LASER MEASURING SYSTEM AND METHOD FOR TURNING MACHINE

摘要

LASER MEASURING SYSTEM AND METHOD FOR TURNING MACHINE A laser measuring system is associated with a two axis turning machine (10),having a tool turret (12), to permit the dimensions of a machined part to be ascertained without removal of the part or workpiece from the chuck (18) of the machine. A gage head (36), which includes a retroflector (40), is mounted upon the turret which is indexible to a measuring station in which part measurements may be taken. The turret is mounted upon an X-axis slide (32) movable perpendicular to the chuck axis which, in turn, is mounted upon a Z-axis slide (26) movable parallel to the chuck axis. An interferometer (48) is fixedly attached to the Zaxis slide so as to be in alignment with the retroflector when the retroflector is in the measuring station. A Laser beam source (52) and a beam receiver (54) are mounted on or adjacent the machine such that they are in proper alignment with the interferometer. A collar (20) on the chuck furnishes a reference surface which functions as a fixed gage calibration point.
