Preform B and C, respectively. Moreover, the mean deviation of WFR was calculated as -0.693% and − 0.74% for Preform B and C, separately.

In this study, a forming process during producing medical surgery curve cutter stapler would be tentatively as well as numerically investigated and validated by the simulations. The reasons for the investigation are to find the critical technology of the forming process and to understand this medical tool head forming within the forming process associated with medical surgery curve cutter stapler and improve the traditionally forming process. Moreover, to understand the medical tool head forming, the novel forging process, and the parting line approach are offered and simulated by the FE software QForm, the method data on the medical tool head forging are investigated and compared with the experimental analysis. According to the outcomes of the simulations, the distributions of the forming process, some parameters have been gotten to explain and improve these microscopic phenomena. The precision of the numerical patterns has been confirmed by comparing them with the test dimensions. The offered revised model from the forming preform has been submitted to achieve an alike forging condition when reducing manufacturing cost After the improved method, measure the shrinkage width of the workpiece. Compared with the product of the traditional process, the widest area is 6.37mm shrink to 6.29mm. The shrinkage is about 1%. Compared with the previous result is 5%, the improvement plan has been optimized the outcomes very much.
