The dataset and scripts produce an estimate for the effective area and distortion coefficient of the piston-cylinder assembly PCA2062 based on the 2020 dimensional characterization.The dimensional measurements of straightness, roundness, and two-point diameter for the piston and cylinder are in the text files:  \"straightnessPis.txt\", \"straightnessCyl.txt\", \"roundnessPis.txt\", \"roundnessCyl.txt\", \"radiusPis.txt\", \"radiusCyl.txt\"The main conversion script is:  \"CalcAeff2062.py\"This calls two other scripts to find the generatrixes of the piston and cylinder:  \"findGcyl2062.py\" and \"findGpis2062.py\"The conversion also relies on finite-element calculation.  These scripts are in the directory /fea.  All scripts and data from the /fea directory are controlled by the main conversion script CalcAeff2062.py.  To run the finite-element software will require a software license.", "distribution": [{"downloadURL": "https://data.nist.gov/od/ds/mds2-2698/2062.zip", "mediaType": "application/x-zip-compressed", "title": "Data 2062"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2698/2065.zip", "mediaType": "application/x-zip-compressed", "title": "Data 2065"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2698/2066.zip", "mediaType": "application/x-zip-compressed", "title": "Data 2066"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2698/README.txt", "mediaType": "text/plain", "title": "README"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2698/licensing.txt", "mediaType": "text/plain", "title": "Licensing"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-2698/pca206x-summary.pdf", "mediaType": "application/pdf", "title": "Pca 206x summary"}], "identifier": "ark:/88434/mds2-2698", "keyword": ["diameter", "effective area", "generatrix", "piston gage"], "landingPage": "https://data.nist.gov/od/id/mds2-2698", "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2022-07-06 00:00:00", "programCode": ["006:045"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "replaces": "ark:/88434/mds2-2698", "theme": ["Metrology:Dimensional metrology"], "title": "Conversion of a piston-cylinder dimensional dataset to the effective area of a mechanical pressure generator"}
