摘要： A numerical control device includes a retraction-direction decision unit that decides a retracting direction of the tool when determining that the tool deviates from the movable range, and a tool-locus correction unit that corrects a locus of the tool based on this retracting direction so that a distance between the tool and a rotation center of a table while retracting is equal to or larger than a distance between the tool and the rotation center of the table at a time of either the start of rotation of the table or the end of the rotation of the table. According to the present invention, it is possible to avoid a stroke-over while avoiding interference between the tool and a workpiece when a table rotation command that possibly causes a stroke-over on the linear axis is issued while executing a control on a coordinate system other than a machine coordinate system.

摘要： A CPU 41 reads a next block (S1), and then determines whether the read block is a TCP (tool center point) control finish command “G49” or not (S2). If it is determined to be the TCP control finish command “G49”, the TCP control is finished. If it is determined not to be the TCP control finish command “G49”, whether the read block is a coordinate-system transformation command “P1” or not is determined (S3). Next, if it is determined not to be the coordinate-system transformation command “P1”, the TCP control is performed, without transforming the coordinate system, in accordance with a command of the block (S11). Next, the process returns to S1, and then the process after S1 is executed. If it is determined to be the coordinate-system transformation command “P1”, a start point (xs, ys, zs, bs, cs) and an end point (xe, ye, ze, be, ce) in a non-machine coordinate system, of the block are transformed into a start point (Xs, Ys, Zs, Bs, Cs) and an end point (Xe, Ye, Ze, Be, Ce) in a machine coordinate system, respectively (S4).
