使用阿博格自由成型工艺免工具生产金属部件的工艺模型

基本信息

项目摘要

The Project Process model for the tool-free production of metallic components with the Arburg Freeforming Process will expand the conventional tool based Metal Injection Molding (MiM) process, through the use of a metal Feedstock along with the Arburg Freeforming Process, to a flexible MIM Process. This presents a new, flexible approach for the generative production of metallic components. Due to high similarities to the conventional injection molding process it has a high capability in terms of component quality (shape-persistence and mechanical properties). Additionally it has high economic potential due to the absence of shaping molds. On the basis of the novelty of the Arburg Freefoming Process, the process has yet to be examined and there are no recommendations as to a process design or model. In order to harness the available potential, the influences and interactions of materials, process and nozzle geometry parameters have to be statistically evaluated through a design of experiments (DoE). The approach target is to evaluate the flexible MIM process for the production of metallic components from the material 17-4PH, which is regarded as representative due to its widespread use in industry. By means of this experimentation a process model should be developed. Alongside will be evaluated two sequential series of experiments each with different sample geometries. In the first series of experiments the influence and interaction of materials, process and nozzle geometry parameters on the outcomes of dimensional stability (dimensional stability, flatness, roughness) and mechanical properties (tensile strength, hardness, density) will be determined based on tensile specimens and cubes. These geometries have simple geometry specifications (no complex transitions) and therefore allow the detection of mechanical characteristics (e.g. tensile strength, density) for creating a basic process model. In the second test based on a complex geometry, a gear which has complex geometry specifications (tooth flank curves), the existing process model will be validated (investigation of previous variables) and enhanced (investigation of new variables: dimensional tooth flank curves). The choice of factor levels for the parameters to be varied will be derived from the results of the first test series. A result should not only include descriptive process model equations for the flexible MIM process but also recommendations for materials, process and nozzle geometry parameter choices for future applications and materials. The expected results will form the basis for process understanding and process optimization, which will ultimately be reflected in a high component quality.
使用Arburg自由成形工艺生产金属部件的项目过程模型将通过使用金属原料和Arburg自由成形工艺,将传统的基于工具的金属注射成型(MiM)工艺扩展为灵活的MiM工艺。这为金属部件的生成生产提供了一种新的、灵活的方法。由于与传统注射成型工艺高度相似,它在部件质量(形状持久性和机械性能)方面具有很高的能力。此外,由于没有成型模具,它具有很高的经济潜力。基于Arburg自由成形过程的新颖性,该过程尚未进行检查,并且没有关于过程设计或模型的建议。为了利用现有的潜力,材料、工艺和喷嘴几何参数的影响和相互作用必须通过实验设计(DoE)进行统计评估。该方法的目标是评估17-4PH材料生产金属部件的柔性MIM工艺,该工艺因其在工业中的广泛应用而被认为是具有代表性的。通过这种实验,应该建立一个过程模型。此外,还将评估两个连续的系列实验,每个实验都具有不同的样品几何形状。在第一个系列的实验中,材料、工艺和喷嘴几何参数对尺寸稳定性(尺寸稳定性、平整度、粗糙度)和力学性能(抗拉强度、硬度、密度)结果的影响和相互作用将基于拉伸试样和立方体来确定。这些几何形状具有简单的几何规格(没有复杂的过渡),因此可以检测机械特性(例如抗拉强度、密度),从而创建基本的工艺模型。在第二个基于复杂几何结构的测试中,一个具有复杂几何规格(齿面曲线)的齿轮,将验证现有的工艺模型(调查先前的变量)并增强(调查新的变量:尺寸齿面曲线)。要改变的参数的因子水平的选择将从第一个测试系列的结果中得出。结果不仅应包括柔性MIM工艺的描述性过程模型方程,还应包括未来应用和材料的材料,工艺和喷嘴几何参数选择的建议。预期的结果将形成过程理解和过程优化的基础,最终将反映在高组件质量中。
