The objective of this research is to understand the sources of contamination of mechanical components by manufacturing byproducts. This understanding will be used to establish methodologies for cleaning-conscious design feedback to product developers, improved process planning for manufacturing, and optimization of mechanical cleaning technologies. Reducing and preventing solid particle contamination (such as detached burrs and chips from machining and sand from casting) on the surfaces of mechanical components and improving the effectiveness of cleaning will be addressed throughout the product development chain, from the early stages of product design and prototyping to finishing processes and quality assurance in manufacturing. Specifically, this research will: i. develop metrics and measurement methodologies for cleanliness and cleanability, ii. improve our theoretical understanding of geometric aspects of cleaning, validated by experimental data, iii. propose new methods for modeling and solving constrained accessibility problems, iv. develop efficient algorithms and data structures to support automated process planning for cleaning and assessing ease of cleanability (Design for Cleanability (DFC) software for designers allowing informed decisions trading off cleanability against functionality), and, v. study the trade-offs between cleanability and functionality from a component design standpoint.If successful, this research will result in a methodology for addressing contamination related part design, processing and cleaning issue. The benefits will include a significant improvement in product quality, reduction in the cost of warranty claims due to residual contaminants and a substantial reduction in the consumption of cleaning related energy and consumables. Student participation at Berkeley will result in an excellent training experience and preparation for industry careers or additional study.

本研究的目的是了解制造副产品对机械部件的污染来源。这种理解将被用来建立清洁意识的设计反馈给产品开发人员，改进制造工艺规划，优化机械清洁技术的方法。 减少和防止机械部件表面的固体颗粒污染（如机加工产生的脱落碎屑和碎屑以及铸造产生的砂）以及提高清洁效率将贯穿整个产品开发链，从产品设计和原型制作的早期阶段到制造过程中的精加工过程和质量保证。具体而言，本研究将：i。制定清洁度和可清洁性的指标和测量方法，ii.改进我们对清洗的几何方面的理论理解，通过实验数据验证，iii.提出新的建模方法和解决约束可达性问题，iv.开发有效的算法和数据结构，以支持自动化的工艺规划，用于清洁和评估易清洁性（可清洁性设计（DFC）软件，供设计人员在可清洁性和功能性之间进行权衡时做出明智的决定），以及，v.从组件设计的角度研究可清洁性和功能性之间的权衡。如果成功，这项研究将导致一种方法，解决污染相关的部分设计，加工和清洁问题。其好处将包括显著提高产品质量，降低因残留污染物而导致的保修索赔成本，以及大幅减少清洁相关能源和耗材的消耗。在伯克利的学生参与将导致一个优秀的培训经验和行业职业生涯或额外的学习准备。
