Optimization of casting process involves the adjustment of parameters as well as the improvement of process schemes and measures. This paper proposes a new method based on the Theory of Inventive Problem Solving (TRIZ) for casting process optimization, and realizes the idea of applying TRIZ to optimize the casting process of a magnesium alloy intake manifold. By this method, the casting process is optimized so as to remove the shrinkage pores. The successful optimization of casting process demonstrates the feasibility of the proposed method. 相似文献

Induction-coupled plasma deposition (ICPD) is currently a laboratory process relying on operator expertise rather than automated control. Intelligent process control for the ICPD process, which consists of integration of processing knowledge, process models, process sensors and control technology, offers the opportunity to provide closed-loop control as well as intelligent supervisory control to accelerate process development and bring the ICPD process to full-scale production. Intelligent process control for ICPD offers benefits such as higher material quality, control of the matrix micro-structure, cost reduction, higher process yield, and shorter development and production cycle times. 相似文献

智能工艺设计是智能制造的技术关键和基础。为了提高工艺设计效率,提出一种基于参数化工艺模板的智能工艺设计方法。其基本思路是利用参数化方式将工艺模板中的可变信息通过参数来进行表示,并以参数表达式和融合规则的方式建立工艺信息、工艺参数和零件参数的参数化关系,从而基于参数的驱动实现工艺智能设计。重点阐述参数化工艺模板方法中工艺、参数以及规则的表示,并对基于参数化工艺模板的工艺推理流程进行详细讨论,最后以筒形件的旋压工艺设计为例进行了智能工艺设计的验证,说明该方法易实现、效率高。 相似文献

A variant from the laser-arc hybrid welding process family which combines a pulsed laser process (Nd:YAG) and a pulsed (micro)TIG welding process is described.For studying the present variant process’ characteristics experimental work was carried out using video data acquisition and thermal imaging. In this paper, the characteristics of the present hybrid welding process variant and the influence of TIG welding parameters onto the process stability and the welding process result are presented. The experimental work revealed that the transient hybrid coupling phenomena, which is specific to the present hybrid process variant, has an important influence onto the process stability and the processing result. At the same time a strong interaction between the controlled process parameters was observed and that rather small changes to the process parameters values have a strong effect onto the process stability. The recommended TIG frequency domain for using as well as the variant which provides the best option to attenuate the penetration variation, specific to pulsed laser welding, was determined. The TIG frequency values which seem to lead to a stable welding process are of the same order as the ones used for laser pulse repetition rates. The variant that leads to an attenuation of the penetration is pulsed TIG-laser (with TIG as the leading process). 相似文献

现有文献资料上对410不锈钢锻后退火的工艺提法不同,为了确定适合的退火工艺,根据现有文献资料,选取不同参数进行试验,通过对硬度和金相组织的对比,确定了780℃退火、保温2.0~3.0 h、出炉后自然空冷的不完全退火工艺,并严格执行410不锈钢锻造工艺,控制终锻温度在900℃以上。该工艺在生产中进行了实践,结果证明,退火工艺达到了保证180~220 HBW的硬度范围、提高切削性能的预期。此不完全退火工艺与完全退火工艺相比,锻件的硬度合格率、机械加工性能和生产效率都得以提高,产品最终力学性能也得到了相应的提高,从而说明了该退火工艺具有较强的实用性和良好的经济效益。 相似文献
