摘要： A numerical controller controls a three-axis machine tool that machines a workpiece, mounted on a table, with at least three linear axes. The numerical controller includes a workpiece mounting error compensation unit that compensates a mounting error caused when the workpiece is mounted. The workpiece mounting error compensation unit performs an error compensation with respect to an instructed linear-axis position with amounting error which is set beforehand, in order to keep a position with respect to the workpiece at a tool center point position, based on the instructed linear-axis position of the three linear axes to obtain a compensated linear-axis position. The three linear axes are driven based on the obtained compensated linear-axis position.

摘要： A numerical controller for controlling a multi-axis machine calculates an axis-dependent translation error amount and an axis-dependent rotation error amount based on a command axis position. Translation and rotation compensation amounts are calculated based on the axis dependent translation and rotation error amounts, respectively. The translation and rotation compensation amounts are added to command linear and rotary axis positions, respectively. Three linear axes and three rotary axes are driven to the added positions, individually. Thus, there is provided a numerical controller that enables even machining with a side face of a tool or boring to be in commanded tool position and posture (orientation) in the multi-axis machine.

摘要： A numerical controller for controlling a multi-axis machine tool having three linear axes and three rotating axes obtains an interpolated tool direction vector by interpolating a tool direction command and computes multiple solutions for three rotating axes from the vector. The three rotating axis positions are computed by synthesizing these multiple solutions. The three linear axis positions on a machine coordinate system are computed by adding to the interpolated tool center point position the product of the interpolated tool direction vector, or a verified tool direction vector based on the three rotating axis positions determined by the rotating axis position computing means, and a tool length compensation amount. The three rotating axes are moved to the positions computed above and the three linear axes are moved to the positions computed above.

摘要： A five-axis machining tool that machines a workpiece mounted on a table using three linear axes and two rotary axes is controlled by a numerical controller. The numerical controller calculates a translational compensation amount and a rotational compensation amount by obtaining axis-dependent translational compensation amounts and axis-dependent rotational compensation amounts on the basis of commanded axis positions. Then, the numerical controller moves the three linear axes and the two rotary axes of the five-axis machining tool to positions obtained by adding the translational compensation amount and the rotational compensation amount thus calculated to a command linear axis position and a command rotary axis position, respectively.
