Abstract
Official abstract text for this publication.
A machine tool includes: a column movably supported on a bed; a saddle movably supported on the column; a ram movably supported on the saddle; moving means for moving the column, the saddle, and the ram respectively along movement axes; a table where a workpiece is placed; table-tilt detecting means for detecting atilt of the table; and controlling means for controlling the moving means based on a detection result from the table-tilt detecting means.
First claim
Opening claim text (preview).
1 . A machine tool comprising: a column movably supported on a bed; a saddle movably supported on the column; a ram movably supported on the saddle; moving means for moving the column, the saddle, and the ram respectively along movement axes; a table where a workpiece is placed; table-tilt detecting means for detecting a tilt of the table; and controlling means for controlling the moving means based on a detection result from the table-tilt detecting means. 2 . The machine tool according to claim 1 , further comprising: a main spindle supported on the ram; and a tool attachably and detachably mounted on the main spindle, wherein the controlling means performs a control such that the moving means moves at least one of the column, the saddle, and the ram to correct a mismatch in relative position of the tool and the workpiece. 3 . The machine tool according to claim 1 , wherein the table-tilt detecting means comprises height detecting means for detecting heights of a plurality of measurement points on the table to thereby obtain a tilt level of the table from a difference between the heights of the plurality of measurement points detected by the height detecting means. 4 . The machine tool according to claim 3 , wherein the height detecting means is a plurality of distance sensors provided at positions below the table, and the measurement points are located on a lower surface of the table. 5 . The machine tool according to claim 1 , further comprising column-tilt detecting means for detecting a tilt of the column, wherein the controlling means controls the moving means based on detection results from the table-tilt detecting means and the column-tilt detecting means.
