Work installation feature or the measurement jig, and measuring method of the rotary table which is used for the measurement of the processed datum point on the revolving shaft which inclines

摘要

P To provide a rotary table or a measuring tool capable of measuring three-dimensional positions of a working reference point of a rotation axis in an inclined state in a machine tool for working in which the rotation axis is fixed in an inclined state by an arbitrary angle larger than 0 degree and smaller than 90 degrees during the working and a measurement method. PSOLUTION: A first measuring tool 1 fixes an attachment surface 1f to a workpiece attachment surface of a workpiece fixing bracket 26. A conic surface 1c of the first measuring tool 1 has its generating line horizontal when attached to the inclined rotation axis and wall surfaces 1b and 1d vertical to the conic surface 1c are formed to be parallel in a vertical direction. A symbol 1g shows the working reference point. In addition and a symbol 1h shows a groove center line of a groove 1a. A symbol 1i shows a distance between the wall surface 1b and the wall surface 1d, a symbol 1j shows a distance between the working reference point 1g and the conic surface 1c and a symbol 1k shows a distance between the reference point 1g and the groove center of the groove 1a.
