| 20080288103 | Numerical control method for five-axis processing machine - If the angle α formed between the interpolated cutting surface perpendicular direction vector (It, Jt, Kt) and the interpolated tool direction vector (Ttx, Tty, Ttz) becomes smaller, movement of a tool becomes unstable. In this case, the tool diameter compensation vector (TCx, TCy, TCz) is set to the tool diameter compensation vector calculated in the immediately previous interpolation cycle, thereby preventing unstable movement. Further, in case of a block instruction where a distance between positions in cutting point instructions is large whereas distance of movement of linear axis control point is small, an excessive cutting may occur. To deal with this problem, movement of linear axis control point in a current block is stopped or converted into linear movement so as to prevent a loop-shaped movement of the linear axis control point. | 11-20-2008 |

| 20120191238 | CONTROL DEVICE AND CONTROL METHOD OF FIVE-AXIS CONTROL MACHINE TOOL, PROGRAM, AND MOLD - A five-axis control machine tool stores rotation-axis data indicating the inclination or runouts of each of a rotation axis A of a tilting table and a rotation axis C of a rotating table in association with rotation angles determined based on NC data, and calculates a correction rotation angle of each of the rotation angles A and C to correct the erroneous attitude of a tool. Five-axis control is performed based on the NC data by rotating the tilting table and the rotating table about the rotation axes A and C at the correction rotation angles, so that a workpiece is machined while eliminating the erroneous attitude of the tool. | 07-26-2012 |
| 20120221141 | NUMERICAL CONTROLLER HAVING SPEED CONTROL FUNCTION FOR MULTI-AXIS MACHINING DEVICE - When a numerical controller executes a tool-center-point control in which a path of a tool center point with respect to a workpiece is instructed, and the workpiece is machined along the instructed path based on a speed instruction, the numerical controller sets the speed instruction so that the speed instruction is a synthesis speed with respect to a synthesis distance of a relative moving distance between the workpiece and a tool center point and a tool-direction changing distance due to a relative change in a tool direction with respect to the workpiece by a rotary axis. The numerical controller interpolates a position of a linear axis and a position of a rotary axis by the tool-center-point control according to the synthesis speed and drives the linear axis and the rotary axis to the position of the linear axis and the position of the rotary axis created by the interpolation. | 08-30-2012 |
