Oil particles generated from metalworking fluids(MWFs) in machining process can lead serious health problem to operator. Local exhaust hood is an effective engineering method capture oil and other contamination which wildly used manufacture workshop. In this paper, efficiency with various height, air volume particle size was gotten by Computational Fluid Dynamic(CFD) technology. Though further ...

Occupational exposure to aerosolized particles of oil-basedmetalworking fluid was recently linked to deaths from ischemic heart disease. The current recommended exposure limits might be insufficient. Studying cardiovascular mortality is challenging because symptoms can induce sicker workers to reduce their exposure, causing healthyworker survivor bias. G-estimation of accelerated failure time m...

Due to its desirable mechanical properties, compacted graphite iron (CGI) has been used replace conventional gray cast (CI) in various applications, such as automotive engine blocks and cylinder heads. However, the poor machinability of CGI can lead excessive tool wear consequently high manufacturing costs. Various strategies have developed improve CGI, including optimizing machining parameters...

Lightweight materials like Carbon Fiber Reinforced Polymers (CFRPs) present certain challenges, mainly regarding the resultant surface integrity of holes. Different techniques such as optimized tool geometries, machining and cooling/lubricating have been tested for improving on CFRPs. Unfortunately using coolants presents challenges when CFRPs, moisture absorption can degrade mechanical propert...

Occupations with mineral oil exposure have been associated with bladder cancer in population-based case-control studies. The authors report results from the first cohort study to examine bladder cancer incidence in relation to quantitative exposures to metalworking fluids (MWFs), based on 21,999 male Michigan automotive workers, followed from 1985 through 2004. Cox regression was used to estima...
