POSITON ERROR CORRECTION DEVICE OF CLOUM IN SUPER-SIZE MACHINE TOOL AND METHOD THEROF

摘要

It is an object of the invention to detect the thermal stress for arranging generation caused by the margin of error of position, according to the frictional heat generated by temperature, when processing works in lock formula machining center and ambient enviroment. If location error amount is more than tolerable limit, the column of location error amount detection are corrected a column position correction unit, to reduce the column of location error correction time and cost. The workpiece of processing accuracy can be improved in a kind of location error means for correcting of machine pillar and its bearing calibration. ;The 2015 of copyright KIPO submissions
