PARALLEL-TYPE MACHINING TOOL FOR MACHINING COMPOSITE SHAPES, EXECUTING CORRECTION OF THE MACHINING CENTER, AND DEVELOPING A PC-BASED CAD/CAM(COMPUTER AIDED DESIGN/COMPUTER AIDED MANUFACTURING) SYSTEM FOR DESIGNING AND MACHINING FREE SHAPES

摘要

Purpose: a parallel type machining tool is used to process combined type and is arranged to carry out correction work by freely adjusting the height for the plane that one limits and examining the observability of a constrained motion by one or three digital indicators and an attachment surface and one optimal correction shape of search, if having to decompose by using QR- keeps independently reaching for a line vector maximum. Construction: in a parallel-type machining tool is examined for processing combined type, observability according to constrained motion, and an optimal correction shape is found. One observable becomes top and is estimated, and coordinate system is studied. Restrict the plane that the plane of movement is limited using one or three digital indicators and one. Optimal correction shape, which decomposes an observation matrix by QR-, maximizes the independent of a line vector. The quantity that observable becomes top is provided with the grade from observation matrix. According to a bound variable, a value, for indicating the independence of line vector, being defined and minimizing inspection observability.
