Abstract

One end of the telescopic bar (3) is mounted on the spindle (2) of the NC machine tool and the other end on the machine table (15). The machine tool is numerically controlled so that one end of the bar takes a circular nterpolation motion relative to the centre of the rotary joint of the other end in any of the working planes of the machine. The telescopic movement at each rotational angle is memorised and recorded to evaluate and analyse motion errors of the tool. Origins of errors are defined referring the test results to prepared trace patterns of typical origins. The obtained data are processed chiefly by a microcomputer which is accompanied by a CRT display, a floppy disc memory, a keyboard and an XY plotter.
