摘要:
A unit vector calculating unit of a laser machining device obtains a unit vector based on respective current rotational positions of an A-axis and a B-axis. A movement command calculating unit, a speed command calculating unit, or a torque command calculating unit generates a command signal for maintaining a gap amount at a constant value, based on the unit vector, and the gap amount between a machining nozzle and a workpiece. With a servo control unit, on the basis of the command signal, an X-axis motor, a Y-axis motor, and a Z-axis motor are controlled, whereby the machining nozzle is moved relatively in three-dimensional directions with respect to the workpiece.

A numerical controller obtains a necessary moving distance for the completion of movement in each interpolation period, based on a moving distance for each block and the input ratio of a distance by which movement is completed in each interpolation period to the moving distance for each block. If the obtained moving distance is shorter than the moving distance for each interpolation period based on an initially set feed speed, the feed speed is changed to a speed for moving the moving distance in each interpolation period.

摘要:
A controller performs gap control such that a Z-axis position of a tip of a cutting head of the machine is not below a preset lower limit position while keeping the distance between the tip of the cutting head and a workpiece constant. The numerical controller calculates a substantial lower limit position based on a detected state of the workpiece and the preset lower limit position. If the Z-axis position of the tip of the cutting head is below the calculated substantial lower limit position, it is compensated so as not to be below the substantial lower limit position.

摘要:
A numerical controller includes a neighboring point search function that moves a tool controlled by a moving axis and a rotation axis onto a machining path directed by a machining program within the range of a neighboring point distance from a current position of the tool. When searching the neighboring point, the numerical controller determines a neighboring point with consideration for both a tool center point position and a tool attitude. By employing this search method, even when a plurality of block start points are present in the neighboring point distance from the current tool position, a block start point of the block originally desired to be restarted can be determined as a neighboring point.
