  • Method for scraping off excessive portion of workpiece
    Patent number: 5331770
    Abstract: In a method for scraping off automatically an excessive portion of a workpiece by a cutting tool, a surface shape of the excessive portion of the workpiece is measured, a cross-sectional area variation of the excessive portion along a feed course in which the cutting tool will proceed during a cutting operation thereof is calculated from the measured surface shape of the excessive portion, and the excessive portion is scraped off in the feed course with a feed speed of the cutting tool which is changed in accordance with the calculated cross-sectional area variation of the excessive portion along the feed course, so that the larger the calculated cross-sectional area of the excessive portion is, the smaller the feed speed of the cutting tool is, and the smaller the calculated cross-sectional area of the excessive portion is, the larger the feed speed of the cutting tool is.
