QC小组活动的发展和深化过程,实质上是PDCA循环不断运转和提高的过程,这样的运转和提高不能单靠奖金来达到,而要运用综合措施才能凑效。现提出以下意见,供研究与探讨。亚加强领导开展QC小组活动是推进全面质量管理,增强职工质量意识的重要途径,是实现加强企业科学管理和民主管理的好形式。当职工通过队小组活动在提高效益、降低消耗和增强产品的竞争能力中取得成绩时,内心会感到无限的自豪和喜悦,从而会激发出更大的干劲。队小组活动开展得越深入,职工的主人翁态度越强,对企业的"双文明"建设会带来重要的作用。所以,企业领导… 相似文献

企业长期的实践证明,产品要进入市场,被用户所接受,标准化工作必须先行,特别是加入WTO后,随着汽车产品进入国际市场,无论是在国内,还是国外,市场竞争越演越烈。无数商机充满着“机遇”,但面对国内外市场、面对同行业新老对手的竞争和挑战,企业的标准化特别是产品的标准化更应适合于市场。所以说,企业标准化是企业自身发展的需要。 相似文献

A honeycomb structure is widely used in sandwich structure components in aeronautics and astronautics; however, machining is required to reveal some of its features. In honeycomb structures, deficiencies, such as burrs, edge subsiding, and cracking, can easily appear, owing to poor specific sti ness in the radial direction. Some e ective fixation methods based on a filling principle have been applied by researchers, including approaches based on wax, polyethylene glycol, iron powder, and(especially) ice. However, few studies have addressed the optimization of the cutting parameters. This study focused on optimizing the cutting parameters to obtain a better surface roughness(calculated as a roughness average or Ra) and surface morphology in the machining of an aluminum alloy honeycomb by an ice fixation method. A Taguchi method and an analysis of variance were used to analyze the e ects and contributions of spindle speed, cutting depth, and feed rate. The optimal cutting parameters were determined using the signal-to-noise ratio combined with the surface morphology. An F-value and P-value were calculated for the value of the Ra, according to a "smaller is better" model. Additionally, the optimum cutting parameters for machining the aluminum honeycomb by ice fixation were found at different levels. The results of this study showed that the optimal parameters were a feed rate of 50 mm/min, cutting depth of 1.2 mm, and spindle speed of 4000 r/min. Feed rate was the most significant factor for minimizing Ra and improving the surface morphology, followed by spindle speed. The cutting depth had little e ect on Ra and surface morphology. After optimization, the value of Ra could reach 0.218 μm, and no surface morphology deterioration was observed in the verified experiment. Thus, this research proposes optimal parameters based on ice fixation for improving the surface quality. 相似文献

AFM-based wear process actually is single abrasive abrasion process. It is widely employed in the surface micro/nano machining
for fabrication of structures at the nanometer scale exhibiting high removing ability of nanometer scale materials. In this
study, application of AFM-based single abrasive abrasion process in the local surface quality (surface roughness) improvement
was studied. Merged holes were fabricated using an AFM diamond tip with different wear parameters on the surface of germanium
(Ge) machined by conventional ultra-precision diamond turning. Results showed that cracks left by diamond turning can be removed
and the local surface quality can be improved. Also effects of the wear parameters on the surface roughness were investigated.
The optimized parameters of the abrasion process for improving the surface quality were provided. It is verified that AFM-based
single abrasive abrasion process is a novel approach to modify or repair local surface on the surface of parts manufactured
by other methods. 相似文献

基于作业质量成本的质量改进决策模型研究 总被引:5,自引:1,他引:5
根据质量改进的经济特性,提出了应用质量成本可以为质量改进决策提供有效依据的观点,论证了传统的质量成本分析具有狭隘且针对性不强的缺点。基于过程的思想,综合考察产品的实现过程,提出了“基于作业的质量活动链”的概念,并在此基础上建立了作业质量成本管理体系。论述了各项活动发生的质量成本是相互影响的,要从全局的角度系统地对质量成本进行分析。研究了一种基于作业质量成本的,主要由质量成本数据库、质量改进决策支持系统、预测系统组成的质量改进决策模型,为基于作业质量成本分析的质量目标优化、质量改进方案设计提供了方法。 相似文献
